Aims. The aim of this meta-analysis was to assess the prognosis after early functional rehabilitation or traditional immobilization in patients who underwent operative or nonoperative treatment for rupture of the Achilles tendon. Methods. PubMed, Embase, Web of Science, and Cochrane Library were searched for randomized controlled trials (RCTs) from their inception to 3 June 2020, using keywords related to rupture of the Achilles tendon and rehabilitation. Data extraction was undertaken by independent reviewers and subgroup analyses were performed based on the form of treatment. Risk ratios (RRs) and weighted mean differences (WMDs) (with 95% confidence intervals (CIs)) were used as summary association measures. Results. We included 19 trials with a total of 1,758 patients. There was no difference between the re-rupture rate (RR 0.84 (95% CI 0.56 to 1.28); p = 0.423), time to return to work (WMD -1.29 (95% CI -2.63 to 0.05); p = 0.060), and sporting activity (WMD -1.50 (95% CI -4.36 to 1.37); p = 0.306) between the early functional rehabilitation and the traditional immobilization treatment strategies. Early rehabilitation up to 12 weeks yielded significantly better Achilles tendon Total Rupture Scores ((ATRS) WMD 5.11 (95% CI 2.10 to 8.12); p < 0.001). Patients who underwent functional rehabilitation had significantly lower limb symmetry index of heel-rise work ((HRW) WMD -4.19 (95% CI -8.20 to 0.17); p = 0.041) at one year. Conclusion. Early functional rehabilitation is safe and provides better early function and the same functional outcome in the longer term. Cite this article: Bone Joint J 2021;103-B(6):1021–1030

We reviewed the records of 107 consecutive patients who had undergone surgery for disruption of the knee extensor mechanism to test whether an association existed between rupture of the quadriceps tendon and the presence of a patellar spur. The available standard pre-operative lateral radiographs were examined to see if a patellar spur was an indicator for rupture of the quadriceps tendon in this group of patients. Of the 107 patients, 12 underwent repair of a ruptured patellar tendon, 59 had an open reduction and internal fixation of a patellar fracture and 36 repair of a ruptured quadriceps tendon. In the 88 available lateral radiographs, patellar spurs were present significantly more commonly (p < 0.0005) in patients operated on for rupture of the quadriceps tendon (79%) than in patients with rupture of the patellar tendon (27%) or fracture of the patella (15%). In patients presenting with failure of the extensor mechanism of the knee in the presence of a patellar spur, rupture of the quadriceps tendon should be considered as a possible diagnosis

The Swansea Morriston Achilles Rupture Treatment (SMART) programme was introduced in 2008. This paper summarises the outcome of this programme. Patients with a rupture of the Achilles tendon treated in our unit follow a comprehensive management protocol that includes a dedicated Achilles clinic, ultrasound examination, the use of functional orthoses, early weight-bearing, an accelerated exercise regime and guidelines for return to work and sport. The choice of conservative or surgical treatment was based on ultrasound findings. . The rate of re-rupture, the outcome using the Achilles Tendon Total Rupture Score (ATRS) and the Achilles Tendon Repair Score, (AS), and the complications were recorded. An elementary cost analysis was also performed. . Between 2008 and 2014 a total of 273 patients presented with an acute rupture 211 of whom were managed conservatively and 62 had surgical repair. There were three re-ruptures (1.1%). There were 215 men and 58 women with a mean age of 46.5 years (20 to 86). Functional outcome was satisfactory. Mean ATRS and AS at four months was 53.0 (. sd . 14), 64.9 (. sd. 15) (n = 135), six months 67.8 (. sd. 16), 73.8 (. sd. 15) (n = 103) and nine months (72.4; . sd. 14) 72.3 (. sd. 13) (n = 43). The programme realised estimated cost savings exceeding £91 000 per annum. The SMART programme resulted in a low rate of re-rupture, a satisfactory outcome, a reduced rate of surgical intervention and a reduction in healthcare costs.

Aims. Functional rehabilitation has become an increasingly popular treatment for Achilles tendon rupture (ATR), providing comparably low re-rupture rates to surgery, while avoiding risks of surgical complications. Limited evidence exists on whether gap size should affect patient selection for this treatment option. The aim of this study was to assess if size of gap between ruptured tendon ends affects patient-reported outcome following ATR treated with functional rehabilitation. Methods. Analysis of prospectively collected data on all 131 patients diagnosed with ATR at Royal Berkshire Hospital, UK, from August 2016 to January 2019 and managed non-operatively was performed. Diagnosis was confirmed on all patients by dynamic ultrasound scanning and gap size measured with ankle in full plantarflexion. Functional rehabilitation using an established protocol was the preferred treatment. All non-operatively treated patients with completed Achilles Tendon Rupture Scores (ATRS) at a minimum of 12 months following injury were included. Results. In all, 82 patients with completed ATRS were included in the analysis. Their mean age was 51 years (standard deviation (SD) 14). The mean ATRS was 76 (SD 19) at a mean follow-up of 20 months (SD 11) following injury. Gap inversely affected ATRS with a Pearson’s correlation of -0.30 (p = 0.008). Mean ATRS was lower with gaps > 5 mm compared with ≤ 5 mm (73 (SD 21) vs 82 (SD 16); p = 0.031). Mean ATRS was lowest (70 (SD 23)) with gaps > 10 mm, with significant differences in perceived strength and pain. The overall re-rupture rate was two out of 131 (1.5%). Conclusion. Increasing gap size predicts lower patient-reported outcome, as measured by ATRS. Tendon gap > 5 mm may be a useful predictor in physically demanding individuals, and tendon gap > 10 mm for those with low physical demand. Further studies that control for gap size when comparing non-operative and operative treatment are required to assess if these patients may benefit from surgery, particularly when balanced against the surgical risks.

Aims. The aim of this systematic review and meta-analysis is to evaluate differences in functional outcomes and complications between single- (SI) and double-incision (DI) techniques for the treatment of distal biceps tendon rupture. Methods. A comprehensive search on PubMed, MEDLINE, Scopus, and Cochrane Central databases was conducted to identify studies reporting comparative results of the SI versus the DI approach. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used for search strategy. Of 606 titles, 13 studies met the inclusion criteria; methodological quality was assessed with the Newcastle-Ottawa scale. Random- and fixed-effects models were used to find differences in outcomes between the two surgical approaches. The range of motion (ROM) and the Disabilities of the Arm, Shoulder and Hand (DASH) scores, as well as neurological and non-neurological complications, were assessed. Results. A total of 2,622 patients were identified. No significant differences in DASH score were detected between the techniques. The SI approach showed significantly greater ROM in flexion (standardized mean difference (SMD) -0.508; 95% confidence interval (CI) -0.904 to -0.112) and pronation (SMD -0.325, 95% CI -0.637 to -0.012). The DI technique was associated with significantly less risk of lateral antebrachial cutaneous nerve damage (odds ratio (OR) 4.239, 95% CI 2.171 to 8.278), but no differences were found for other nerves evaluated. The SI group showed significantly fewer events of heterotopic ossification (OR 0.430, 95% CI 0.226 to 0.816) and a lower reoperation rate (OR 0.503, 95% CI 0.317 to 0.798). Conclusion. No significant differences in functional scores can be expected between the SI and DI approaches after distal biceps tendon repair. The SI approach showed greater flexion and pronation ROM and a lower risk of heterotopic ossification and reoperation. The DI approach was favourable in terms of lower risk of neurological complications. Cite this article: Bone Joint J 2020;102-B(12):1608–1617

We hypothesised that a minimally invasive peroneus brevis tendon transfer would be effective for the management of a chronic rupture of the Achilles tendon. In 17 patients (three women, 14 men) who underwent minimally invasive transfer and tenodesis of the peroneus brevis to the calcaneum, at a mean follow-up of 4.6 years (2 to 7) the modified Achilles tendon total rupture score (ATRS) was recorded and the maximum circumference of the calf of the operated and contralateral limbs was measured. The strength of isometric plantar flexion of the gastrocsoleus complex and of eversion of the ankle were measured bilaterally. Functional outcomes were classified according to the four-point Boyden scale. . At the latest review, the mean maximum circumference of the calf of the operated limb was not significantly different from the pre-operative mean value, (41.4 cm, 32 to 50 vs 40.6 cm, 33 to 46; p = 0.45), and not significantly less than that of the contralateral limb (43.1 cm, 35 to 52; p = 0.16). The mean peak torque (244.6 N, 125 to 367) and the strength of eversion of the operated ankle (149.1 N, 65 to 240) were significantly lower (p < 0.01) than those of the contralateral limb (mean peak torque 289, 145 to 419; strength of eversion: 175.2, 71 to 280). The mean ATRS significantly improved from 58 pre-operatively (35 to 68) to 91 (75 to 97; 95% confidence interval 85.3 to 93.2) at the time of final review. Of 13 patients who practised sport at the time of injury, ten still undertook recreational activities. . This procedure may be safely performed, is minimally invasive, and allows most patients to return to pre-injury sport and daily activities. Cite this article: Bone Joint J 2015;97-B:353–7

Disruption of the extensor mechanism in total knee arthroplasty may occur by tubercle avulsion, patellar or quadriceps tendon rupture, or patella fracture, and whether occurring intra-operatively or post-operatively can be difficult to manage and is associated with a significant rate of failure and associated complications. This surgery is frequently performed in compromised tissues, and repairs must frequently be protected with cerclage wiring and/or augmentation with local tendon (semi-tendinosis, gracilis) which may also be used to treat soft-tissue loss in the face of chronic disruption. Quadriceps rupture may be treated with conservative therapy if the patient retains active extension. Component loosening or loss of active extension of 20° or greater are clear indications for surgical treatment of patellar fracture. Acute patellar tendon disruption may be treated by primary repair. Chronic extensor failure is often complicated by tissue loss and retraction can be treated with medial gastrocnemius flaps, achilles tendon allografts, and complete extensor mechanism allografts. Attention to fixing the graft in full extension is mandatory to prevent severe extensor lag as the graft stretches out over time

Aims. To validate the Sydney Hamstring Origin Rupture Evaluation (SHORE), a hamstring-specific clinical assessment tool to evaluate patient outcomes following surgical treatment. Methods. A prospective study of 70 unilateral hamstring surgical repairs, with a mean age of 47.3 years (15 to 73). Patients completed the SHORE preoperatively and at six months post-surgery, and then completed both the SHORE and Perth Hamstring Assessment Tool (PHAT) at three years post-surgery. The SHORE questionnaire was validated through the evaluation of its psychometric properties, including; internal consistency, reproducibility, reliability, sensitivity to change, and ceiling effect. Construct validity was assessed using Pearson’s correlation analysis to examine the strength of association between the SHORE and the PHAT. Results. The SHORE demonstrated an excellent completion rate (100%), high internal consistency (Cronbach’s alpha 0.78), and good reproducibility (intraclass correlation coefficient (ICC) 0.82). The SHORE had a high correlation with the validated PHAT score. It was more sensitive in detecting clinical change compared to the PHAT. A ceiling effect was not present in the SHORE at six months; however, a ceiling effect was identified in both scores at three years post-surgery. Conclusion. This study has validated the SHORE patient reported outcome measure (PROM) as a short, practical, reliable, valid, and responsive tool that can be used to assess symptom and function following hamstring injury and surgical repair.

One of the factors that influence the outcome after rupture of the tendo Achillis is abnormality of gait. We prospectively assessed 14 patients and 15 normal control subjects using an in-shoe plantar pressure measurement system. There was a significant reduction in peak mean forefoot pressure in the early period of rehabilitation (p < 0.001). There was a concomitant rise in heel pressure on the injured side (p = 0.05). However, there was no difference in cadence, as determined by the duration of the terminal stance and pre-swing phases as a proportion of total stance. The forefoot pressure deficit in the group with tendon ruptures was smaller when assessed six months after the injury but was still significant (p = 0.029). Pedobarographic assessment confirms that there are marked abnormalities within the gait cycle. Rehabilitation programmes which address these abnormalities may improve outcome

Subcutaneous rupture of the tendon of tibialis anterior immediately proximal to its insertion affects patients over the age of 45 years and is most common in the seventh decade. The symptoms at the time of rupture are milder than is the case with rupture of the calcaneal tendon and the early disability is slight. Thus, affected patients commonly present several weeks or months after rupture and at a stage when reattachment of the tendon to its normal site of insertion (the most satisfactory surgical management) is impossible. Although the disability is slight if repair is not performed, there should be no disability after surgical repair and this should be offered to those patients who lead an active life and who present in the first three months after rupture. The relevant literature is reviewed and experience with four further patients is recounted

It has been suggested that an increased posterior tibial slope (PTS) and a narrow notch width index (NWI) increase the risk of anterior cruciate ligament (ACL) injury. The aim of this study was to establish why there are conflicting reports on their significance. A total of fifty patients with a ruptured ACL and 50 patients with an intact ACL were included in the study. The group with ACL rupture had a statistically significantly increased PTS (p < 0.001) and a smaller NWI (p < 0.001) than the control group. When a high PTS and/or a narrow NWI were defined as risk factors for an ACL rupture, 80% of patients had at least one risk factor present; only 24% had both factors present. In both groups the PTS was negatively correlated to the NWI (correlation coefficient = -0.28, p = 0.0052). Using a univariate model, PTS and NWI appear to be correlated to rupture of the ACL. Using a logistic regression model, the PTS (p = 0.006) and the NWI (p < 0.0001) remain significant risk factors. From these results, either a steep PTS or a narrow NWI predisposes an individual to ACL injury. Future studies should consider these factors in combination rather than in isolation

1. Twenty-two cases of synovial rupture of the knee have been studied. This condition may complicate any chronic synovitis of the knee in which a tense intra-articular effusion is subjected to increased tension during flexion and extension of the joint. 2. Two types of rupture have been seen; a herniation of the synovial membrane into the popliteal fossa and down the leg, and an acute synovial tear with extravasation of joint contents between the muscle planes of the calf. 3. The diagnosis of this condition, the differentiation of the types of rupture and their treatment are discussed. 4. The acute rupture usually responds to simple bed-rest; the large synovial herniations often need removal and repair of the posterior capsule

We report three complete ruptures and one partial rupture of the flexor pollicis longus tendon in association with the insertion of a volar plate for the treatment of fracture of the distal radius. Rupture was associated with the chronic use of steroids

1. Seventeen cases of knee injury are described in which the predominant lesion was rupture of the posterior cruciate ligament. Seven were treated conservatively and ten by surgical repair. 2. Most cases occurred in motor cyclists. 3. The extent of the rupture should be determined by examination under anaesthesia. 4. Early surgical repair is indicated for complete rupture. 5. An effective method of repair is described

1. The clinical aspects of fifty-six patients with rupture of the tendo calcaneus are discussed, and the mechanism of injury is described. 2. Operative repair of the rupture is considered with a study of the results in twenty-eight patients

1. Two cases of rupture of the axillary artery without dislocation of the shoulder or fracture of the neck of the humerus are reported, and the etiology is discussed. 2. The treatment of a ruptured axillary artery is primary repair, and not ligation. 3. In the repair of the artery the complete clearance of distal thrombus is most important; retrograde flushing is advised for this purpose

We performed two independent, randomised, controlled trials in order to assess the potential benefits of immediate weight-bearing mobilisation after rupture of the tendo Achillis. The first trial, on operatively-treated patients showed an improved functional outcome for patients mobilised fully weight-bearing after surgical repair. Two cases of re-rupture in the treatment group suggested that careful patient selection is required as patients need to follow a structured rehabilitation regimen. The second trial, on conservatively-treated patients, provided no evidence of a functional benefit from immediate weight-bearing mobilisation. However, the practical advantages of immediate weight-bearing did not predispose the patients to a higher complication rate. In particular, there was no evidence of tendon lengthening or a higher re-rupture rate. We would advocate immediate weight-bearing mobilisation for the rehabilitation of all patients with rupture of the tendo Achillis

Ochronosis, the musculoskeletal manifestation of alkaptonuria, is known to lead to degenerative changes of the spine and weight-bearing joints. Symptoms related to degeneration of tendons or ligaments with spontaneous ruptures have not previously been reported. Three patients are described with four spontaneous ruptures of either the patellar tendon or tendo Achillis as the first symptom of alkaptonuria

Controversy surrounds the most appropriate treatment method for patients with a rupture of the tendo Achillis. The aim of this study was to assess the long term rate of re-rupture following management with a non-operative functional protocol. . We report the outcome of 945 consecutive patients (949 tendons) diagnosed with a rupture of the tendo Achillis managed between 1996 and 2008. There were 255 female and 690 male patients with a mean age of 48.97 years (12 to 86). Delayed presentation was defined as establishing the diagnosis and commencing treatment more than two weeks after injury. The overall rate of re-rupture was 2.8% (27 re-ruptures), with a rate of 2.9% (25 re-ruptures) for those with an acute presentation and 2.7% (two re-ruptures) for those with delayed presentation. . This study of non-operative functional management of rupture of the tendo Achillis is the largest of its kind in the literature. Our rates of re-rupture are similar to, or better than, those published for operative treatment. We recommend our regime for patients of all ages and sporting demands, but it is essential that they adhere to the protocol

1. A case is reported of traumatic dislocation of the shoulder joint complicated by rupture of the axillary artery and vein and complete brachial plexus palsy. Whether the rupture occurred at the time of injury or during reduction is not known. 2. Despite a delay of five weeks before operative treatment was undertaken the usefulness of the arm was preserved. 3. After rupture of the axillary artery at this level an adequate collateral circulation is rapidly established in a healthy young adult. 4. The case illustrates the importance of careful examination of the peripheral nervous and vascular systems before and after reduction of a dislocated shoulder

Ten patients are reported who had sustained a partial rupture of the anterior cruciate ligament in a twisting injury of the knee. Nine of the 10 patients presented with a small effusion and pseudo-locking of the knee which was thought to be due to muscular spasm to prevent further ligamentous injury. The patients were examined clinically, under anaesthesia and by arthroscopy and the signs were found to be remarkably similar to those in patients with a tear of the medial meniscus. The mechanism of injury leading to partial rupture of the anterior cruciate ligament is discussed

We report the long-term results of the surgical treatment of chronic rupture of tendo Achillis using polyester tape. This requires minimal postoperative splintage and allows early mobilisation and a prompt return to work and sport. We reviewed 16 patients (10 women and 6 men) at a mean period of three years after surgery. The median time from injury to operation was 16.8 months (3.9 months to 13 years), and the median age of the patients was 52 years (27 to 78). The median time to full weight-bearing was 40 days and the median time for return to sport was 18 weeks (5.4 to 32). One patient required further surgery and one had numbness along the distribution of the sural nerve. After surgery only two patients had increased dorsiflexion of the ankle compared with the uninjured side. There were no cases of rerupture. We recommend this technique for the treatment of chronic rupture of tendo Achillis

We report ten cases of rupture of the distal part of the tendon of biceps brachii in patients aged from 27 to 58 years. MRI allowed assessment of the degree of retraction of the tendon which was related to the integrity of the bicipital expansion. When the retraction exceeded 8 cm the expansion was always ruptured. When there was doubt, or in longstanding injury, MRI allowed the lesions to be defined. Surgical repair was by reinsertion on the radial tuberosity at one or two fixation points in eight patients and reinsertion on the anterior brachial muscle in one. The other patient refused surgery. The MRI findings were confirmed at operation. Use of fixation points allowed minimal intervention, thereby reducing the risk of damaging the radial nerve. One year after operation, dynamometric evaluation of the strength of flexion and supination confirmed that the best results were obtained by reinsertion to the radial tuberosity

We randomised 50 patients with ankle fractures of Weber types B and C and a ruptured deltoid ligament treated by open reduction and internal fixation to two treatment groups to examine the influence of the repair of a ruptured deltoid ligament. No differences were found except for a longer duration of surgery in the repair group. Our findings suggest that a ruptured deltoid ligament can be left unexplored without any effect either on early mobilisation or on the long-term result

1. This case is presented to illustrate two etiological factors in tendon rupture occurring in one patient. 2. The rupture of the long head of the biceps brachii muscle appears to have been of acute traumatic origin. 3. Bilateral simultaneous rupture of the calcaneal tendons is rare, but it seems probable that the cortico-steroid therapy was the etiological factor in this case. 4. It has been suggested that degeneration in the tendon is caused by ischaemia, secondary to hypertrophy of the tunica media and narrowing of the medium calibre blood vessels. Betamethazone could possibly have aggravated, or may even have caused these changes, and the periarteriolar changes found in the biopsy specimen would tend to support this theory

In a study combining tissue mechanics and fracture morphology for the first time, we examined the ruptured surfaces of anterior cruciate ligaments of rabbits and related their appearance to the initial loading conditions. Sixteen specimens were stretched to failure at rates of displacement of 10 and 500 mm/min. We used video images to study the changes which occurred during the fracture process and SEM to examine the appearance of the ruptured surfaces. The surfaces of ligaments tested at 10 mm/min had more pulled-out collagen fibres and the fibres had more pronounced waviness compared with those tested at 500 mm/min. We have shown that the macroscopic appearance of ruptured ligaments can be related to their microscopic appearance and that it is possible to deduce whether failure was by gradual tearing of the fibres or catastrophic failure

We examined biopsy specimens obtained during surgery on 115 patients with complete rotator cuff rupture. The vascularised connective tissue covering the area of rupture and the proliferating cells in the fragmented tendons reflected more of the features of repair than of degeneration and necrosis. The main source of this fibrovascular tissue was the wall of the subacromial bursa. These features clearly indicated a vigorous reparative response which might play an important role in tendon reconstitution and remodelling. We therefore suggest that extensive debridement along with subtotal bursectomy, commonly practised during surgical repair of rotator cuff rupture, should be avoided. Although strong suture margins are essential for good operative results, debridement should be judicious and preserve as much as possible of the bursa and the associated fibrovascular tissue

The precise point of intradural rupture in preganglionic traction injuries to the brachial plexus has been a subject of controversy. In this study of avulsed roots we have shown that rupture occurs at varying levels. True avulsion of the root with attached spinal cord tissue was seen in two cases and in the remainder rupture was peripheral to the central-peripheral transition zone. We have further shown that corpora amylacea marked the boundary between tissue of the central and peripheral nervous systems. This observation provides a basis for renewed work towards the direct repair of intradural ruptures of the ventral and dorsal roots

We aimed to determine the distribution of the ABO and Rh blood groups in 832 patients with a tendon rupture. Among these, the frequency of blood group O (52.8%) was significantly higher than in the general population of Hungary (31.1%) and the frequency of group A was significantly lower. Of the 83 cases of multiple ruptures or re-rupture, 57 patients (68.7%) had group O blood. The dominance of group O was found for all sites of tendon rupture, but there was no significant association with the Rh groups. Individuals with blood group O appear to have an increased risk of tendon rupture

Rupture of the tendo Achillis is a common injury with a rising incidence. Traditionally the key question following this injury has been whether or not to operate. However a contemporary Cochrane review highlighted that the method of rehabilitation may also have an important contribution to the outcome. Since this review, various early weight-bearing rehabilitation protocols have been described. Currently evidence points to the use of early functional rehabilitation, regardless of operative or non-operative management. However, there is no consensus on which exact functional rehabilitation protocol should be used. Future research should be directed towards improving our understanding of how the different rehabilitative components interact in the tendo Achillis as it heals

We have reviewed 106 patients after treatment for spontaneous rupture of the calcaneal tendon, and assessed the clinical results including the power of plantarflexion. In patients treated within 48 hours of injury the result was very similar in conservatively and in operatively treated patients. The incidence of major complications was higher after operation (17%) than in those treated conservatively (4%). Patients who were treated more than one week after injury, however, had an inferior result with respect to power of plantarflexion after conservative management. It is therefore recommended that calcaneal tendon rupture is treated conservatively with a plaster in full equinus when it is diagnosed within 48 hours of injury, and by operation when diagnosis has been delayed for more than one week

The imaging techniques available to aid the diagnosis of ruptures of tendo Achillis, the rotator cuff and the tendon of tibialis posterior in rheumatoid patients are well described. However, ruptures of tendon or muscle at other sites are uncommon and may be overlooked. Diagnosis is often made by localised tenderness, swelling and a lack of active movement associated with a palpable defect. Clinical examination may be inconclusive and can be aided by imaging studies. We report two cases in which ruptures of a tendon were suspected, and ultrasound imaging demonstrated the palpable defect to be a cleavage plane in the subcutaneous fat – a ‘fat fracture’

The use of volar locking compression plates for the treatment of fractures of the distal radius is becoming increasingly popular because of the stable biomechanical construct, less soft-tissue disturbance and early mobilisation of the wrist. A few studies have reported complications such as rupture of flexor tendons. We describe three cases of rupture of extensor tendons after the use of volar locking compression plates. We recommend extreme care when drilling and placing the distal radial screws to prevent damaging the extensor tendons

1. A case of ossification and partial rupture of the tendo calcaneus is reported. 2. The possible etiology of the ossification and its relationship to the rupture is discussed

Aims

Acute distal biceps tendon repair reduces fatigue-related pain and minimizes loss of supination of the forearm and strength of flexion of the elbow. We report the short- and long-term outcome following repair using fixation with a cortical button techqniue.

While injury to the posterolateral corner is accepted as a relatively common occurrence associated with rupture of the anterior cruciate ligament, posteromedial meniscocapsular injury has not previously been recognised as such. In a prospective assessment of 183 consecutive reconstructions of the anterior cruciate ligament this injury was observed in 17 cases, giving it an incidence of 9.3%. Clinically, it was associated with a mild anteromedial rotatory subluxation and it is important not to confuse this with posterolateral rotatory subluxation. In no case was this injury identified by MRI. The possible long-term clinical relevance is discussed

Traumatic rupture of the tendon of the subscapularis muscle was documented as an isolated lesion in the shoulders of 16 men. The injury was caused either by forceful hyperextension or external rotation of the adducted arm. The patients complained of anterior shoulder pain and weakness of the arm when it was used above and below the shoulder level. They did not experience shoulder instability. The injured shoulders exhibited increased external rotation and decreased strength of internal rotation. A simple clinical manoeuvre called the 'lift-off test', reliably diagnosed or excluded clinically relevant rupture of the subscapularis tendon. Confirmation of the clinical diagnosis was best achieved by ultrasonography or MRI, but arthrography or CT arthrography were also useful. Surgical exploration confirmed the diagnosis in every case. Repair of the ruptured tendon was technically demanding and required good exposure to identify and protect the axillary nerve

Rupture of a ligament usually occurs along a definite line, but is associated with considerable intrinsic damage to the remote parts of the ligament. In spite of this, healing occurs by regeneration of regular collagen to form a new ligament with good tensile strength, provided the ends of the torn ligament are in reasonable apposition, and provided the blood supply is adequate. When lateral instability of the knee after a recent injury suggests that a collateral ligament has been ruptured, wide displacement of the torn ends should be suspected. Accurate replacement can be guaranteed only by surgical intervention; operative repair therefore seems to be justifiable on anatomical grounds. If operation is contemplated it should be undertaken within the first week after injury when it is easy to achieve accurate repair, which later becomes impossible because of shrinkage and friability of the tissue. In order to preserve blood supply, the areolar covering should be disturbed as little as possible, and the least possible amount of fine suture material should be used to anchor the torn ends in position. Nevertheless when the tear involves the upper attachment, ischaemia of the damaged ligament may prevent normal healing, whatever the treatment adopted

1. A case is described ofcomplete rupture ofthe second part of the axillary artery complicating anterior dislocation of the shoulder in a woman aged fifty years. 2. Interesting features were that the patient was comparatively young, that the rupture was a result of the dislocation and not of the reduction, that the axillary vein remained intact, and that a satisfactory circulation returned after ligation of the artery

A case of complete rupture of the axillary artery in a man aged eighty-seven is described. The injury occurred in connection with an antero-inferior dislocation of the shoulder. It is not known whether the rupture was caused by the dislocation itself or by the reduction. A successful suture of the artery was performed. A review of the literature is given, and earlier attempts to suture the artery in cases of this type are noted. The indications for this operation are discussed

We report the case of a 59-year-old man with severe knee pain and inability to flex his toes or invert his plantar flexed foot after an external rotation injury to his knee. MRI showed rupture of the popliteus with a haematoma compressing the neurovascular bundle in the proximal calf, and electromyography demonstrated signs of an axonotmesis of the posterior tibial nerve. There was progressive nerve recovery over 24 weeks. Isolated rupture of the popliteus should be considered in any patient with an acute haemarthrosis, lateral tenderness and a stable knee, especially after an external rotation injury

1. A case, believed to be the fifth on record, of supracondylar fracture with rupture of the brachial artery is described. 2. The relative immunity of the median nerve in these injuries is discussed, with brief reference to a recent case of complete rupture. Only a single previous report of this complication could be found. 3. It is suggested that these injuries are less uncommon than the number reported would indicate. 4. The anatomy of severe displacement is discussed, with special reference to the role of the brachialis. 5. The danger of closed reduction when the relationship of the upper fragment to the neurovascular bundle is in doubt is stressed. 6. The indications for open reduction are given

Closed rupture of the middle slip of the extensor hood of a finger is easily missed until the late appearance of a buttonhole deformity. Early diagnosis gives the best chance of satisfactory treatment, but Boyes' test becomes positive only at a late stage. A new test is described in which, from a 90 degree flexed position over the edge of a table, the patient tries to extend the proximal interphalangeal joint of the involved finger against resistance. The absence of extension force at the proximal joint and fixed extension at the distal joint are immediate signs of complete rupture of the central slip. The theoretical basis and the method of performing the test are discussed

1. Rupture of the brachial artery or of one of its divisions in association with elbow injuries is probably more common than a survey of the literature would imply. Three cases of rupture of the brachial artery complicating compound dislocation of the elbow are reported. 2. These cases appear to have a consistent pattern of soft-tissue damage, with avulsion of the common flexor origin, and a varying degree of damage to the biceps and brachialis. The median nerve escaped injury. 3. The method of dealing with the divided vessels does not appear to be of importance in determining the outcome, simple ligation being as satisfactory as attempts at grafting or suture. 4. In no case was there any evidence of Volkmann's contracture. Provided rapid reduction of the dislocation is effected, together with ligation of the vessels, a satisfactory return of the circulation may be expected

We reviewed 21 patients with 22 ruptures of the extensor pollicis longus at a mean of 5.3 years after transfer of the extensor indicis proprius tendon. Of these, 19 with 21 transfers described the result as good, and two as fair. The mean deficit of extension between the operated and unoperated thumbs was 1.4 cm, and the mean flexion deficit 0.6 cm. Pressure gauge measurements showed that the strength of the transfer was 51% of that of the uninjured extensor. The two fair results had an extensor lag of over 1.5 cm. Independent extension of the index was maintained in all patients, none having a discernible lag, but the strength of index extension was reduced to 49% of that of the normal finger. There was no evidence of functional loss. Extensor indicis proprius transfer for rupture of the extensor pollicis longus tendon is a simple and reliable procedure with few complications. It gives satisfactory long-term extension of the thumb

1. Forty-eight patients with spontaneous rupture of the tendon of the extensor pollicis longus have been studied and the results of forty-four operations by tendon transfer are reported. 2. The etiology and the pathology of the condition are discussed. 3. Transfer of the extensor indicis in general gives a better result than transfer of the extensor carpi radialis longus, but each method has its advantages and disadvantages. 4. The best results are obtained when the suture is done so as to leave the tendon in the fullest degree of tension obtainable

Thirty-three consecutive patients with complete ruptures of the calcaneal tendon were treated by external fixation. The patients were assessed both objectively and subjectively, and the results classified as excellent, good, fair and poor. In 30 patients the result was excellent or good. There were no infections or re-ruptures. Two patients with fair results had sural nerve injury. The only patient with a poor result had Sudeck's atrophy. It is felt that this operation satisfies the need for a new technique which is simple and combines the advantages of both surgical and non-surgical treatment without their major complications

Percutaneous repair of the ruptured tendo Achillis has a low rate of failure and negligible complications with the wound, but the sural nerve may be damaged. We describe a new technique which minimises the risk of injury to this nerve. The repair is carried out using three midline stab incisions over the posterior aspect of the tendon. A No. 1 nylon suture on a 90 mm cutting needle approximates the tendon with two box stitches. The procedure can be carried out under local anaesthesia. We reviewed 27 patients who had a percutaneous repair at a median interval of 35 months after the injury. They returned to work at four weeks and to sport at 16. One developed a minor wound infection and another complex regional pain syndrome type II. There were no injuries to the sural nerve or late reruptures. This technique is simple to undertake and has a low rate of complications

Four patients with pectoralis major ruptures underwent clinical and dynamometric assessment and one patient underwent late surgical repair. The operation is described. Dynamometry proved a useful and objective method of estimating the loss of strength and indicating patients who might benefit from surgical repair

1. Complete rupture of the axillary artery caused by dislocation of the shoulder in a man aged seventy-four is reported. There was severe arteriosclerosis and the simple operation of ligation of the artery was performed with success. There was excellent function of the shoulder and hand on review thirteen years later. 2. Previously recorded cases are reviewed

Ten cases of complete rupture of the collateral ligaments of the metacarpophalangeal finger joints are reported. The nature of this injury, the pre-operative morbidity and the intra-operative pathology are analysed. In all cases surgery was performed with satisfactory results. Operation is indicated for joint stability, grip and pinch strength, pain control and early functional recovery

The stress-tenogram is a radiological technique for the investigation of injuries to the lateral ligament of the ankle, and combines the information previously provided by inversion and anterior stress radiographs, and the peroneal tenogram. It is designed to differentiate between stable and unstable ankles, and between isolated ruptures of the anterior talofibular ligament and combined tears of the anterior talofibular and calcaneofibular ligaments. A high degree of diagnostic accuracy has been confirmed at operative repair in a group of thirty-two patients

A group of 40 patients with unstable knees due to a combination of a meniscal tear with a rupture of the anterior cruciate ligament was studied to assess the effects of treatment by meniscectomy alone. The results were assessed both subjectively and objectively, but emphasis was placed on the symptoms rather than the physical signs of instability. Meniscectomy alone cured the symptoms of instability in 22 of the patients and a further eight required no further surgical treatment; bucket-handle tears were associated with a good result and posterior-horn tears with a poor result. The remaining 10 patients later underwent an additional procedure to reconstruct the ligament because of persisting symptoms. It was concluded that in patients with this combined lesion the torn meniscus should be dealt with first. In young patients with a posterior-horn tear it would be justifiable to perform a ligamentous reconstruction at the same time as the meniscectomy

1. A case of bilateral spontaneous and simultaneous rupture of the quadriceps tendons is described. 2. The underlying cause was found to be gouty affection of the tendons. 3. So far as is known, a similar case has not previously been recorded

A total of 60 children and adolescents with rupture of the anterior cruciate ligament (ACL) was seen between 1980 and 1990. Observation of the 23 patients who were treated conservatively revealed that the natural history of the injury resulted in severe instability and poor function of the knee. Associated meniscal tears were present in 15 knees. Three osteochondral fractures occurred and osteoarthritic changes developed in ten knees. In 1990 therefore we introduced reconstruction of the ACL with a four-strand hamstring graft using an anatomical placement with transphyseal tunnels and anchorage well away from the growth plate. Over a period of nine years, 47 knees underwent reconstruction. The mean follow-up was 49 months (12 to 96). No child suffered physeal damage or leg-length discrepancy. The results were satisfactory in 77% and there was little difference between patients treated before the adolescent growth spurt and those treated during or after this time. These results, however, were not as good as those seen in adults during the same period

After a severe ankle sprain the incidence of residual complaints, particularly on the medial side of the joint, is high. We studied a consecutive series of 30 patients who had operative repair of acute ruptures of lateral ligaments. During operation, arthroscopy revealed a fresh injury to the articular cartilage in 20 ankles, in 19 at the tip and/or anterior distal part of the medial malleolus as well as on the opposite medial facet of the talus. In six patients, a loose piece of articular cartilage was found. We conclude that in patients with a rupture of one or more of the lateral ankle ligaments after an inversion injury, an impingement occurs between the medial malleolus and the medial facet of the talus. Patients with a lesion of the lateral ankle ligament caused by a high-velocity injury (a faulty landing during jumping or running) had a higher incidence of macroscopic cartilage damage (p < 0.01), medially-located pressure pain (p = 0.06) and medially-located complaints at one-year follow-up (p = 0.02) than those with a low-velocity injury (a stumble)

Consecutive patients with a confirmed rupture of at least one of the lateral ligaments of the ankle were randomly assigned to receive either operative or functional treatment. They were evaluated at a median of 8 years (6 to 11). In total, 370 patients were included. Follow-up was available for 317 (86%). Fewer patients allocated to operative treatment reported residual pain compared with those who had been allocated to functional treatment (16% versus 25%, RR 0.64, CI 041 to 1.0). Fewer surgically-treated patients reported symptoms of giving way (20% versus 32%, RR 0.62, CI 0.42 to 0.92) and recurrent sprains (22% versus 34%, RR 0.66, CI 0.45 to 0.94). The anterior drawer test was less frequently positive in surgically-treated patients (30% versus 54%, RR 0.54, CI 0.41 to 0.72). The median Povacz score was significantly higher in the operative group (26 versus 22, p < 0.001). Compared with functional treatment, operative treatment gives a better long-term outcome in terms of residual pain, recurrent sprains and stability

Aims

To determine whether the findings from a landmark Canadian trial assessing the optimal management of acute rupture of the Achilles tendon influenced the practice patterns of orthopaedic surgeons in Ontario, Canada.

Major ruptures of the rotator cuff were repaired in 89 patients over a six-year period, using an approach through the split deltoid muscle and the bed of the excised outer centimetre of the clavicle. Review of these patients showed that poor results were associated with larger cuff defects, with more pre-operative steroid injections and with pre-operative weakness of the deltoid muscle. A randomised prospective study showed that repair followed by splinting in abduction gave no better results than repair followed by resting the arm at the side. Excision of the coraco-acromial ligament was associated with worse results than leaving its divided halves in situ. Follow-up showed that the results continued to improve for two years after operation; their quality was maintained in patients less than 60 years old, but in those over 60 there was deterioration with time

Aims

The aim of the study was to analyze the results of primary tendon reinsertion in acute and chronic distal triceps tendon ruptures (DTTRs) in the general population.

Rupture of the tendons of both peroneus longus and peroneus brevis results in considerable disability. We have performed transfer of flexor digitorum longus (FDL) to peroneus brevis in two patients with lateral instability of the hindfoot due to chronic transverse tears of both tendons for which end-to-end repair was not possible. Both patients had excellent function when reviewed after eight and six years, respectively, with no symptoms. CT showed a normal appearance of the FDL in both patients, but the peroneal muscles looked abnormal. Transfer of the FDL provides a reliable solution to lateral instability of the hindfoot resulting from loss of function of both peronei

1. A clinico-pathological study of a patient who suffered traumatic rupture of his right popliteal artery is outlined. 2. Collateral circulation from the genicular anastomosis developed within twenty hours. 3. Ischaemic necrosis of the belly of the tibialis anterior occurred, but voluntary power began to return about twenty-one weeks after injury. 4. Biopsy of the muscle nineteen, fifty-seven and seventy-six weeks after injury showed that the muscle belly was being reconstituted by new fibres and that the ischaemic tissue remained entombed in the deepest part of the muscle. The regenerating fibres arose from small numbers of subfascial fibres which either survived the ischaemic episode or had arisen by myoblastic differentiation of connective tissue cells. Sarcoplasmic outgrowths produced new contractile substance, and new fibres were formed by amitotic fission. Many of the fibres matured and the regenerative process was still active seventy-six weeks after injury. 5. Growth of new nerve bundles containing myelinated axons accompanied the development of new muscle fibres

Five cases are presented of bilateral simultaneous rupture of the quadriceps tendon and the English literature of six isolated case reports is reviewed. All the patients were men, and most were over 50 years old. The injury often happens in elderly people and there is diagnostic confusion with other causes of inability to use the legs, notably with mild strokes. In three of our five cases there was a delay in diagnosis. The cardinal features are diffuse swelling around the knee, a visible or palpable suprapatellar defect and the inability to lift the straight leg despite a functioning quadriceps and normal activity in all other muscle groups in the leg. In all our patients operative repair was undertaken, followed by six weeks immobilisation in plaster and subsequent physiotherapy. Even late repair was associated with successful rehabilitation of the patient and a return to useful function

Forty patients with acute complete rupture of the calcaneal tendon were managed conservatively and randomly allocated to treatment groups using either cast immobilisation for eight weeks, or cast immobilisation for three weeks, followed by controlled early mobilisation in a Sheffield splint. The splint is an ankle-foot orthosis which holds the ankle in 15 degrees of plantar flexion, but allows some movement at the metatarsophalangeal joints. It is removed to allow controlled movement during physiotherapy. Patients treated with the splint regained mobility significantly more quickly (p less than 0.001) and preferred the splint to the plaster cast. The range of dorsiflexion at the ankle improved more rapidly after treatment in the splint (p less than 0.001), and patients were able to return to normal activities sooner. Recovery of the power of plantar flexion was similar in the two treatment groups, and no patient had excessive lengthening of the tendon. One re-rupture occurred in each group

Between 1993 and 1994, 891 patients underwent primary anterior cruciate ligament (ACL) reconstruction. A total of 48 patients had undergone bilateral ACL reconstruction and 42 were available for review. These patients were matched to a unilateral ACL reconstruction control group for gender, age, sport of primary injury, meniscal status and graft type. At 15-year follow-up a telephone interview with patients in both groups was performed. The incidence of further ACL injury was identified through structured questions and the two groups were compared for the variables of graft rupture or further ACL injury, family history of ACL injury, International Knee Documentation Committee (IKDC) subjective score and activity level.

There were 28 male and 14 female patients with a mean age of 25 years (13 to 42) at the time of first ACL injury. Subsequent further ACL injury was identified in ten patients (24%) in the bilateral ACL reconstruction study group and in nine patients (21%) in the unilateral ACL reconstruction control group (p = 0.794). The mean time from bilateral ACL reconstruction to further ACL injury was 54 months (6 to 103). There was no significant difference between the bilateral ACL reconstruction study group and the matched unilateral ACL reconstruction control group in incidence of further ACL injury (p = 0.794), family history of ACL injury (p = 0.595), IKDC activity level (p = 0.514), or IKDC subjective score (p = 0.824).

After bilateral ACL reconstruction the incidence of graft rupture and subjective outcomes were equivalent to that after unilateral ACL reconstructions.

We reviewed 5086 patients with a mean age of 30 years (9 to 69) undergoing primary reconstruction of the anterior cruciate ligament (ACL) in order to determine the incidence of secondary pathology with respect to the time between injury and reconstruction. There was an increasing incidence of medial meniscal tears and chondral damage, but not lateral meniscal tears, with increasing intervals before surgery. The chances of requiring medial meniscal surgery was increased by a factor of two if ACL reconstruction was delayed more than five months, and increased by a factor of six if surgery was delayed by > 12 months. The effect of delaying surgery on medial meniscal injury was also pronounced in the patients aged < 17 years, where a delay of five to 12 months doubled the odds of medial meniscal surgery (odds ratio (OR) 2.0, p = 0.001) and a delay of > 12 months quadrupled the odds (OR 4.3, p = 0.001). Increasing age was associated with a greater odds of chondral damage (OR 4.6, p = 0.001) and medial meniscal injury (OR 2.9, p = 0.001), but not lateral meniscal injury. The gender split (3251 men, 1835 women) revealed that males had a greater incidence of both lateral (34% (n = 1114) vs 20% (n = 364), p = 0.001) and medial meniscal tears (28% (n = 924) vs 25% (n = 457), p = 0.006), but not chondral damage (35% (n = 1152) vs 36% (n = 665), p = 0.565). We conclude that ideally, and particularly in younger patients, ACL reconstruction should not be delayed more than five months from injury.

Recent reports have suggested an increase in the number of anterior cruciate ligament (ACL) injuries in children, although their true incidence is unknown.

The prognosis of the ACL-deficient knee in young active individuals is poor because of secondary meniscal tears, persistent instability and early-onset osteoarthritis. The aim of surgical reconstruction is to provide stability while avoiding physeal injury. Techniques of reconstruction include transphyseal, extraphyseal or partial physeal sparing procedures.

In this paper we review the management of ACL tears in skeletally immature patients.

In a prospective study, 41 consecutive patients with a partial tear of the anterior cruciate ligament, diagnosed by arthroscopy, were reviewed after an average of 17 months, having been in plaster for six weeks after injury. Their average age was 29 years and review included clinical examination, measurement of anterior and posterior laxity with the Stryker knee laxity tester as well as evaluation of knee function and activity level. Twenty-one patients had unstable knees at follow-up; the mean total anteroposterior laxity for these patients was 12.6 +/- 3.9 mm compared with 7.1 +/- 4.3 mm for the normal knee. Most patients had few symptoms, but there was a significant reduction in the mean level of activity in the unstable group.

A new method of repair of the calcaneal tendon, which uses a small transverse skin incision, is described. In 41 patients, there was only one minor wound problem and the clinical results were satisfactory.

We report four children aged two to nine years with traumatic tears of the transverse ligament of the atlas and atlanto-axial subluxation. This is extremely rare in this age group since trauma usually causes a skeletal rather than a ligamentous injury. The injuries resulted from falls or motor vehicle accidents, with considerable delay in diagnosis. Flexion radiographs showed atlas-dens intervals (ADI) of 6, 7, 8 and 13 mm; all four patients were treated by posterior fusion at C1-C2 after the failure of conservative treatment. In one child with quadriparesis and a fixed ADI of 13 mm, transoral anterior resection of the odontoid was performed before the fusion. Diagnosis of this traumatic lesion requires a high level of suspicion. Conservative treatment is likely to fail; surgical stabilisation is indicated.

1. A case of disruption of patellar ligament is described.

2. An association with previous steroid infiltration is present in this case.

The results of 63 operative repairs of chronic tears of the rotator cuff in 61 patients are reviewed retrospectively; the mean follow-up was 32.7 months. Fifty-four patients presented with symptoms of persistent pain and seven patients with gross loss of movement. All the patients had failed to respond to conservative treatment. Results were assessed in terms of relief of pain, restoration of movement, the patients' ability to return to work and whether they were satisfied with the results. Overall, a good result in terms of relief of pain was achieved in 40 shoulders. In 31 shoulders (30 with pain and one without pain) the operation included particular measures to decompress the subacromial space; 26 of the patients achieved relief of pain which was significantly better than in those patients whose operation did not include a decompression. The complications and failures are discussed. It is suggested that operative repair of the chronically torn rotator cuff of the shoulder is a worthwhile operation and that the operation should include an adequate decompression of the subacromial space.

Failure of conservative treatment is the usual indication for the reconstruction of a knee with deficiency of the anterior cruciate ligament (ACL) and this depends on subjective judgement. The ability of muscles to protect the subluxing joint by reflex contraction could provide an objective measurement. We have studied 30 patients with unilateral ACL deficiency by measuring the latency of reflex hamstring contraction. We found that the mean latency in the injured leg was nearly twice that in the unaffected limb (99 ms and 53 ms respectively). There was a significant correlation between the differential latency and the frequency of 'giving way' indicating that functional instability may be due, in part, to loss of proprioception. Measures of proprioception, including reflex hamstring latency, may be useful in providing an objective assessment of the efficacy of conservative treatment and the need for surgery.

We reviewed 80 shoulders (77 patients) at a mean follow-up of 44 months after insertion of a Grammont inverted shoulder prosthesis. Three implants had failed and had been revised. The mean Constant score had increased from 22.6 points pre-operatively to 65.6 points at review. In 96% of these shoulders there was no or only minimal pain. The mean active forward elevation increased from 73° to 138°. The integrity of teres minor is essential for the recovery of external rotation and significantly influenced the Constant score. Five cases of aseptic loosening of the glenoid and seven of dissociation of the glenoid component were noted.

This study confirms the promising early results obtained with the inverted prosthesis in the treatment of a cuff-tear arthropathy. It should be considered in the treatment of osteoarthritis with a massive tear of the cuff but should be reserved for elderly patients.
