Supraspinatus muscle atrophy in relation to aging with or without shoulder pathology: A radiographic study.

Introduction: Supraspinatus muscle atrophy is commonly associated with shoulder disease, but the effect of ageing on atrophy is not well understood. It was the aim of this study to investigate this effect using MRI scans in older patients. Methods and materials: A retrospective review of MRI scans in patients aged >70 years was performed between Jan 2016-Dec 2018.Both normal and abnormal scans were included in the analysis which included quantifying muscle atrophy of the supraspinatus using Thomazeu's occupation ratio. Results: There were 39 normal shoulder MRI scans with a mean age of 75 years (range: 70-88) and 163 abnormal scans with a mean age of 77 years (range: 70-93). The mean supraspinatus occupation ratio for normal MRI scans was 0.57 (range: 0.33-0.86) and abnormal scans 0.35 (range: 0.17-0.90). Occupation ratio was maintained with advancing until the age of 85 years before undergoing a significant declin following this. Conclusion: This study has shown that the occupation ratio is significantly reduced with shoulder disease, but normal shoulders do not undergo significant atrophy of supraspinatus tendon with increasing age. An occupation ratio of <0.32 is unlikely to occur in normal shoulders and this awareness may be useful when planning shoulder surgery, specifically shoulder arthroplasty.

Use of patient reported experience measure and patient reported outcome measures to evaluate differences in surgical or non-surgical management of humeral shaft fractures.

Background: The aim of this study was to evaluate the use of patient reported experience measures (PREMs) in humeral shaft fractures managed with or without surgery against patient reported outcome measures (PROMs). Methods: Adult patients treated for a humeral shaft fracture between June 2015 and August 2017 were included in non-surgery and surgery (early and late surgery) groups. The PREM questionnaire was based on patient and clinician feedback obtained during focus groups and was posted to patients. PROMs included the short form-12 (SF-12) and visual analogue scale (VAS) for pain, stiffness, function and satisfaction. Results: Eighty-one patients responded, 54 patients were treated in a brace and 27 with surgery (13 early, 14 late). There was moderate positive correlation between PREM and VAS satisfaction and function and moderate negative correlation with VAS pain and stiffness. There was also moderate positive correlation between PREM and SF-12 mental and weak positive correlation with SF-12 physical. The late surgery group had poorer PREMs (expectations, p = 0.002 and friends & family test, p = 0.0001) and PROMs (VAS satisfaction, p = 0.005) compared to the early surgery group. Conclusions: PREMs can be used in conjunction with PROMs to improve the patient's quality of care and as a means of identifying, at an early stage, those patients not doing well and to offer surgery.

Elbow conditions: research priorities setting in partnership with the James Lind Alliance.

OBJECTIVE: To undertake a UK-based James Lind Alliance (JLA) Priority Setting Partnership for elbow conditions and be representative of the views of patients, carers and healthcare professionals (HCPs). SETTING: This was a national collaborative study organised through the British Elbow and Shoulder Society. PARTICIPANTS: Adult patients, carers and HCPs who have managed or experienced elbow conditions, their carers and HCPs in the UK involved in managing of elbow conditions. METHODS: The rigorous JLA priority setting methodology was followed. Electronic and paper scoping surveys were distributed to identify potential research priority questions (RPQs). Initial responses were reviewed and a literature search was performed to cross-check categorised questions. Those questions already sufficiently answered were excluded and the remaining questions were ranked in a second survey according to priority for future elbow conditions research. Using the JLA methodology, responses from HCP and patients were combined to create a list of the top 18 questions. These were further reviewed in a dedicated multistakeholder workshop where the top 10 RPQs were agreed by consensus. RESULTS: The process was completed over 24 months. The initial survey resulted in 467 questions from 165 respondents (73% HCPs and 27% patients/carers). These questions were reviewed and combined into 46 summary topics comprising: tendinopathy, distal biceps pathology, arthritis, stiffness, trauma, arthroplasty and cubital tunnel syndrome. The second (interim prioritisation) survey had 250 respondents (72% HCP and 28% patients/carers). The top 18 ranked questions from this survey were taken to the final workshop where a consensus was reached on the top 10 RPQs. CONCLUSIONS: The top 10 RPQs highlight areas of importance that currently lack sufficient evidence to guide diagnosis, treatment and rehabilitation of elbow conditions. This collaborative process will guide researchers and funders regarding the topics that should receive most future attention and benefit patients and HCPs.

The management of displaced humeral shaft fractures - A survey of UK shoulder and elbow surgeons.

Introduction: Indications for surgical management of displaced humeral shaft fractures are not clearly established, leading to variations in practice. The aim of this study was to determine the scale of these variations in the UK practice to help design a future national trial. Methods: An online survey was sent to all surgeon members of British Elbow and Shoulder Society to help define humeral shaft fractures, fracture displacement as well as indications for operative and non-operative management. Patient and injury related factors considered important when managing humeral shaft fractures were investigated. Results: The survey achieved a response rate of 32% (104/327). There was a lack of consensus on definitions for humeral shaft fractures and fracture displacement. A functional brace was the most common form of non-operative treatment (63%). Majority immobilise humeral shaft fractures for 4-8 weeks or until callus are visible (62%) with a similar number considering operative treatment if adequate signs of healing are not present at around 12-16 weeks. Around half of our respondents exclusively use plates with variations in preference of approach and a minority (2%) exclusively use intra-medullary nails. Conclusion: The significant variation in management of displaced humeral shaft fractures in the UK suggests a clear need to evaluate clinical and cost effectiveness through a multi-centre randomised trial.

Interposition GraftJacket allografts for irreparable rotator cuff tears.

AIMS: Long-term outcomes following the use of human dermal allografts in the treatment of symptomatic irreparable rotator cuff tears are not known. The aim of this study was to evaluate these outcomes, and to investigate whether this would be a good form of treatment in young patients in whom a reverse shoulder arthroplasty should ideally be avoided. METHODS: This prospective study included 47 shoulders in 45 patients who underwent an open reconstruction of the rotator cuff using an interposition GraftJacket allograft to bridge irreparable cuff tears, between January 2007 and November 2011. The Oxford Shoulder Score (OSS), pain score, and range of motion (ROM) were recorded preoperatively and at one year and a mean of 9.1 years (7.0 to 12.5) postoperatively. RESULTS: There was significant improvement in the mean OSS from 24.7 (SD 5.4) preoperatively to 42.0 (SD 6.3) at one year, and this improvement was maintained at 9.1 years (p < 0.001), with a score of 42.8 (SD 6.8). Similar significant improvements in the pain score were seen and maintained at the final follow-up from 6.1 (SD 1.6) to 2.1 (SD 2.3) (p < 0.001). There were also significant improvements in the ROM of the shoulder, and patient satisfaction was high. CONCLUSION: The use of an interposition human dermal allograft in patients with an irreparable rotator cuff tear leads to good outcomes that are maintained at a mean of nine years postoperatively.

Early versus delayed repair of traumatic rotator cuff tears. Does timing matter on outcomes?

INTRODUCTION: The purpose of this study was to determine if delay (before or after 4 months) in repairing a symptomatic traumatic rotator cuff tear affected clinical outcome, re-rupture rates and use of interpositional dermal grafts. METHODS: This was a case matched (age + tear size) series of patients who underwent an early (≤ 4 months) or delayed (> 4 months) rotator cuff repair following a traumatic tear. If a direct repair could not be achieved a dermal interposition graft was used. Outcomes were collected at a median time of 30 months post-operatively using the Oxford, Constant and EQ5D scores. RESULTS: Twenty patients underwent rotator cuff repair within 4 months (1-4) of injury. Twenty age and cuff tear size-matched patients were identified who had undergone a delayed repair (4.1-24 months) after injury. We found no significant difference (p > 0.05) in patient reported outcomes scores between the early and delayed repair. [Oxford scores; Early 43(13-48), Delayed 45 (31-48); Constant scores; Early 73 (21-94), Delayed 73.5 (44-87); EQ5D; Early 0.75 (0.25-1), Delayed 0.77 (0.4-1)]. Time to full recovery was significantly longer (14 vs 33.8 months) for the delayed repair group (P > 0.05). When cuff tears were subdivided into < 3 cm tears or ≥ 3 cm tears, no significant difference outcome scores were founds. However, use of dermal interposition graft was 44% in delayed group for tears ≥ 3 cm. No grafts were used in early repair group. There was one symptomatic re-tear in our series which was in the early repair group. CONCLUSION: When compared to the delayed repair group, patients that underwent early repair of traumatic rotator cuff tears had shorter time of recovery, and less need for allograft augmentation for tears 3 cm or greater. However, at mid-term follow-up, this study found no difference in patient reported outcomes following early versus delayed repair of traumatic rotator cuff tears. LEVEL OF EVIDENCE: 3.

Floor and ceiling effects in the Oxford Shoulder Score : an analysis from the National Joint Registry.

AIMS: The main objective of this study was to examine whether the Oxford Shoulder Score (OSS) demonstrated floor or ceiling effects when used to measure outcomes following shoulder arthroplasty in a large national cohort. Secondary objectives were to assess its pain and function subscales, and to identify independent predictors for patients achieving a postoperative ceiling score following shoulder arthroplasty. METHODS: Secondary database analysis of the National Joint Registry (NJR), which included 48,270 patients undergoing shoulder arthroplasty, was conducted. The primary outcome measure was the OSS. Secondary outcome measures were the OSS-Function Component Subscale and OSS-Pain Component Subscale. Floor and ceiling effects were considered to be present if > 15% of patients scored either the lowest or highest possible score. Logistic regression analysis was used to identify independent predictors for scoring the highest possible OSS score postoperatively. RESULTS: Preoperatively, 1% of patients achieved the lowest possible OSS score (0) and 0.4% of patients achieved the highest possible score (48). Postoperatively, < 1% of patients achieved the lowest score at all timepoints, but the percentage achieving the highest score at six months was 8.3%, at three years 16.9%, and at five years 17%. Male patients, those aged between 60 and 89 years, and those undergoing an anatomical total shoulder arthroplasty (ATSA) were more likely to contribute to the ceiling effect seen in the OSS questionnaire. Pain and function subscales exhibited greater ceiling effects at three years and five years when compared with the overall OSS questionnaire. Logistic regression analysis showed that sex, procedure type, and preoperative OSS score were independent predictors for scoring the highest possible OSS at years. CONCLUSION: Based on NJR patient-reported outcome measures data, the OSS does not exhibit a ceiling effect at six months, but does at three years and five years, in part due to outcome scores of ATSA. Preoperative OSS, age, male sex, and ATSA are independent predictors of achieving a ceiling score. Cite this article: Bone Joint J 2021;103-B(11):1717-1724.

Treatment of massive irreparable rotator cuff tears using dermal allograft bridging reconstruction.

AIMS: Various options are available for treating massive irreparable rotator cuff tears, but all have their own limitations and no gold standard currently exists. Our aim was to report on outcomes of bridging repair with a dermal allograft for symptomatic massive irreparable rotator cuff tears where primary or partial repair was not possible. PATIENTS AND METHODS: We prospectively reviewed 22 patients who underwent an open interposition bridging repair with an allograft (GraftJacket) sutured medially to the residual rotator cuff stump and laterally to the footprint with suture anchors. Mean age at time of surgery was 59 years (range 53-66 years). The Oxford Shoulder Score, pain visual analogue scale and range of motion were compared pre-operatively and at mean follow up of 2.8 years. All patients had a postoperative MRI scan. RESULTS: There was a significant improvement in mean Oxford Shoulder Score from a pre-operative score of 14.2-34.3 points (p < 0.01) at final follow up. Pain VAS score improved from 6.6 points to 2.8 points (p < 0.05). Significant improvements in range of motion were also seen. Postoperative MRI scans showed a retear in 8 patients (36%), but the retear size was smaller and an improvement in outcomes maintained at final follow up. CONCLUSION: Open dermal allograft bridging repair for massive irreparable rotator cuff tears can lead to satisfactory outcomes and delay the need for a reverse shoulder arthroplasty.

The Management of Distal Clavicle Fractures - A Survey of UK Shoulder and Elbow Surgeons.

Background Distal clavicle fractures (DCF) are a management challenge frequently encountered by shoulder surgeons. Despite an array of surgical fixation strategies, the indications and role of surgery are unclear, with there being no gold standard or consensus regarding their management. The aim of this study was to identify current United Kingdom (UK) clinical practices relating to DCFs and to inform a future randomised control trial (RCT). Methods An online survey was sent to the consultant surgeon members of the British Elbow and Shoulder Society (BESS). Questions covered respondent indications for surgical fixation, important factors considered for management of DCFs, fixation strategies, the volume of patients treated, and willingness to participate in the conduct of a randomized trial. Results The response rate was 84/327 (26%). 64-67% of respondents reported surgically managing DCFs classified as Neer type 2A, 2B and 5. The most important factors considered by surgeons when deciding between operative and nonoperative intervention were degree of displacement (90%), clinical assessment of impending open fracture (87%), and age of the patient (74%). For conservatively managed DCFs, the preferred length of complete immobilization was 2-4 weeks (46%), followed by 4-8 weeks (17%). 30% reported not immobilizing their patients at all. For operative intervention, the locking plate was the preferred fixation method by most respondents (68%), although there was no clear consensus regarding other fixation methods. Most surgeons (52%) reported treating a low volume of patients with DCFs (0-10) per year. 58% of respondents were willing to randomize patients to non-operative treatment in a multi-centre RCT, with a further 22% undecided. Finally, 68% (n=79) of respondents would consider being co-investigators in such a trial. Conclusion There is considerable heterogeneity in the management of patients with DCFs in the UK. The indications for surgery and the optimal surgical fixation method remain uncertain. There is a clear need for pragmatic multi-centre clinical research in this area.

Common tendinopathies around the elbow; what does current evidence say?

Tendinopathies are common causes of pain around the elbow resulting in significant functional impairment in athletes or the working-age population. Patients complain of a gradual onset pain with or without any specific trauma. Tissue histology shows chronic fibroblast and vascular proliferation, with a disorganized collagen pattern and absence of inflammatory mediators. Currently, numerous treatment options are described, but many of these are only supported by a heterogenous evidence base. Thus, management guidelines are difficult to define. Surgery is mostly indicated in selected cases that have failed non-operative management. This article reviews the pathophysiology and natural history of lateral and medial elbow tendinopathies, as well as distal biceps and triceps tendinopathies, and their current treatment options.

Preoperative partial-thickness rotator cuff tears do not compromise anatomic total shoulder replacement outcomes: medium-term follow-up.

BACKGROUND: Reverse total shoulder replacement (TSR) in elderly patients with primary osteoarthritis (OA) and rotator cuff pathology is increasingly being performed. The purpose of our study was to determine the medium-term results of anatomic TSR for OA in patients with established preoperative partial-thickness rotator cuff tears on magnetic resonance imaging (MRI) scans. METHODS: We reviewed a cohort of patients who had undergone anatomic TSR for OA with a preoperative MRI diagnosis of partial-thickness rotator cuff tear. Patients were assessed with preoperative and post operative Oxford Shoulder Scores, evaluation of their range-of-movement and clinical rotator cuff assessment. Anteroposterior and axillary radiographs were used to assess for any proximal humeral migration (using the Torchia classification) and any evidence of loosening. The Lazarus score was used to grade glenoid radiolucencies. RESULTS: The study comprised 36 patients (14 men and 22 women) who underwent TSR and had partial-thickness rotator cuff tears on MRI; preoperatively, all showed mild to moderate fatty infiltration. The mean age of the patients was 79.2 years (range, 75-88 years); the mean follow-up period was 5.8 years (range, 5-9 years). Significant improvements in pain and range of movement were reported in all cases. At the final follow-up, the mean Oxford Shoulder Score was 42 points (range, 32-46 points), with a minimum improvement of 14 points (P = .001). External rotation (20° vs. 40°, P = .001), forward flexion (80° vs. 140°, P = .015), abduction (45° vs. 90°, P = .015), and internal rotation also improved. Lucencies were observed in 8 glenoids, with 6 showing grade 1 Lazarus changes, 2 showing grade 2, and none showing grade 3. There were no cases of implant loosening. Clinically, 4 patients had rotator cuff weakness but only 2 showed evidence of proximal migration. One patient remained satisfied, whereas the other patient, with moderate-grade proximal migration according to the Torchia classification, underwent revision for rotator cuff failure; one further patient underwent washout and DAIR (débridement, antibiotics, and implant retention) for infection. DISCUSSION: There is a paucity of literature on whether a preoperative partial-thickness rotator cuff tear has an adverse effect on the outcome of TSR. Our results show that the presence of a partial cuff tear on preoperative MRI does not significantly affect function after anatomic TSR in the medium term. With anatomic TSR having less morbidity for patients and allowing greater potential options for revision, we believe that the use of reverse shoulder arthroplasty in this cohort of patients, with partial rotator cuff tears, may not be necessary and we advocate consideration of anatomic TSR in this patient group.

A systematic review of management of scapular fractures.

There is no agreement within literature regarding management of scapula fractures. Our aim was to carry out a systematic review of literature on management of the scapular fractures. Our search across multiple medical databases for studies on the scapular fractures until February 2014 yielded 32 studies. We have excluded case series <7 patients, case reports, review articles, articles without abstract, observational studies and articles on fractures following shoulder arthroplasty. There were 8 prospective case series and one cohort study, however, majority of the included studies were retrospective studies. There were 1237 patients, follow up data were available for 941 patients who underwent either conservative (629) or operative management (512). Non-operative management scapular body fractures had satisfactory results. The scapular neck fractures displaced <10mm have satisfactory outcome following non-operative management. Operative management of displaced glenoid fossa fractures and scapular neck fractures displaced >10mm lead in a better functional outcome.

Current Concepts in the Management of Shoulder Instability.

Shoulder instability ranges from subtle instability to frank dislocation. Our understanding on the subject is getting better. Patient lifestyle, increased awareness/expectations, better availability of information, improved imaging modalities, and increased awareness about the previously less known concepts in instability all add to the challenges of managing the problem. History and clinical examination without over reliance on imaging remain essential. We used Embase, PubMed, Medline, CINAHL, Cochrane Library, Scottish Intercollegiate Guidelines Network and Google Scholar search for published literature in English. We used various combinations of the keywords, namely, human shoulder instability, sports injuries, dislocation, surgery, latarjet, glenohumeral, glenoid, and arthroscopy from 1980 to March 2017. The systematic search captured 310 publications. After applying initial exclusion criteria, 41 abstracts were assessed for eligibility. Of these, we selected 20 full-text articles with the majority of focus primarily on surgical management of traumatic shoulder instability. A tailor-made approach for the management of the individual patient is essential and should involve shared decision making. In this article, we have tried to simplify and present the current evidence in the management of traumatic shoulder instability, particularly in sportsperson.

Outcome of partial repair of massive rotator cuff tears with and without human tissue allograft bridging repair.

BACKGROUND: The surgical management of massive rotator cuff tears remains a challenge. It is suggested that, even in a massive tear that appears irreparable, attempting to repair it as much as possible can be helpful in improving functional outcomes. However the results can be short term and variable. The purpose of our study was to determine if human tissue allograft bridged repair of massive irreparable rotator cuff tears to achieve a complete repair produces similar outcomes compared to partial repair alone. METHODS: We prospectively reviewed outcome scores in 13 patients who underwent partial repair alone for massive irreparable rotator cuff tears and compared them to 13 patients who had partial repairs bridged with allograft. Oxford and Constant scores were compared pre-operatively and at a minimum follow-up of 2 years (range 2 years to 5 years). RESULTS: The mean improvement in the Constant score at final follow-up compared to pre-operative scores was 27.7 points in the partial repair group and 42.8 points in the allograft group (p < 0.01). The Oxford Shoulder Score improved mean of 19.3 points in the partial repair group and 29 points in the allograft group (p < 0.02) at 2 years. CONCLUSIONS: Human tissue matrix allograft provides a better outcome for open bridging of irreparable rotator cuff tears than partial repair alone.

A preoperative scoring system to select patients for arthroscopic subacromial decompression.

BACKGROUND: This study investigated the clinical and radiographic factors that influence outcome after arthroscopic subacromial decompression (ASAD) for shoulder impingement syndrome. The goal was to develop a new preoperative scoring system to identify patients who would have a prompt and sustained benefit from ASAD. METHODS: We prospectively reviewed 112 consecutive patients with impingement syndrome who subsequently underwent ASAD. The Oxford Shoulder Score (OSS) was recorded preoperatively and 3 and 12 months postoperatively. A statistically significant improvement in OSS at 3 months after surgery was considered a good outcome. RESULTS: The variables associated with good outcome were shoulder pain with overhead activities, persistent symptoms for more than 6 months, symptoms persistent despite a 3-month course of supervised physiotherapy, consistently positive Hawkins test result, radiologic changes of impingement on both acromion and humerus in the subacromial region, and improvement for more than 1 week after a steroid injection. These 6 criteria were combined into a single score for this study, termed the preoperative score (PrOS). Sixty-two patients who had been symptomatic for 1 year with a preoperative score of 5 to 6 showed significant improvement in OSS at 3 months after surgery (P < .001). Thirty-eight patients with a score 3 to 4 had no statistically significant improvement in OSS at 3 months but had a further slight improvement at 1 year. Twelve patients with a score of ≤2 had no significant improvement in OSS at 3 months or 1 year. CONCLUSION: This scoring system can identify patients who would have a prompt benefit from ASAD. The impact of surgery in patients with a PrOS of ≤4 points is questionable.

Factors influencing mortality in patients on antiplatelet agents presenting with proximal femoral fractures.

PURPOSE: To identify factors predicting one-year mortality in patients on clopidogrel presenting with proximal femoral fractures. METHODS: 9 men and 22 women aged 64 to 97 (mean, 81; standard deviation, 8) years who had been taking clopidogrel for ischaemic heart disease (n=15), cerebrovascular disease (n=6), or both (n=10) presented with proximal femoral fractures. The time from injury to operation, type of anaesthesia, treatment method, and postoperative complications were reviewed. One-year mortality was analysed using the Kaplan-Meier curve. Factors predicting one-year mortality were identified. RESULTS: The fracture configurations of the 31 patients included intracapsular femoral neck fracture (n=17), intertrochanteric fracture (n=13), and subtrochanteric fracture (n=1). 30 of the patients underwent hemiarthroplasty (n=16), dynamic hip screw fixation (n=9) or intramedullary hip screw fixation (n=5). The remaining patient underwent conservative treatment owing to metastatic prostate cancer. Of the 30 patients who underwent surgery, clopidogrel was discontinued at least 7 days prior to surgery, with the mean delay to surgery being 8.4 (range, 2-16) days. No patient had excessive blood loss at operation, although 7 patients received a blood transfusion postoperatively. 13 (43%) patients developed postoperative complications. The one-year mortality was 26% (8/31). Univariate analysis showed that factors predicting one-year mortality were spinal anaesthesia (p=0.04), postoperative blood transfusion (p=0.03), postoperative complications (p=0.03), and delay to surgery (p=0.03). Multiple regression analysis showed that delay to surgery (p=0.03) was the only independent predictor of one-year mortality, with a hazard ratio of 1.357 (95% confidence interval, 1.03-1.79). CONCLUSION: Surgery should be performed as soon as possible in medically fit patients having proximal femoral fractures who are taking clopidogrel, as delay to surgery is associated with increased one-year mortality.

Impact of organisational changes on fracture neck of femur management.

INTRODUCTION: In 2005, University Hospitals of Leicester formed a Fracture Neck of Femur (#NOF) project group to improve care of this group of patients. SUBJECTS AND METHODS: The salient changes effected by the group were the appointment of designated orthogeriatricians, trauma co-ordinators, clinical aides, and discharge nurses. RESULTS: As a result of these measures, the number of patients going to theatre within 48 h of admission rose from 38.5% in 2005/6 to 90% in 2007/8. In-hospital mortality decreased from 16.5% in 2005/6 to 10.9% in 2007/8. The 30-day mortality dropped from 13% in 2005/6 to 10.9% in 2007/8. Hospital stay reduced from 29 days in 2005/06 to 17 days in 2007/8. CONCLUSIONS: Re-organisation of available resources has a positive impact on reducing mortality and in-hospital stay of fracture neck of femur patients.

Cost-effectiveness of open versus arthroscopic rotator cuff repair.

BACKGROUND: Economic evaluation of surgical procedures is necessary in view of more expensive newer techniques emerging in an increasingly cost-conscious health care environment. This study compares the cost-effectiveness of open rotator cuff repair with arthroscopic repair for moderately size tears. MATERIALS AND METHODS: This was a prospective study of 30 consecutive patients, of whom 15 had an arthroscopic repair and 15 had an open procedure. Clinical effectiveness was assessed using Oxford and Constant shoulder scores. Costs were estimated from departmental and hospital financial data. RESULTS: At last follow-up, no difference Oxford and Constant shoulder scores was noted between the 2 methods of repair. There was no significant difference between the groups in the cost of time in the operating theater, inpatient time, amount of postoperative analgesia, number of postoperative outpatient visits, physiotherapy costs, and time off work. The incremental cost of each arthroscopic rotator cuff repair was pound675 ($1248.75) more than the open procedure. This was mainly in the area of direct health care costs, instrumentation in particular. DISCUSSION: Health care policy makers are increasingly demanding evidence of cost-effectiveness of a procedure. This study showed both methods of repair provide equivalent clinical results. CONCLUSION: Open cuff repair is more cost-effective than arthroscopic repair and is likely to have lower cost-utility ratio. In addition, the tariff for the arthroscopic procedure in some health care systems is same as open repair.
