Aims. The aim of this study was to develop and internally validate a prognostic nomogram to predict the probability of gaining a functional range of motion (ROM ≥ 120°) after open arthrolysis of the elbow in patients with post-traumatic stiffness of the elbow. Methods. We developed the Shanghai Prediction Model for Elbow Stiffness Surgical Outcome (SPESSO) based on a dataset of 551 patients who underwent open arthrolysis of the elbow in four institutions. Demographic and clinical characteristics were collected from medical records. The least absolute shrinkage and selection operator regression model was used to optimize the selection of relevant features. Multivariable logistic regression analysis was used to build the SPESSO. Its prediction performance was evaluated using the concordance index (C-index) and a calibration graph. Internal validation was conducted using bootstrapping validation. Results. BMI, the duration of stiffness, the preoperative ROM, the preoperative intensity of pain, and grade of post-traumatic osteoarthritis of the elbow were identified as predictors of outcome and incorporated to construct the nomogram. SPESSO displayed good discrimination with a C-index of 0.73 (95% confidence interval 0.64 to 0.81). A high C-index value of 0.70 could still be reached in the interval validation. The calibration graph showed good agreement between the nomogram prediction and the outcome. Conclusion. The newly developed SPESSO is a valid and convenient model which can be used to predict the outcome of open arthrolysis of the elbow. It could assist clinicians in counselling patients regarding the choice and expectations of treatment. Cite this article: Bone Joint J 2022;104-B(4):486–494

Aims. Open reduction and plate fixation (ORPF) for displaced proximal humerus fractures can achieve reliably good long-term outcomes. However, a minority of patients have persistent pain and stiffness after surgery and may benefit from open arthrolysis, subacromial decompression, and removal of metalwork (ADROM). The long-term results of ADROM remain unknown; we aimed to assess outcomes of patients undergoing this procedure for stiffness following ORPF, and assess predictors of poor outcome. Methods. Between 1998 and 2018, 424 consecutive patients were treated with primary ORPF for proximal humerus fracture. ADROM was offered to symptomatic patients with a healed fracture at six months postoperatively. Patients were followed up retrospectively with demographic data, fracture characteristics, and complications recorded. Active range of motion (aROM), Oxford Shoulder Score (OSS), and EuroQol five-dimension three-level questionnaire (EQ-5D-3L) were recorded preoperatively and postoperatively. Results. A total of 138 patients underwent ADROM; 111 patients were available for long-term follow-up at a mean of 10.9 years (range 1 to 20). Mean age was 50.8 years (18 to 75);79 (57.2%) were female. Mean time from primary ORPF to ADROM was 11.9 months (6 to 19). Five patients developed superficial wound infection; ten developed symptomatic osteonecrosis/post-traumatic arthrosis (ON/PTA); four underwent revision arthrolysis. Median OSS improved from 17 (interquartile range (IQR) 12.0 to 22.0) preoperatively to 40.0 (IQR 31.5 to 48.0) postoperatively, and 39.0 (IQR 31.5 to 46.5) at long-term follow-up (p < 0.001). Median EQ-5D-3L improved from 0.079 (IQR -0.057 to 0.215) to 0.691 (IQR 0.441 to 0.941) postoperatively, and 0.701 (IQR 0.570 to 0.832) at long-term follow-up (p < 0.001). We found that aROM improved in all planes (p < 0.001). Among the variables assessed on multivariable analysis, a manual occupation, worsening Charlson Comorbidity Index and increasing socioeconomic deprivation were most consistently predictive of worse patient-reported outcome scores. Patients who subsequently developed ON/PTA reported significantly worse one-year and late OSS. Conclusion. ADROM in patients with persistent symptomatic stiffness following ORPF can achieve excellent short- and long-term outcomes. More deprived patients, those in a manual occupation, and those with worsening comorbidities have worse outcomes following ADROM. Cite this article: Bone Joint J 2022;104-B(1):157–167

Post-traumatic elbow stiffness is a disabling condition that remains challenging for upper limb surgeons. Open elbow arthrolysis is commonly used for the treatment of stiff elbow when conservative therapy has failed. Multiple questions commonly arise from surgeons who deal with this disease. These include whether the patient has post-traumatic stiff elbow, how to evaluate the problem, when surgery is appropriate, how to perform an excellent arthrolysis, what the optimal postoperative rehabilitation is, and how to prevent or reduce the incidence of complications. Following these questions, this review provides an update and overview of post-traumatic elbow stiffness with respect to the diagnosis, preoperative evaluation, arthrolysis strategies, postoperative rehabilitation, and prevention of complications, aiming to provide a complete diagnosis and treatment path.

Stiffness is an uncommon but potentially debilitating complication following total knee replacement (TKR). The treatment of this condition remains difficult and controversial. We present the results of 13 patients who underwent open arthrolysis for stiffness. The mean time between TKR and arthrolysis was 14 months. The mean follow-up was 7.2 years (2 to 10). The mean range of movement prior to arthrolysis was 55°. This increased to 91°, six months after arthrolysis (p < 0.005). The improved range of movement was maintained during the follow-up period. No patient has required revision of their components. We have found arthrolysis to be a useful and successful approach to post-TKR stiffness

We present a retrospective study of 25 patients treated by open arthrolysis of the elbow for post-traumatic stiffness. The mean follow-up was for 7.8 years (5 to 10.8). The range of movement of the elbow, pain scores and functional outcomes were recorded pre- and postoperatively. An improvement in the mean range of movement from 55° (0° to 95°) to 105° (55° to 135°) was obtained in our patients at one year. This improvement was maintained over the mean follow-up period of 7.8 years (5 to 10.8). Improvement in pain, function and patient satisfaction was recorded in 23 of the 25 patients at final follow-up. On the basis of this study, we believe that the results of open arthrolysis for post-traumatic stiffness of the elbow are durable over the medium term

The use of passive stretching of the elbow after arthrolysis is controversial. We report the results of open arthrolysis in 81 patients. Prospectively collected outcome data with a minimum follow-up of one year were analysed. All patients had sustained an intra-articular fracture initially and all procedures were performed by the same surgeon under continuous brachial plexus block anaesthesia and with continuous passive movement (CPM) used post-operatively for two to three days. CPM was used to maintain the movement achieved during surgery and passive stretching was not used at any time. A senior physiotherapist assessed all the patients at regular intervals. The mean range of movement (ROM) improved from 69° to 109° and the function and pain of the upper limb improved from 32 to 16 and from 20 to 10, as assessed by the Disabilities of the Arm Shoulder and Hand score and a visual analogue scale, respectively. The greatest improvement was obtained in the stiffest elbows: nine patients with a pre-operative ROM < 30° achieved a mean post-operative ROM of 92° (55° to 125°). This study demonstrates that in patients with a stiff elbow after injury, good results may be obtained after open elbow arthrolysis without using passive stretching during rehabilitation

Aims. This study aimed to determine the minimal detectable change (MDC), minimal clinically important difference (MCID), and substantial clinical benefit (SCB) under distribution- and anchor-based methods for the Mayo Elbow Performance Index (MEPI) and range of movement (ROM) after open elbow arthrolysis (OEA). We also assessed the proportion of patients who achieved MCID and SCB; and identified the factors associated with achieving MCID. Methods. A cohort of 265 patients treated by OEA were included. The MEPI and ROM were evaluated at baseline and at two-year follow-up. Distribution-based MDC was calculated with confidence intervals (CIs) reflecting 80% (MDC 80), 90% (MDC 90), and 95% (MDC 95) certainty, and MCID with changes from baseline to follow-up. Anchor-based MCID (anchored to somewhat satisfied) and SCB (very satisfied) were calculated using a five-level Likert satisfaction scale. Multivariate logistic regression of factors affecting MCID achievement was performed. Results. The MDC increased substantially based on selected CIs (MDC 80, MDC 90, and MDC 95), ranging from 5.0 to 7.6 points for the MEPI, and from 8.2° to 12.5° for ROM. The MCID of the MEPI were 8.3 points under distribution-based and 12.2 points under anchor-based methods; distribution- and anchor-based MCID of ROM were 14.1° and 25.0°. The SCB of the MEPI and ROM were 17.3 points and 43.4°, respectively. The proportion of the patients who attained anchor-based MCID for the MEPI and ROM were 74.0% and 94.7%, respectively; furthermore, 64.2% and 86.8% attained SCB. Non-dominant arm (p = 0.022), higher preoperative MEPI rating (p < 0.001), and postoperative visual analogue scale pain score (p < 0.001) were independent predictors of not achieving MCID for the MEPI, while atraumatic causes (p = 0.040) and higher preoperative ROM (p = 0.005) were independent risk factors for ROM. Conclusion. In patients undergoing OEA, the MCID for the increased MEPI is 12.2 points and 25° increased ROM. The SCB is 17.3 points and 43.3°, respectively. Future studies using the MEPI and ROM to assess OEA outcomes should report not only statistical significance but also clinical importance. Cite this article: Bone Joint J 2021;103-B(2):366–372

Aims. The rate of day-case total knee arthroplasty (TKA) in the UK is currently approximately 0.5%. Reducing length of stay allows orthopaedic providers to improve efficiency, increase operative throughput, and tackle the rising demand for joint arthroplasty surgery and the COVID-19-related backlog. Here, we report safe delivery of day-case TKA in an NHS trust via inpatient wards with no additional resources. Methods. Day-case TKAs, defined as patients discharged on the same calendar day as surgery, were retrospectively reviewed with a minimum follow-up of six months. Analysis of hospital and primary care records was performed to determine readmission and reattendance rates. Telephone interviews were conducted to determine patient satisfaction. Results. Since 2016, 301/7350 TKAs (4.1%) in 290 patients at our institution were discharged on the day of surgery. Mean follow-up was 31.4 months (6.2 to 70.0). In all, 28 patients (9.3%) attended the emergency department or other acute care settings within 90 days of surgery, most often with wound concerns or leg swelling; six patients (2.0%) were readmitted. No patients underwent a subsequent revision procedure, and there were no periprosthetic infections. Two patients (0.7%) underwent secondary patella resurfacing, and one patient underwent arthroscopic arthrolysis after previous manipulation under anaesthetic (MUA). Three patients (1.0%) underwent MUA alone. Primary care consultation records, available for 206 patients, showed 16 patients (7.8%) contacted their general practitioner within two weeks postoperatively; two (1.0%) were referred to secondary care. Overall, 115/121 patients (95%) telephoned stated they would have day-case TKA again. Conclusion. Day-case TKA can be safely delivered in the NHS with no additional resources. We found low incidence of contact with primary and secondary care in the postoperative period, and high patient satisfaction. Cite this article: Bone Jt Open 2023;4(8):621–627

Arthrolysis and dynamic splinting have been used in the treatment of elbow contractures, but there is no standardised protocol for treatment of severe contractures with an arc of flexion < 30°. We present our results of radical arthrolysis with twin incisions with the use of a monolateral hinged fixator to treat very severe extra-articular contracture of the elbow. This retrospective study included 26 patients (15 males and 11 females) with a mean age of 30 years (12 to 60). The mean duration of stiffness was 9.1 months (5.4 to 18) with mean follow-up of 5.2 years (3.5 to 9.4). The mean pre-operative arc of movement was 15.6° (0° to 30°), with mean pre-operative flexion of 64.1° (30° to 120°) and mean pre-operative extension of 52.1° (10° to 90°). Post-operatively the mean arc improved to 102.4° (60° to 135°), the mean flexion improved to 119.1° (90° to 140°) and mean extension improved to 16.8° (0° to 30°) (p < 0.001). The Mayo elbow score improved from a mean of 45 (30 to 65) to 89 (75 to 100) points, and 13 had excellent, nine had good, three had fair and one had a poor result. We had one case of severe instability and one wound dehiscence which responded well to treatment. One case had deep infection with poor results which responded well to treatment. Our findings indicate that this method is very effective in the treatment of severe elbow contracture; however, a randomised controlled study is necessary for further evaluation

The December 2013 Shoulder & Elbow Roundup. 360 . looks at: Platelet-rich plasma; Arthroscopic treatment of sternoclavicular joint osteoarthritis; Synchronous arthrolysis and cuff repair; Arthroscopic arthrolysis; Regional blockade in the beach chair; Recurrent instability; Avoiding iatrogenic nerve injury in elbow arthroscopy; and Complex reconstruction of total elbow revisions

Following arthroscopic arthrolysis for frozen shoulder, steroid injections may become necessary to improve ongoing pain and facilitate stretching exercises. The aim of this study was to evaluate the rate of steroid injections needed post-arthroscopic arthrolysis of frozen shoulder. Case series review carried out in a District General Hospital in UK. 30 consecutive patients who had arthroscopic arthrolysis under the care of the senior author were included. Patients’ records were analysed to identify the number of steroid injections administered post-operatively. 11 males and 19 females were examined, aged 46–83 years old (mean 56.1). 7 patients were diabetic. 10 patients (33.3%) received steroid injections post-operatively, with 8 of them receiving the injection within the first 6 post-operative months. The average post-operative time of steroid injection was 9.8 months. There was no association between diabetes and administration of a post-operative steroid injection P>0.01. Following arthroscopic arthrolysis a substantial proportion of patients may require one or more steroid injections to help pain and facilitate stretching exercises and physiotherapy. This study showed that 1 in 3 frozen shoulders treated with arthroscopic arthrolysis may need a subsequent steroid injection in the first year post surgery. Patients should be counselled preoperatively with regards to that, and be warned that arthroscopic arthrolysis is only the first step in the treatment pathway leading to recovery.

Abstract. Introduction. The rate of day-case total knee replacement (TKR) in the UK is currently ~0.5%. Reducing length of stay improves efficiency, increases operative throughput and tackles the rising demand for joint replacement surgery and the COVID-19 related backlog. We report safe delivery of day-case TKR in an NHS Trust via inpatient wards, with no additional resources. Methodology. Day-case TKRs, defined as patients discharged on the same calendar day as surgery, were retrospectively reviewed with a minimum follow-up of six-months. Analysis of hospital and primary care records was performed to determine readmission and reattendance rates. Telephone interviews were conducted to determine patient satisfaction. Results. Between 2016 and 2021, 301/7350 (4.1%) TKRs were discharged on the day of surgery. Mean follow-up was 31.4 (6.2–70.0) months. 28 (9.3%) patients attended Accident and Emergency or other acute care settings within 90-days of surgery; six (2.0%) patients were readmitted. No patients underwent a subsequent revision procedure. There were no prosthetic infections. Two patients underwent secondary patella resurfacing, and one patient underwent arthroscopic arthrolysis after previous manipulation under anaesthetic (MUA). Three patients underwent MUA alone. Primary care consultation records, available for 206 patients, showed 16 (7.8%) patients contacted their General Practitioner within two-weeks post-operatively; two (1.0%) were referred to secondary care. 115/121 (95%) patients telephoned stated they would have day-case TKR again. Conclusion. Day-case TKR can be safely delivered in the NHS with no additional resources. We found low incidence of contact with primary and secondary care in the post-operative period, and high patient satisfaction

Aims: The aims of this study were to define the incidence of knee stiffness following ACL reconstruction, to determine which patient factors were associated with this, and to assess how effective arthroscopic arthrolysis has been in treating the stiffness. Methods: To define the incidence of stiffness, we reviewed the patient records of a consecutive cohort of 100 primary isolated ACL reconstructions using quadruple hamstring autografts (2004–2006). Stiffness was defined as any loss of motion as compared to the contra-lateral leg. The mean age at reconstruction was 30 years and the median delay between injury and operation was 15 months. To assess the effectiveness of arthroscopic arthrolysis, we then reviewed all the patients who had undergone this procedure following primary isolated ACL reconstruction (n=18: 1997–2008). The mean age at arthrolysis was 31 years and the median delay between reconstruction and arthrolysis was nine months. Results: Following primary ACL reconstruction, the incidence of stiffness was 12% six months postoperatively. Poor compliance with physiotherapy (p< 0.005), previous knee surgery (p< 0.005), and anterior knee pain (p< 0.029) were significantly associated with stiffness. A binary logistic regression found both poor compliance with physiotherapy (Exp(B)=6.931; 95%CI, 1.609–29.859; p< 0.009) and previous knee surgery (Exp(B)=6.383; 95%CI, 1.548–26.322; p< 0.010) to be significant predictors of the stiffness. The rate of stiffness fell to 5% at 12 months, without operative intervention. Of the 18 patients who underwent arthroscopic arthrolysis, the mean extension loss improved from 7° to 1° and the mean flexion loss improved from 8° to 2°. Arthroscopic arthrolysis was significantly more effective in restoring extension loss (p< 0.029) if carried out within eight months of the primary reconstruction. Conclusions: Knee stiffness remains a significant problem post ACL reconstruction. This can however be effectively improved by appropriately timed arthroscopic arthrolysis

Abstract. Introduction. The incidence of significant acute chondral injuries with patella dislocation is around 10–15%. It is accepted that chondral procedures should only be performed in the presence of joint stability. Methodology. Patients were identified from surgeon/hospital logs. Patient demographics, lesion size and location, surgical procedure, patient reported outcome measures, post-operative MR imaging and complications were recorded. PROMs and patient satisfaction was obtained. Results. 20 knees (18 patients) were included. Mean age was 18.6 years (range; 11–39) and the mean follow-up was 16.6 months (range; 2–70). The defect locations were the lateral femoral condyle (9/20; 45%), patella (9/20; 45%), medial femoral condyle (1/20; 5%) and the trochlea (1/20; 5%). The mean defect size was 2.6cm2. Twelve knees were treated with cartilage fixation, 5 with microfracture and 3 with OATS. At follow up, the overall mean Lysholm score was 77.4 (± 17.1) with no chondral regenerative procedure being statistically superior. There was no difference in Lysholm scores between those patients having acute medial patellofemoral ligament reconstruction versus medial soft tissue plication (p=0.59). Five (25%) knees required re-operation (one arthroscopic arthrolysis; one patella chondroplasty; two removal of loose bodies; one implant adjustment). Overall 90% responded as being satisfied with surgery. Conclusion. Our aggressive pathway to identify and treat acute cartilage defects with early operative intervention and patella stabilisation has shown high rates of satisfaction and Lysholm scores with no major revisions. The full range of chondral restoration options should be considered by surgeons managing these patients

Introduction: Over the last decade there have been a series of papers, with a follow-up of less than 5 years, demonstrating the beneþcial effects of elbow arthrolysis. There are doubts about the durability of this procedure as most patients develop early arthritis of the elbow joint as a consequence of their injury, which, in theory, could reduce the range of movement in the joint. Aim: The aim of this study was to assess whether the improvement in the range of movement of the elbow achieved through arthrolysis changed in the postoperative period. Methods: This is a prospective study of 25 patients who had arthrolysis of the elbow performed to improve posttraumatic stiffness. All these patients had a minimum follow up period of 5 years. (Mean followup 8.2 years). Range of movement at the elbow was recorded using a goniometer. Functional outcomes and pain were also assessed at each of these visits using the Mayo elbow score and the visual analogue score. Results: Range of movement improved from 55 degrees preoperatively to 105 degrees postoperatively at 1 year and this improvement was maintained at their last followup. Similarly, the Mayo elbow score and visual analogue score also improved following an elbow arthrolysis and again this improvement was maintained at their last followup. Conclusions: Based on the results of this study, we believe that elbow arthrolysis for post traumatic stiffness of the elbow is a durable procedure

Abstract. Background. Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. Treatment needs to be customised to the patient taking into consideration injury to the knee; associated neurovascular and systemic injuries. Objective. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Methods. Seventy patients with knee dislocation were treated with multi-ligament reconstruction at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 3 weeks was preferred unless the patient was too unstable (Injury severity score>16). PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score. Results. The mean age of the patients was 35yrs (17–74), 53 males and 17 females. 5 patients had CPN injury (7%), 3 had vascular injury (4.2%), 2 had combined CPN and vascular injury (2.8%). Acute surgical treatment was done in 48 patients while 10 had staged reconstruction. 22 patients had delayed reconstruction. The mean follow-up period was 4.8 years (1–12 yrs). According to the IKDC score 67% of the patients had near-normal knee function. The mean Tegner activity scale postoperatively was 4.5 (preinjury 6.5) and the mean KOOS score was 75.3. Four patients had stiffness and needed arthroscopic arthrolysis, two patients had a residual foot drop from the original injury and needed tendon transfer. Conclusion. Traumatic knee dislocation is a challenging problem but good outcomes can be achieved by surgical management

Aim. Over the last 15 years there has been a series of publications reporting the beneficial effects of elbow arthrolysis, with considerable variation in operative technique and post-operative management. Many advocate the use of passive stretching techniques in the early post-operative period if range of motion fails to improve satisfactorily. The purpose of this study was to assess our results of open elbow arthrolysis in patients who did not receive any passive stretching after discharge from hospital. Methods. Prospectively collected data of 55 patients with a minimum follow-up of 1 year after arthrolysis were analysed. All procedures were performed by the same surgeon (LR), achieving as much improvement in elbow motion as possible at operation. All patients had continuous brachial plexus blocks and continual passive motion for 2-3 days post-operatively but none received any passive stretching after discharge. At review, a senior physiotherapist (BD) formally assessed all the patients. Results. All patients' arc of movement improved from 68 degrees to 104 degrees (flexion 18 degrees/extension 23 degrees). Upper limb function (Disabilities of the Arm, Shoulder and Hand score) improved by 50%. Pain decreased from 20 to 9, measured with a Visual Analogue Score. The greatest improvement in motion was obtained in the stiffest elbows - 7 patients with an arc of 30 degrees or less pre-operatively achieved an arc of 100 degrees by the time of the last review. Conclusions. Good results of open arthrolysis for post-traumatic elbow stiffness can be achieved with continuous brachial plexus blocks and continual passive motion for 2-3 days post-operatively. There appears to be little evidence to support treatment with passive stretching techniques after discharge from hospital, as our results are similar to other reported series

Previous studies have demonstrated the benefits of arthroscopic arthrolysis in relieving pain and improving motion in arthritic elbows, but none have reported the specific functional recovery. This study aims to review the functional outcome and patient satisfaction in a series of patients who underwent arthroscopic elbow arthrolysis for intrinsic stiffness, pain and arthritis not suitable for arthroplasty. Twenty six patients who underwent arthroscopic arthrolysis over a three year period were included. All patients were manual workers or strength athletes. All had pain and stiffness secondary to primary or secondary arthritis, with or without loose bodies. Pre- and post-operative evaluation included the Elbow Functional Assessment score, patient satisfaction and return to work and sports. The mean follow up period was 22 months. Function improved significantly in 87% with overall improvement in the Elbow Functional Assessment score from a preoperative score of 48 to a postoperative score of 84 (p< 0.05). All except three patients returned to their desired level of activity by 3 months postoperatively. Pain improved in 91%, mechanical symptoms in 80%, stiffness in all except one. The arc of elbow movement improved from 106° to 124° with a mean gain in elbow extension of 13°. Mayo elbow performance index also significantly improved postoperatively. Overall, 87% patients were very satisfied with the outcome. We conclude that the arthroscopic arthrolysis improves elbow function and returns patients to their desired level of activity, as well as improving range of motion and pain in patients with intrinsic elbow stiffness and pain

Over the last 15 years there have been a series of publications reporting the beneficial effects of elbow arthrolysis, with considerable variation in operative technique and post-operative management. Aim. To assess the results of open elbow arthrolysis in patients who did not receive any physiotherapy after discharge from hospital, although this is routinely prescribed by many surgeons. Patients and Methods. Prospectively collected data of 34 patients with a minimum follow-up of 1 year after arthrolysis was analysed. All the procedures were performed by the same surgeon, achieving as much improvement in elbow motion as possible at operation. All the patients had continuous brachial plexus blocks and continual passive motion for 2–3 days postoperatively but none received any physiotherapy after discharge. At review, a senior physiotherapist formally assessed all the patients, including measuring elbow motion with a goniometer. Results. All patients’ arc of movement improved from, with mean elbow flexion increasing by 16 degrees and extension 20 degress at the last follow-up. Upper limb function, assessed with a Disabilities of the Arm, Shoulder and Hand score (DASH), had improved 30%. Pain had decreased from 4.8 to 3.1 using the Visual Analogue Score. The greatest improvement in motion was obtained in the stiffest elbows – 5 patients with an arc of 30 degrees or less pre-operatively achieved an arc of 96 degrees by the time of the last review. Only early complications occurred – ulnar neuritis and significant pain – but these symptoms had largely settled by the time of the last review. Conclusions. Good results of open arthrolysis for post-traumatic elbow stiffness can be achieved with continuous brachial plexus blocks and continual passive motion for 2–3 days post-operatively. There appears to be little evidence to support formal treatment with physiotherapy after discharge from hospital, as our results are similar to other reported series

Introduction and Aims: The aim of this study was to assess the results of open elbow arthrolysis for post-traumatic stiffness. Method: This is a prospective study of 89 patients (M: F 53:36) with a mean age of 34 years. All patients had open elbow arthrolysis followed by continuous passive motion (CPM) for 72 hours. CPM was facilitated by analgesia in the form of a continuous brachial plexus block. After CPM patients were advised to actively mobilise their elbow. The minimum follow-up was one year. (Mean follow-up 47 months). Range of movement (ROM) was recorded using a goniometer; function was assessed using the mayo score and pain using the visual analogue score. Results: ROM improved from 60.9 to 104.2 degrees, flexion improved from 119.8 to 136.3 and extension improved from 58.9 to 32.1 degrees. Pain improved from 4.8 to 3.1 and the Mayo score improved from 60 to 85. In the sub-group of 25 patients with severe stiffness (pre-operative arc < 50 degrees), ROM improved from 29.6 to 89 degrees. Flexion improved from 99.2 to 132.2 degrees, extension improved 70 to 43.2 degrees. Pain improved from 5.6 to 4.0 and the Mayo score improved from 40 to 75. In the sub-group of 29 patients with a minimum follow-up of five years, ROM improved from 57.7 to 104.3 degrees at the year one post-operative assessment. ROM was maintained at their last follow-up, measuring 108.6 degrees. The pain score improved from 4.3 to 2.8 and was at 2.7 at their last follow-up. The Mayo score improved from 65 to 85 at year one, which was maintained at their last follow-up. Conclusion: Open elbow arthrolysis for post-traumatic stiffness of the elbow is a durable procedure for improving ROM and function. Moreover the results of elbow arthrolysis are not influenced by the degree of pre-operative stiffness
