The purpose of this study was to examine five-year outcomes of patients previously enrolled in a non-operative rotator cuff study.

Patients with chronic, full-thickness rotator cuff tears (demonstrated on imaging) who were referred to one of two senior shoulder surgeons were enrolled in the study between October 2008 and September 2010. Patients participated in a comprehensive non-operative, home-based treatment program. After three months patients were defined as “successful” or “failed”. “Successful” patients were essentially asymptomatic and did not require surgery. “Failed” patients were symptomatic and consented to surgical repair. All patients were followed up at one year, two years, and five-plus years.

Original results of our study showed that 75% of patients were treated successfully with non-operative treatment, while 25% went on to surgery. These numbers were maintained at two-year follow-up (previously reported) and five-year follow-up. At five+ years, 88 patients were contacted for follow-up. Fifty-eight (66%) responded. The non-operative success group had a mean RC-QOL score of 80 (SD 18) at previously reported two-year follow-up. At five-year follow-up this score did not decrease (RCQOL = 82 (SD 16)). Furthermore, between two and five years, only two patients who had previously been defined as “successful” became more symptomatic and underwent surgical rotator cuff repair. From the original cohort of patients, those who failed non-operative treatment and underwent surgical repair had a mean RC-QOL score of 89 (SD 12) at five-year follow-up. The operative and non-operative groups at five-year follow-up were not significantly different (p = 0.07).

Non-operative treatment is an effective and lasting option for many patients with a chronic, full-thickness rotator cuff tear. While some may argue that non-operative treatment delays inevitable surgical fixation, our study shows that patients can do extremely well over time.

Clinical pathways are optimal patient care processes that have been developed to improve the quality of care for patients. Anecdotal evidence has suggested that patients presenting to the healthcare system with rotator cuff tears experience less than ideal quality care plagued by lengthy wait times, challenges in coordinating care, and inefficient use of healthcare resources. Therefore, diagnosis and treatment of patients with rotator cuff tears are in need of quality improvement through evidence-informed decision making. The purpose of this study is to develop a clinical pathway for patients presenting to the healthcare system with rotator cuff tears.

The following steps were taken in developing the clinical pathway: 1) a multidisciplinary expert panel was formed; 2) goals of the clinical pathway were identified by the panel; 3) the literature and current clinical practices for best practice were reviewed; 4) recommendations for treatment algorithms were developed using consensus methods.

The panel consisted of fourteen experts representing the two largest cities in Alberta, Canada (Edmonton and Calgary). The team consisted of at least one member from the clinical domains of sport medicine, orthopaedic surgery, athletic therapy, and physiotherapy. The first goal of the clinical pathway was to standardise screening, diagnosis, and physical examination of the patient. The second goal was to provide recommendations for appropriate investigations. The final goal was to map steps in the patients' care pathway including sequencing and timing recommendations for treatment and interventions. Best practices were reviewed by the panel and using a modified Delphi method, clinical pathways for three types of rotator cuff tears (acute, chronic, and acute-on-chronic) were developed.

A clinical pathway that reflected best practices was developed from the literature and experts. The clinical pathway for diagnosis and treatment of patients with rotator cuff pathology will help to standardised patient care, improve patient flow, reduce unnecessary interventions, reduce healthcare utilisation and costs, and improve the quality of patient care.

Purpose

Electrothermal arthroscopic capsulorrhaphy (ETAC) was a technology introduced for orthopaedic surgery without good scientific clinical evidence supporting its use. This multicentre randomized clinical trial provides the scientific clinical evidence comparing ETAC to Open Inferior Capsular Shift (ICS), by measuring disease-specific quality of life at 2-years post-operatively, in patients with shoulder instability due to capsular redundancy.

ACL deficiency can have detrimental pathological effects on the menisci in the knee. A database review in Quebec over a three-year period was previously reported (Canadian Academy of Sport Medicine, Winnipeg, 2003), which examined the relationship between waiting times for ACL surgery and the requirement of a meniscal procedure. The purpose of this study is to determine if the length of time between an index injury and ACL reconstruction (ACLR) surgery correlates with the incidence of meniscal repair and meniscectomy in Alberta, and to compare the results to those of the Quebec study.

Retrospective study, using procedure and billing codes to search the Alberta Health and Wellness databases for knees undergoing primary ACLR surgery between 2002–2005. Inclusion: Patients sixteen years or older at time of reconstruction. Exclusion: Revision ACLR, duplicate billing and coding, and insufficient database information. For each reconstructed knee, databases were searched for initial injury evaluation date with primary care physician, dates of meniscectomy or meniscal repair procedures, and date of ACLR.

Over a three-year period, there were 3382 primary ACL reconstructions performed in Alberta, 3812 ACLR in Quebec. Of these patients, 2583 in Alberta (76%) and 1722 in Quebec (45%) required a meniscal procedure. On average, Albertans waited 1389 days from injury to ACLR compared to 422 days in Quebec. In Alberta, patients not requiring a meniscal procedure waited 1212 days, patients requiring meniscal repair waited 1143 days, and patients requiring meniscectomy waited 1519 days, compared to 251, 413 and 676 days in Quebec, respectively. Three percent of patients in Alberta had ACLR < three months after injury (114 patients), with 45% requiring meniscectomy. Overall, 61% of patients in Alberta required a meniscectomy for significant meniscal injury, compared to 48% of patients in Quebec. The proportions for each province were statistically significant.

Compared to Quebec, patients in Alberta are waiting longer for ACLR, with only a small proportion of cases being treated acutely. The proportion of patients requiring surgery for significant meniscal injury is also greater in Alberta. The higher proportion of patients in Alberta requiring meniscectomy may be due to the delay in ACLR.

The current standard of care in Calgary, Alberta for management of a ruptured Achilles tendon is surgical repair, typically performed following admission to hospital. The primary objective of this study was to compare the costs of hospital treatment and complications associated with the surgical repair of Achilles tendon ruptures between two groups of patients: Group One = patients enrolled in the randomised clinical trial (RCT) Multicentre Achilles Tendon Treatment Study (MATTS), Group Two = all other non-study patients.

This observational cohort study analyzed all patients surgically treated for Achilles tendon ruptures at Calgary area hospitals over a three-year period (October 2002–September 2005). Inclusion criteria: age eighteen to seventy years, acute rupture.

A total of two hundred and eighty-two patients met the inclusion criteria; thirty-three patients were included in Group One, two hundred and forty-nine patients in Group Two. In Group One, twenty-seven patients (82%) were treated as outpatients, five patients (15%) were ADOP-24hr, and one patient (3%) was admitted. In Group Two, twenty-seven patients (11%) were treated as outpatients, ninety-five patients (38%) were ADOP-24hr, and one hundred and twenty-seven patients (51%) were admitted. The total costs for patients treated as outpatients and requiring overnight stays in Group One were $18,408 and $7,419, respectively. In Group Two, the total cost for outpatients was $18,071 compared to $379,496 for non-study patients requiring overnight stay. If all overnight patients in each group were treated as outpatients, the total savings would be $235,545. There were no serious complications in Group One. In Group Two, complications included two cases of pulmonary embolus, and one case of compartment syndrome requiring readmission. All complications resolved.

Surgical treatment of Achilles tendon rupture can be performed safely and at less cost on an outpatient basis. Participation in this RCT has allowed us to recommend a change in the standard of care in Calgary.

This meta-analysis supports the conclusion that in patients with recurrent traumatic anterior shoulder instability, an open repair has a more favorable outcome with respect to recurrence and return to activity when compared to arthroscopic repair. More evidence from randomized clinical trials is required to either refute or substantiate this conclusion.

The purpose of this study was to evaluate the outcomes between arthroscopic and open repair for recurrent traumatic anterior shoulder instability.

The search involved clinical studies of all languages in the Medline database up to October 31, 2001. The following key words were used:

anterior shoulder instability;

All abstracts were reviewed and articles were included if there was a direct comparison between arthroscopic and open repair for traumatic recurrent anterior shoulder instability. These articles were manually assessed and cross-referenced for additional abstracts. The final group of articles were independently critically appraised and data on recurrent instability and return to activity (RTA) was extracted.

Recurrent instability was defined as patient report of one or more subluxations and/or dislocations. RTA was not consistently defined in these articles and was based upon the available information.

584,

From these searches, sixteen articles were determined eligible for the meta-analysis including two foreign and two unpublished manuscripts. Ten studies were included in the final analysis: one RCT, two pseudo-experimental designs, four prospective cohorts, and three retrospective studies.

Pooled Mantel-Haenszel Odds Ratio for recurrent instability and RTA were 2.22 (p=0.002, 95%CI 1.36,3.65) and 2.85 (p=0.004, 95%CI 1.40,5.78) respectively, in favor of the open repair.

Based upon this meta-analysis open repair has a more favorable outcome with respect to recurrence and RTA.

The standard of reference by which many imaging studies and clinical tests are often measured is arthroscopy. However, the inter-rater reliability of a surgeon’s arthroscopic diagnosis a relatively unexplored area of investigation. The purpose of the study was to determine the inter-rater reliability among a group of experienced orthopaedic shoulder surgeons in evaluating the intra-articular structures involved in a real-time diagnostic shoulder arthroscopy using a videotape model. Given the conditions of this study, the agreement among experienced shoulder surgeons was structure dependent ranging from poor to very good and was influenced by the prevalence of pathology.

To determine the inter-rater reliability among a group of experienced orthopaedic shoulder surgeons in evaluating the intra-articular structures involved in a real-time diagnostic shoulder arthroscopy using a videotape model.

In this patient population, the agreement among experienced shoulder surgeons was structure dependent ranging from poor to very good and was influenced by the prevalence of pathology.

For educational, research and legal reasons, it is important to objectively demonstrate that intra-operative findings can be reproduced. To date, this is a relatively unexplored area of investigation within shoulder arthroscopy.

The video-review surgeon median overall agreements were as follows: anterior labrum=90%, inferior labrum=45%, superior labrum=60%, posterior labrum=65%, superior glenohumeral ligament(GHL)=50%, middleGHL=50%, anterior-inferiorGHL=25%, glenoid surface=35%, detection of Hill Sachs lesion=85%, biceps tendon=70%, supraspinatus tendon=85%, infraspinatus tendon=70%, subscapularis tendon=80%.

Twenty patients (nineteen males, one female) diagnosed with recurrent anterior shoulder instability with an average age of 27.9 years (15–44years) consented to participate. One experienced surgeon performed a standardized diagnostic shoulder arthroscopy following a modified Snyder 15-point protocol. All surgeries were videotaped. The operative protocol, clarity of videotape information and data collection forms were pre-tested to ensure accuracy. The patients’ clinical information, x-rays and videotaped arthroscopy were sent to six experienced shoulder surgeons. The surgeons reviewed the clinical information, assessed the intra-articular structures shown on the videotape and recorded their diagnoses on a standardized data collection form. The primary outcome was the median overall percent agreement for the video-review surgeons. This was calculated for each structure evaluated.

This randomized clinical trial utilizing the validated rotator cuff disease specific quality of life outcome measure (RC-QOL) and adequate power demonstrates no difference in outcome for full thickness rotator cuff tears comparing open to mini-open surgical techniques.

The purpose of the study was to compare standard open rotator cuff repair versus mini-open rotator cuff repair by measuring the disease specific quality of life in patients with rotator cuff injury.

This randomized clinical trial utilizing a validated disease specific outcome measure and adequate power demonstrates no difference in outcome for full thickness rotator cuff tears comparing open to mini-open surgical techniques.

The miniopen approach utilizing an arthroscoic acromioplasty provides no additional beneifit to the patient undergoing a rotator cuff repair.

The mean one year RC-QOL score for the open and mini-open groups were 85.3 (SD = 15.6) and 87.4 (SD = 12.0) out of a maximum of one hundred, respectively. This difference was not statistically significant (p = 0.572).

Seventy-two patients (forty-eight males/twenty-four females) with an average age of 56.4 years (thirty-three to eighty-two years) consented to participate in the study. Inclusion criteria involved: unremitting pain, failed conservative treatment of at least three months, weakness of rotator cuff, and positive diagnostic imaging indicating a full-thickness rotator cuff tear. Massive rotator cuff tears were excluded.

Prior to surgery, patients were randomized to either open or mini-open rotator cuff repair. Patients were assessed and outcomes were collected at three, six and twelve months after surgery. Primary Outcome Measure: Patient quality of life was quantified using the validated disease specific, reliable and responsive Rotator Cuff Quality of Life Questionnaire (RC-QOL) measured on a one hundred point visual analogue scale format. Secondary Outcomes: Range of motion, strength, American Shoulder and Elbow Surgeons Score, and the Shoulder Rating Questionnaire.

The original RCT demonstrated that a limitedly-supervised post-ACL reconstruction rehabilitation program was both clinically more effective and less costly than the traditional physiotherapy-supervised program. This study contacted patients from the original RCT a minimum of two years post-surgery to evaluate whether or not the clinical findings of the RCT were upheld over the long term. This study of eighty-eight patients has upheld the original findings in that the patients who performed the limitedly-supervised (home-based) program had a significantly higher mean disease-specific quality of life score compared to the patients who performed the physiotherapy-supervised rehabilitation program.

To determine whether or not there were any differences in long-term outcome between those patients who performed a physiotherapy-supervised rehabilitation program (PT) and those who performed a primarily home-based rehabilitation program (H) in the first three months following ACL reconstruction.

Patients were originally randomized, before ACL reconstruction surgery, to either the physiotherapy-supervised (seventeen physiotherapy sessions) or home-based program (four physiotherapy sessions). Eighty-eight of the original patients were able to return two to four years following surgery to assess their long-term clinical outcomes. Primary outcome: the Mohtadi ACL disease-specific quality of life questionnaire (ACL QOL). Secondary outcomes: bilateral difference in knee extension and flexion range of motion, sagittal plane knee laxity, relative quadriceps and hamstrings strength, and IKDC score. Unpaired t-tests were used to compare the two groups across the continuous variables. A Chi square test was used for the categorical data.

The home-based group had a significantly higher (p = 0.02, 95% CI [18.4, 1.7]) mean ACL QOL score (80.0 ± 16.2) compared to the physiotherapy-supervised group (69.9 ± 22.0) a mean of forty months post-surgery. There were no significant differences between the two groups with respect to any of the secondary outcome measures.

This long-term study upholds the short-term findings of the original RCT in that the home-based rehabilitation program is more effective than a more physiotherapy-intensive program for patients in the first three months following ACL reconstruction.

Given the resource savings demonstrated in the original RCT, the home-based program is clearly economically-dominant (i.e., clinically more effective and less expensive).

This investigation was performed to determine whether MRI would provide any additional diagnostic information to the clinical evaluation and diagnostic arthroscopy of the shoulder. The study was performed in patients with shoulder impingement syndrome booked for an arthroscopic subacromial decompression. Although there was significant discordance between the MRI and arthroscopic findings, the MRI did not change the diagnosis or treatment plan in a clinically important way.

To determine whether the radiologist’s MRI report provided to an arthroscopist upon completion of a standard diagnostic shoulder arthroscopy would result in changes to the initial arthroscopic findings.

Despite high percentage of discordance between MRI and arthroscopy, the MRI information modified the initial arthroscopic diagnosis in a much smaller percentage of cases. In only one patient, did the change in diagnostic information have an impact on the planned treatment.

MRI adds minimal clinically important information to diagnostic shoulder athroscopy in patients with impingement syndrome.

The percentage discordance between MRI and arthroscopy for each structure of interest was calculated along with the percentage change in diagnosis based upon the arthroscopic re-evaluation and the consequence of the change.

Supraspinatus 55.2% discordance(n=32/58), 18.8% change in diagnosis(n=6/32), in 1 patient a change in the planned operation occurred from subacromial decompression to mini-open rotator cuff repair. Infra-spinatus 44.8% discordance(n=26/58), 3.8% change in diagnosis(n=1/26), and no consequence to planned treatment. Subscapularis 37.9% discordance(n=22/58), no change in diagnosis. Biceps tendon 62.3% discordance(n=33/53; five patients not adequately visualized on MRI), no change in diagnosis.

Fifty-eight patients presenting with shoulder impingement syndrome underwent a standardized MRI prior to planned arthroscopic subacromial decompression. A standard diagnostic arthroscopy was performed. The anatomic and pathologic findings were documented intra-operatively by an independent observer. The arthroscopist was initially blinded to the MRI information. MRI results were then revealed to the surgeon. An arthroscopic re-evaluation was performed to resolve discrepancies between MRI and arthroscopy.

Introduction and Aims: The authors have previously reported the comparison between MRI and arthroscopic diagnosis in a blinded prospective study in patients with shoulder impingement syndrome. The purpose of this investigation was to determine whether the radiologist’s MRI report provided to an arthroscopist upon completion of a standard diagnostic shoulder arthroscopy would result in changes to the initial arthroscopic findings.

Method: Fifty-eight patients presenting with clinical signs and symptoms of shoulder impingement syndrome underwent an MRI one week prior to planned arthroscopic subacromial decompression. MRI scans were obtained following a standardised protocol. Images were read by one musculoskeletal radiologist. A standard diagnostic arthroscopy was performed. The anatomic and pathologic findings were documented intra-operatively by an independent observer. The arthroscopist was initially blinded to the MRI information until completion of the standard diagnostic arthroscopy. MRI results were then revealed to the surgeon. An arthroscopic re-evaluation was performed to resolve any discrepancies between MRI and the initial arthroscopic findings.

Results: The percentage discordance between MRI and initial arthroscopic findings for each structure of interest was calculated along with the percentage change in diagnosis based upon the arthroscopic re-evaluation and the consequence of the change.

Supraspinatus 55.2% discordance (n=32/58), 18.8% change in diagnosis (n=6/32), in one patient a change in the planned operation occurred from subacromial decompression to mini-open rotator cuff repair. Infra-spinatus 44.8% discordance (n=26/58), 3.8% change in diagnosis (n=1/26), and no consequence to planned treatment. Subscapularis 37.9% discordance (n=22/58), no change in diagnosis. Biceps tendon 62.3% discordance (n=33/53; five patients not adequately visualised on MRI), no change in diagnosis. Acromion type 50% discordance (n=26/52; five patients did not have a sub-acromial bursocopy and in one patient the acromion was not well visualised), 7.7% change in diagnosis (n=2/26) with no consequence to planned treatment. Acromioclavicular joint 22.5% discordance (n=9/40; in 18 patients the AC joint was not entered), 11.1% change in diagnosis (n=1/9) with no consequence to planned treatment.

Conclusion: Despite high percentage of discordance between MRI and arthroscopy, the MRI information modified the initial arthroscopic diagnosis in a much smaller percentage of cases. In only one patient, did the change in diagnostic information have an impact on the planned treatment.

Pectoralis major tendon rupture is a relatively rare injury, resulting from violent, eccentric contraction of the muscle. Over fifty percent of these injuries occur in athletes classically in weight-lifters during bench press. In this study, thirteen cases of distal rupture of the pectoralis major muscle in athletes are presented. All patients underwent surgical repair.

Physical findings and surgical technique are described. Magnetic resonance imaging was used in the diagnosis of all patients and intra-operative findings correlated with the reported scans in eleven patients with minor differences in two patients. During follow up examination, six patients had excellent results, six had good results and one had a fair result. Eleven patients could return to sports activity at their preoperative level.

Among our patients we emphasize that of an orthopaedic resident who suffered a rupture of his pectoralis major tendon as an unusual complication of closed manipulation of an anterior shoulder dislocation.

According to the literature and our experience, we suggest that only surgical repair of the pectoralis major rupture will result in complete recovery and restoration of the full strength of the muscle which is essential for the active athlete.

The management of symptomatic single bundle Anterior Cruciate Ligament (ACL) ruptures is still a surgical dilemma. Preservation of the intact fibres of the ACL bundle is considered to be a possible source of reinnervation of the ACL autograft which reflects on better proprioceptive knee control after major ligament reconstruction. Results of a prospective study of 67 patients who had a double stranded but single bundle Anterior Cruciate Ligament (ACL) reconstruction for partial ACL ruptures are presented. There were 43 males and 24 females in this study with a mean age at the time of injury of twenty-five years (14 – 40). Eight played sport professionally and thirty-four played at a competitive level. A valgus twisting force was the most common mechanism of injury. Mean injury to operation time was 7.5 weeks (2–12). All procedures were done arthroscopically without using tourniquet, but using an arthroscopy pump and irrigation fluid containing adrenaline. The semitendinosis hamstring graft was used in all reconstructions. The mean follow-up period was 3.3 years (2–5.4). There was one major complication, who developed a reflex sympathetic dystrophy following a saphenous nerve neuroma. The Quality of Life (QOL) score was assessed using the Mohtadi index. The mean pre-operative QOL score of 30 (13–50) was improved to 93 (70–100) post-operatively. Fifty patients were able to return to their previous sporting level at a mean duration of 9 months (6–12).

Preservation of mechanoreceptors by performing a double stranded, single bundle ACL reconstruction in partial ACL ruptures in high demand patients yields good results and enables early return to high demand sports.
