Aims. Complete ruptures of the ulnar collateral ligament (UCL) of the thumb are a common injury, yet little is known about their current management in the UK. The objective of this study was to assess the way complete UCL ruptures are managed in the UK. Methods. We carried out a multicentre, survey-based cross-sectional study in 37 UK centres over a 16-month period from June 2022 to September 2023. The survey results were analyzed descriptively. Results. A total of 37 centres participated, of which nine were tertiary referral hand centres and 28 were district general hospitals. There was a total of 112 respondents (69 surgeons and 43 hand therapists). The strongest influence on the decision to offer surgery was the lack of a firm ‘endpoint’ to stressing the metacarpophalangeal joint (MCPJ) in either full extension or with the MCPJ in 30° of flexion. There was variability in whether additional imaging was used in managing acute UCL injuries, with 46% routinely using additional imaging while 54% did not. The use of a bone anchor was by far the most common surgical option for reconstructing an acute ligament avulsion (97%, n = 67) with a transosseous suture used by 3% (n = 2). The most common duration of immobilization for those managed conservatively was six weeks (58%, n = 65) and four weeks (30%, n = 34). Most surgeons (87%, n = 60) and hand therapists (95%, n = 41) would consider randomizing patients with complete UCL ruptures in a future clinical trial. Conclusion. The management of complete UCL ruptures in the UK is highly variable in certain areas, and there is a willingness for clinical trials on this subject.

Abstract. Objectives. This study aims to evaluate the functional outcomes of early weight-bearing in a functional orthosis for conservatively managed, complete AT ruptures. Also we tried to evaluate the patient reported outcome with this form of treatment. Design. In this prospective study, we have analysed data from 41 patients with ultrasound diagnosed compete AT ruptures, with a gap of less than 5 cm. Every patient was treated in a functional weight-bearing orthosis (VACOped®) for 8 weeks with early weight-bearing following a specific treatment protocol, followed by rehabilitation with a trained physiotherapist. Methods. Patients were followed up with foot and ankle trained physiotherapist for at least 1 year post-injury. At final follow up, the followings were measured: calf girth, single-leg heel raise height and repetitions. Furthermore, ATRS score and a patient feedback were taken on this final visit. Result. The mean ATRS score was 82.1, with a re-rupture rate of only 2% as compared to 5% in normal orthosis. The average calf bulk difference was 1.6 cm, the average heel raise height difference was 1.8cm and a heel raise repetition difference of 6. There was a statistically significant correlation between ATRS score and calf muscle girth (p=0.02). However, there was no significant correlation between ATRS and heel raise height or heel raise repetitions. Conclusion. Early weight-bearing in a functional orthosis provides excellent functional outcomes for conservatively managed, complete AT ruptures, and is associated with very low re-rupture rates. A multidisciplinary approach with a guided rehabilitation programme is essential for optimising functional outcome

Purpose: The accurate preoperative evaluation of impingement syndrome and rotator cuff lesions, as well as the confirmation of the clinical and operative findings. Material-Method: 281 patients with clinical findings of impingement syndrome and/or lesions of the rotator cuff were evaluated with MRI. Results: The following MRI diagnoses were made: tendons’ lesions 306 (degeneration 138, complete rupture 116, partial rupture 52), impingement 196. The following RC lesions were in association with impingement syndrome: degenerative changes 106, complete rupture 101, incomplete rupture 48. The above mentioned tendon lesions were in many patients in all forms of degeneration (mixed). The dimention of all complete ruptures were measured on the MRI (116). In 93 patients of them operation followed. The MRI findings were confirmed in all patients except three (the operative findings showed 8,10,15 mms larger tears in comparison with the MRI measurements, 2, 4.5 and 5 months post-MRI examination respectively). Comparing the clinical and MRI findings we found agreement in 83.54%, unclear clinical diagnosis in 5.06%, partial agreement in 8.86% and disagreement in 2.53%. Conclusions: MRI is an excellent method in evaluating the rotator cuff lesions and those of the impingement syndrome as well as the extend and degree of muscle atrophy. More important though is the accurate evaluation of the extend and quality of RC lesions, which are closely related to the result of surgical intervention

Isolated rupture of short head of biceps is a rare injury. There have been no published reports of rupture at the musculotendinous junction. We report two cases of complete rupture of the musculotendinous junction of the short head of biceps in young males both occurring during water skiing. Two males sustained water skiing injuries where the handle was forced against the flexor region of the arm. Whilst trying to adduct and flex the extended arm, they both sustained complete musculotendinous ruptured of their short head of biceps. Both underwent pre-operative magnetic resonance imaging and one underwent isokinetic strength testing of elbow flexion and supination. Surgical repair was performed using absorbable sutures. One patient had the short head muscle belly flipped distally to lie in a subcutaneous plane in front of the elbow. Post-operative management included cast immobilisation for three weeks then gentle range of motion exercises. Both patients recovered their full range of motion in the arm. There were no complications. Post-operative strength testing was performed and will be presented. This is a unique series of complete musculotendinous rupture of the short head of biceps. The mechanism of injury was resisted adduction and flexion against the towrope handle with the arm in extension. These ruptures occurred in high impact high velocity accidents. Surgical repair lead to an excellent outcome

Hamstring muscle strain is a common sports related injury. It has been reported in a variety of sports, following acceleration or deceleration while running or jumping. Injury may vary from simple muscle strains to partial or complete rupture of the hamstring origin. Avulsion fracture of the ischial tuberosity has also been described. Simple hamstring muscle strains are treated conservatively. Surgical exploration and repair is currently advocated for partial or complete rupture of the hamstring origin. A few case series exists in literature suggesting the benefits of early intervention. We report a series of 8 athletes who presented between 2002 and 2006 with complete tear of their hamstring origin. Avulsion of the ischial tuberosity was excluded in these cases. After confirming the diagnosis, early surgical exploration and repair or reattachment was performed. The patients were braced for 8 weeks. This was followed by specialist physiotherapy and a supervised rehabilitation programme over 6 months. All patients were followed up to monitor return to normal activities and sports. The sciatic nerve was scarred to the avulsed tendon in three cases. Neurolysis led to a rapid relief of symptoms. Cases where the hamstring origin had retracted more than 3 cm required a figure 7 incision. There were no major complications including nerve palsies. An excellent functional outcome was noted by 12 months in all 8 patients. 7 of them returned to their previous level within 6-9 months of injury. One person despite a very good recovery, opted out of sports. No other complications were seen as a result of the surgical procedure. In conclusion, a tear of the origin of hamstring muscles is a significant injury. Early surgical repair and physiotherapy is associated with a good outcome and enables an early return to high level sports

Introduction. Autologous chondrocyte implantation (ACI) is contra-indicated in a joint rendered unstable by a ruptured anterior cruciate ligament (ACL). We present our experience of ACI repair with ACL reconstruction. Methods. Patients underwent arthroscopic examination and cartilage harvesting of the knee. A second operation was undertaken approximately six weeks later to repair the ruptured ACL with hamstring graft or Bone patella-Bone (BPB) and to implant the chondrocytes via formal arthrotomy. Three groups were assessed: Group 1: Simultaneous ACL Reconstruction and ACI; Group 2: Previous ACL Reconstruction with subsequent ACI repair; Group 3: Previously proven partial or complete ACL rupture, deemed stable and not treated with reconstruction with ACI procedure subsequently. Patients then underwent a graduated rehabilitation program and were reviewed using three functional measurements: Bentley functional scale, the modified Cincinnati rating system, and pain measured on a visual analogue scale. All patients also underwent formal clinical examination at review. Results. Those who underwent simultaneous ACL Reconstruction and ACI had a 47% improvement in Bentley functional scale, 36% improvement in visual analogue score and 38% improvement in the modified Cincinnati rating system. This is in contrast to only a 15% improvement in the modified Cincinnati rating system, 30% improvement in Bentley functional scale, and 32% improvement in visual analogue score in patients who had ACI repair after previous ACL reconstruction. 68% of patients who had the procedures simultaneously rated their outcome as excellent/good and 27% felt it was a failure. In contrast 38% of patients rated their outcome as a failure if they had ACI repair without reconstruction of ACL rupture. Conclusion. Symptomatic cartilage defects and ACL deficiency may co-exist in many patients and represent a treatment challenge. Our results suggest that a combined ACL and ACI repair is a viable option in this group of patients and should reduce the anaesthetic and operative risks of a two-stage repair. Patients with complete rupture of ACL despite being deemed stable performed poorly at review and our study suggests all complete ruptures regardless of stability should be treated with a reconstruction when performing an autologous chondrocyte implantation

Introduction. There is a challenge to detect partial tear of the ACL, the number of bundle injured and the proportion of fibers torn. The MRI was shown efficient to individualize the two anteromedial (AM) and posterolateral (PL) bundles of the ACL. The purpose of this study was to assess the ability of the MRI to detect partial tears of the ACL on axial views to display the AM and PL bundles. Materials and methods. This retrospective study included 48 patients (19 partial tears of the ACL, 16 complete rupture of the ACL and 13 normal knee) who underwent both arthroscopy and MRI examinations of the knee. The conventional MRI protocol included one sagittal T1- weighted sequence and 3 proton-density fat sat. The images from MRI were analysis by a radiologist specialized in musculoskeletal imaging who was blinding to the arthroscopic findings. The criteria for the analysis of MRI were divided into primary (those involving the ACL himself) and secondary signs (associated abnormalities). The primary signs included the horizontalisation of the ACL (ACL axis), the global ACL signal intensity and the signal intensity of each AM and PL bundle. The secondary signs included bone bruise, osteochondral impaction, popliteus muscle injury, medial collateral ligament injury and joint effusion. The ACL was classified as normal, partially or totally torn. The rupture of the AM and PL bundle was specified. Results. In our study, MRI was found to have a 75% sensitivity and a 73% specificity for the diagnosis of partial tears of the ACL. The sensitivity to detect AM bundle lesion was 88% but the specificity was 50%. The lack of horizontalisation of the ACL was a very good sign, for partial tears of the ACL, with a sensitivity of 84% and a specificity of 81% (p<0.05). Regarding the secondary signs, there was no significant difference to distinguish partial and complete tear. However, we found that there was a greater probability to find a partial tear of the ACL with the lack of joint effusion, bone bruise and medial collateral ligament injury. Quantifying the proportion of injured fibers was unsuccessful and was found as a failure of the MRI. Conclusions. MRI exhibited lower sensitivity and specificity for partial tear than for complete rupture of the ACL. However 3 important arguments can guide us: the lack of horizontalisation of the ACL, a continuous ACL signal, the display of one of two bundles on the axial view

Objectives. The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. Methods. A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review. Results. The treatments of acute Achilles tendon rupture include operative and nonoperative treatments. Operative treatments mainly consist of open repair, percutaneous repair, mini-open repair, and augmentative repair. Traditional open repair has lower re-rupture rates with higher risks of complications. Percutaneous repair and mini-open repair show similar re-rupture rates but lower overall complication rates when compared with open repair. Percutaneous repair requires vigilance against nerve damage. Functional rehabilitation combining protected weight-bearing and early controlled motion can effectively reduce re-rupture rates with satisfactory outcomes. Biological adjuncts help accelerating tendon healing by adhering rupture ends or releasing highly complex pools of signalling factors. Conclusion. The optimum treatment for complete rupture remains controversial. Both mini-open repair and functional protocols are attractive alternatives, while biotherapy is a potential future development.

Assessment of the appropriateness of tendon transfer procedures and the necessity for excising the posterior tibial tendon (PTT) in stage II PTT dysfunction. 12 patients undergoing surgical treatment for unilateral PTT dysfunction underwent magnetic resonance imaging of the tibialis posterior (TP) and flexor digitorum longus (FDL) muscle bellies. All patients had atrophy of the TP muscle compared to the normal leg (mean 10.7%, p = 0.008). In those patients with a complete rupture of PTT there was replacement of the TP muscle by fatty infiltration. Conversely, the FDL muscle showed a compensatory hypertrophy (mean 17.2%, p< 0.002). Treatment of stage II posterior tibial tendon (PTT) dysfunction remains controversial. These findings support the use of FDL as the tendon of choice for augmentation of PTT in stage II disease. This study also demonstrates that in the presence of a complete rupture, excision of the PTT is a reasonable surgical procedure and pure tenodesis will fail because the TP muscle belly undergoes fatty infiltration. In patients with a diseased but intact PTT there was no fatty infiltration and the TP muscle volume was at least 83% of the normal side in all cases. We therefore suggest that in the presence of an intact PTT the TP muscle may provide some useful function if used to augment the FDL transfer when the diseased tendon is excised

Aims

Avulsion of the proximal hamstring tendon origin can result in significant functional impairment, with surgical re-attachment of the tendons becoming an increasingly recognized treatment. The aim of this study was to assess the outcomes of surgical management of proximal hamstring tendon avulsions, and to compare the results between acute and chronic repairs, as well as between partial and complete injuries.

Summary. Nearly one-third of patients in this series with an ACL rupture requiring reconstruction had evidence of MPFL injury. This should be considered when patients are seen, and when MRI scans are reviewed/reported. Introduction. The Medial Patello-Femoral Ligament (MPFL) is the largest component of the medial parapatellar ligamentous complex. The senior surgeon felt that there was an anecdotally high rate of MPFL injury amongst his patients undergoing Anterior Cruciate Ligament (ACL) repair, but no discussion of this in the present literature. Method. A literature search was performed; although there were both scanty radiographic and anatomical studies of the MPFL, we found no literature looking at ACL and MPFL concurrent injury rates. The Magnetic Resonance Imaging (MRI) scans of fifty consecutive ACL reconstruction patients were retrospectively reviewed. Two independent radiologists were asked to review the scans looking specifically for evidence of MPFL rupture or Injury. The degree of injury was rated as rupture or by degree of sprain as applicable. One patient was excluded due to motion artefact limiting certainty. Results. Of the remaining forty-nine patients, 35 (71%) were intact, but fourteen (29%) showed evidence of injury. Five (10%) had a low-grade sprain, six (12%) had high-grade sprain, and three (6%) had complete rupture. The radiologists also noted that there was some variation in scanning protocols, and those with fat suppressed scans had better diagnostic value; this offered an opportunity to change the scanning practice. Conclusion. Nearly one-third of patients in this series with an ACL rupture requiring reconstruction had evidence of MPFL injury. This should be considered when patients are seen, and when MRI scans are reviewed/reported. Further, we would suggest that fat suppression sequences are included as standard to improve imaging quality

Knee dislocation is a rare injury in high energy trauma, but it is even rarer in low energy injuries. We present, to our knowledge, the only case in the world literature of knee dislocation following a cricketing injury. The patient was a 46 year old recreational fast bowler who, whilst bowling, slipped on the pitch on the follow through. He sustained an anteromedial knee dislocation which was reduced under intravenous sedation. He also sustained a neuropraxia of the common peroneal nerve with grade 2 weakness of ankle and toe dorsiflexion. Magnetic Resonance Imaging (MRI) confirmed a complete rupture of anterior cruciate ligament (ACL), lateral collateral ligament (LCL) and postero-lateral corner (PLC). Patient underwent surgical reconstruction and repair of his PLC along with repair of LCL with combination of anchor sutures and metal staple within 72 hours of the injury. He was treated in a cast brace. The ACL insufficiency was treated conservatively. Patient made an uneventful recovery and follow up at 3 months revealed a full range of knee movements with asymptomatic ACL laxity

Background. Acquired flatfoot deformity goes ahead with a partial or complete rupture and thus insufficiency of the tibialis posterior tendon. We present the results of flexor digitorum longus transfer and medial displacement calcaneal osteotomy to reconstruct the acquired deformity. Material & Methods. Twenty two patients (24 feet) with an average age of 58 (36–75) years were operated on for acquired flexible flatfoot deformity. Two patients had a bilateral procedure. Patients were seen pre-and postoperatively in order to evaluate following parameters: AOFAS hindfoot score, visual analogue scale for pain (0–10), the tarsometatarsal angle on lateral and ap standing x-rays, the cuneiform heights and talocalcaneal angle on lateral standing x-rays and subjective postoperative satisfaction score (1-worst to 5-best). Average time of follow-up was 24.7 months (12–48). Results. The AOFAS hindfoot score could be increased from 46.4 to 89.5 points, the visual analogue scale for pain decreased from 6.6 to 1.1. The average satisfaction score was 4.5 points with one patient scoring 2 and another one scoring 3. All the other patients scored either 4 or 5. All radiological parameters could be improved. Following complications were seen: one recurrence, two patients with irritation of the sural nerve, one patient with hypesthesia of the big toe. The calcaneal screws had to be removed in 3 patients. Conclusion. Flexor digitorum longus transfer together with medial displacement calcaneal osteotomy gave satisfactory results for the treatment of acquired flatfoot deformity. All radiologic parameters were improved

This is the largest detailed study of conservative management of Achilles tendon rupture in the literature to date. We assessed 140 subjects who had a complete rupture of their Achilles tendon treated with our combined conservative and orthotic regime between 1992 and 1998. Subjects were assessed subjectively and objectively, including isokinetic measurements of ankle plantarflexion and dorsiflexion. Overall 56% had excellent, 30% good, 12% fair and 2% poor results. The complication rate was 4%, with only 3 tendon reruptures. When compared with published results for operative repair, our combined conservative and orthotic treatment produces better results overall. Patients are subjectively happier, they have better strength results and have fewer complications

In Essex-Lopresti injuries, the prevailing concept, according to which the stability of the forearm can be restored after fixation of the fracture or replacement of the radial head by a metallic implant, is disputable. The aim of this study is to evaluate the midterm results in 12 patients with an Essex-Lopresti injury who were treated operatively. We studied 12 patients, with comminuted fracture of the radial head, either isolated (4 patients) or with injury of the ipsilateral (4 patients) or the contralateral (4 patients) arm. Initially, 10 patients were treated with excision of the radial head whereas 2 underwent internal fixation of the radial head and pinning of the DRUJ. Eventually, everyone developed a subluxation of DRUJ and had to be treated for an established Essex-Lopresti injury, 1–7 months after the initial injury. Six patients were treated with equalization of the radioulnar length (ulnar shortening osteotomy with or without a distractor-external fixator) and restoration of the TFC, while six patients underwent replacement of the radial head with a titanium implant, equalization of the radioulnar length and restoration of the TFC. The results were evaluated after a mean follow-up of 4 years (1–12 years), based on radiological and clinical criteria. The six patients in whom the titanium radial head implant was used presented with good results, even though two of them reported forearm pain during activity. On the contrary, in the rest of the patients the radioulnar incongruity reappeared in varying degrees. However the poor radiological result was not consistent to the clinical one. We conclude that in cases of complete rupture of the interosseous membrane, internal fixation or replacement of the radial head with a metallic implant will not probably provide us with a good long-term functional result

Aims: To determine the difference between macroscopic and microscopic appearances of the anterior cruciate ligament (ACL) in patients with osteoarthritis undergoing total knee replacement. Methods: Patients admitted for routine total knee replacement (TKR) for osteoarthritis were assessed. The integrity of the ACL was noted as normal, moderately damaged (fissured) or complete rupture on a macroscopic level at the time of surgery. The ACL was sacrificed as a normal step in the operation and sent for histological analysis. The macroscopic and microscopic findings of ACL histology were compared using a common grading system (Grade 1 = normal, Grade 2 = moderately diseased, Grade 3 = severely diseased). Results: The sample contained 48 patients, 17 male and 31 female, age range 55–87 years (mean 73). After exclusions, at surgery 7 ACL ruptures and 8 moderately diseased ligaments (defined by the presence of visible fissuring) were found despite negative pivot shift tests preoperatively. Of the 30 ACL’s that were found to be macroscopically normal, 22 of these (73%) were microscopically moderately or severely diseased. Conclusion: We have found that a macroscopically normal ACL does not necessarily equate to microscopic integrity in the presence of osteoarthritis. This is an important consideration given the current trend towards unicompartmental knee replacement and highlights the possible need for investigation with appropriate imaging (MRI) and arthroscopy prior to this specific surgery

Introduction: Acute Achilles tendon rupture is very much associated with sports practice and it’s a common lesion between young people. Despite of much Discussion: in the literature, the correct treatment of the complete ruptures of this tendon in the acute phase remains controversial. The objective of this work is to accomplish a comparative analysis between the results obtained with both techniques: open versus percutaneous. Materials and Methods: This work included 81 patients (6 women e 75 men) with acute rupture of the Achilles tendon between January of 1999 and December of 2008 and that were submitted 51 to surgical treatment with open technique and 30 with the percutaneous with the technique of Ma and Griffith modified. This patients had medium age of 35,6 years with a greater incidence between 30 and 39 years and with medium time follow-up of 1,9 years. The diagnostic of the lesion was based in clinic criteria and when there was a doubt an ecography was realized. In both Methods: was used posteoperative cast immobilization with 20° of plantar flexion during 6 weeks. The patients were analysed according to clinical e functional evaluations and the American Orthopaedic Foot and Ankle Society scale and the Holtz score. Results: The patients included in the percutaneous group had better functional results with more precocious weight bearing, better ankle range of movement e more earlier return to sports practice (p< 0,001). In the open technique there were more complications in comparison with the percutaneous one (15,7% vs 6,7%). In the open technique there were no rerupture and in the percutaneous technique there were 6. The results in both scales were better in the percutaneous group but it wasn’t statistically significative. Discussion: Good functional results and a low percentage of complications recommend the use of surgical techniques in the treatment of this disease. Better functional and aesthetic results were obtained in the percutaneous group but at expense of a more percentage of reruptures. Open surgery is indicated in the reruptures after the utilisation of the percutaneous technique

Don O’Donoghue (1950) described a particular acute injury of the knee in athletes (“also of high school age”) that he described as “an unhappy triad”. It consisted of: 1) rupture of the Medial Collateral Ligament (MCL), 2) damage to the Medial Meniscus (MM) and 3) rupture of the Anterior Cruciate Ligament (ACL). We have reviewed the arthroscopic findings of 34 consecutive knees (ages 12 to 16 years) with complete rupture of the ACL. In 21 cases the injury was acute, and the remaining were chronic of had had more than one traumatic episode at the time of arthroscopy. Out of the 34 cases, 26 had associated meniscal injuries: 4 MM; 14 Lateral Meniscus (LM) and 8 MM plus LM. Acute ACL injuries were associated mainly with LM damage (MM/LM: 1/5) whereas, in the chronic injuries, there were no such differences (MM/LM: 1/1). Out of the 21 acute LCA injuries there were 17 cases of acute rupture of the MCL. Conclusions: 1- Contrary to what has been widely accepted, also in pre-adolescent and adolescent, Acute ACL ruptures are more frequently associated with LM damage that with MM tears. 2- Most injuries of the MM associated to ACL injuries (particularly “bucket handle” tears) are the result of a previously ACL unstable knee

To investigate the diagnostic properties of magnetic resonance imaging (MRI) scans in detecting surgically verified disruptions of the cervical intervertebral disc and anterior (ALL) and posterior longitudinal (PLL) ligaments. Data were extracted from the reports of cervical spine MRI scans of patients who subsequently underwent surgical stabilization for presumed instability following disco-ligamentous injuries of the cervical spine. The level and severity of disc, ALL and PLL disruption was compared with surgical findings. Unweighted kappa statistics were used to assess agreement. The sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated after findings where dichotomised into complete rupture, yes/no. Sensitivity analyses were performed to account for missing data. The MRI and surgical findings were compared on 31 consecutive patients. The kappa values for intervertebral disc disruption, ALL and PLL disruption were 0.22, 0.25 and 0.31 respectively, indicating fair agreement. Sensitivity, specificity, PPV and NPV are shown in Table 1. The false negative rates for diagnosing complete disruption of the disc, ALL and PLL were 0.18, 0.40 and 0.14 respectively. The ability of cervical MRI scans to detect surgically verified disruptions of the intervertebral disc, ALL and PLL varied depending on the structure examined. In this series, the cervical MRI scan reliably detected disruption of the intervertebral disc disruption and ALL. The false negative rates are of concern and indicate the need for additional investigations to exclude instability in the absence of negative MRI findings

Introduction In this institution a structured program of conservative management of Achilles tendon rupture has been developed combining a conservative and orthotic treatment regime with a view to adding the advantages of a removable orthosis to traditional non-operative therapy. This study compares the results of this protocol to published surgical results. This is the largest detailed study of conservative management of Achilles tendon rupture in the literature to date. Methods We assessed 140 subjects who had a complete rupture of their Achilles tendon treated with our combined conservative and orthotic regime between 1992 and 1998. Subjective assessments of symptoms and objective measurements of ankle range of motion, calf circumference and isokinetic measurements of ankle plantar flexion and dorsi flexion were recorded. Patients also completed a functional heel-rise test. Our results have been compared to published series. Results Our overall results showed 56% had excellent, 30% good, 12% fair and two percent poor results. The overall complication rate was four percent, with three tendon reruptures. When compared with published results for operative repair, our combined conservative and orthotic treatment produces better results overall. Patients are subjectively happier, they have better strength results and have fewer complications.
