Evaluating The Effect of Arthroscopic Rotator Cuff Repair with Concomitant Subacromial Decompression on 2, 4, and 6 Year Reoperation Rates.

The risks and benefits of including an arthroscopic subacromial decompression (ASD) during arthroscopic rotator cuff repair (RCR) are uncertain. Some studies suggest no difference in revision surgery rates, whereas others have found higher revision surgery rates associated with concomitant ASD. In this study, we compare mid-term revision surgery rates in patients undergoing arthroscopic RCR with or without concomitant ASD. A retrospective cohort analysis was conducted using a national all-payer claims database. Current Procedural Terminology and International Classification of Disease , 10th Revision , codes were used to identify patients who underwent primary arthroscopic RCR with or without ASD in the United States. The primary study outcome was revision surgery at 2, 4, and 6 years. Univariate analysis was conducted on demographic variables (age, sex) and comorbidities in the Elixhauser Comorbidity Index using chi-square and Student t -tests. Multivariate analysis was conducted using logistic regression. A total of 11,188 patients were identified who underwent RCR and met the inclusion criteria. Of those, 8,994 (80%) underwent concomitant ASD. Concomitant ASD was associated with lower odds of all-cause revision surgery to the ipsilateral shoulder at 2 years (odds ratio [OR], 0.61; 95% confidence interval [CI], 0.51 to 0.73), 4 years (OR, 0.60; 95% CI, 0.51 to 0.70), and 6 years (OR, 0.59; 95% CI, 0.51 to 0.69). Concomitant ASD was also associated with lower odds of revision RCR at 2 years (OR, 0.68; 95% CI, 0.53 to 0.86), 4 years (OR, 0.63; 95% CI, 0.50 to 0.78), and 6 years (OR, 0.61; 95% CI, 0.49 to 0.76). Arthroscopic RCR with concomitant ASD is associated with lower odds of all-cause revision surgery in the ipsilateral shoulder at 2, 4, and 6 years. The lower mid-term revision surgery rates suggest benefits to performing concomitant ASD with primary arthroscopic RCR. Continued research on the mid to long-term benefits of ASD is needed to determine which patient populations benefit most from this procedure. The data that support the findings of this study are available from the corresponding author upon reasonable request.

Glenohumeral Hydrodistension for Postoperative Stiffness After Arthroscopic Primary Rotator Cuff Repair.

Background:Postoperative stiffness is a known complication after rotator cuff repair (RCR). Glenohumeral hydrodistension (GH) has been a treatment modality for shoulder pathology but has not been used to treat postoperative stiffness after RCR.Purpose/Hypothesis:The purpose of this study was to identify the risk factors for postoperative stiffness after RCR and review outcomes after treatment with GH. Our hypotheses were that stiffness would be associated with diabetes and hyperlipidemia and correlated with the tendons involved and that patients with stiffness who underwent GH would have significant improvement in range of motion (ROM).Study Design:Case series; Level of evidence, 4.Methods:Included were 388 shoulders of patients who underwent primary RCR by a single surgeon between 2015 and 2019. Shoulders with revision RCRs were excluded. Patient characteristics, medical comorbidities, and perioperative details were collected. A total of 40 shoulders with postoperative stiffness (10.3%) received GH injectate of a 21-mL mixture (15 mL of sterile water, 5 mL of 0.5% ropivacaine, and 1 mL of triamcinolone [10 mg/mL]). The primary outcome measure was ROM in forward flexion, internal rotation, external rotation, and abduction. Statistical tests were performed using analysis of variance.Results:Patients with diabetes had significantly decreased internal rotation at final follow-up after RCR as compared with patients without diabetes. GH to treat stiffness was performed most commonly between 1 and 4 months after RCR (60%), and patients who received GH saw statistically significant improvements in forward flexion, external rotation, and abduction after the procedure. Patients with hyperlipidemia had the most benefit after GH. Among those undergoing concomitant procedures, significantly more patients who had open subpectoral biceps tenodesis underwent GH. Patients who underwent subscapularis repair or concomitant subacromial decompression had significant improvement in ROM after GH. Only 1 patient who received GH underwent secondary surgery for resistant postoperative stiffness.Conclusion:Patients with diabetes had increased stiffness. Patients with a history of hyperlipidemia or concomitant open subpectoral biceps tenodesis were more likely to undergo GH for postoperative stiffness. Patients who underwent subscapularis repair demonstrated the most improvement in ROM after GH. After primary RCR, GH can increase ROM and is a useful adjunct for patients with stiffness to limit secondary surgery.

Modified technique of Indirect arthroscopic distal clavicle resection

Distal clavicle resection is an accepted surgical treatment option for unremitting acromioclavicular joint arthritis. Indirect arthroscopic approach is preferred when an additional subacromial or glenohumeral diagnostic or therapeutic procedure is contemplated. However, concomitant subacromial decompression and acromial overhang removal, which is integral to indirect approach vis-a-vis direct approach, have additional risks of stiffness and acromial fracture. A modification in indirect approach technique is demonstrated which not only reduces these risks but also improves accuracy and safety of distal clavicle resection. The pros and cons are discussed in detail with reference to relevant literature.

Cost comparison of arthroscopic rotator cuff repair with arthroscopic vs. open biceps tenodesis

To use a nationwide database to determine differences in cost between patients who underwent arthroscopic rotator cuff tear with open vs. arthroscopic biceps tenodesis (BT). The 2014 State Ambulatory Surgical and Services Databases from 6 US states was utilized. All cases with CPT codes 29827 (arthroscopic rotator cuff repair [RCR]) and either 23430 (tenodesis of long tendon of biceps) or 29828 (arthroscopic BT) were selected. Cases that included both 23430 and 29828 were excluded, as were those missing demographic data. Generalized linear models were used to model costs based on the surgical and patient variables that were significant in the initial bivariate analysis (P < .05). A total of 3635 RCR and BTcases were identified. There were 2847 (78.3%) with arthroscopic BTand 788 (21.7%) with open BT. Patients undergoing arthroscopic BT were 3.1 years older than patients undergoing open BT (P < .001). For arthroscopic BT, 39.2% of the cases were women compared with 22.6% of the open cases (P < .001). For operative variables, arthroscopic BT required 9 fewer minutes in the OR than open cases (P = .002). Concomitant distal clavicle resection was performed in 35.5% of arthroscopic BT cases compared with 29.8% of open cases (P = .004). While controlling for other significant factors, open BT was associated with $5542 lower costs than arthroscopic BT in the setting of RCR (P < .001). In either case, concomitant subacromial decompression added $10,669 (P < .001), and distal clavicle resection added $3210 (P < .001). High-volume surgical facilities were associated with $4107 lower costs (P < .001). In a large series of patients undergoing arthroscopic RCR with open vs. arthroscopic BT, open BT was associated with $5542 lower costs than arthroscopic. Given that both techniques have been shown to be similarly effective in long-term follow-up, surgeons should be aware of opportunities for cost saving, particularly with the advent of bundled surgical reimbursements.

The primary cost drivers of arthroscopic rotator cuff repair surgery: a cost-minimization analysis of 40,618 cases

An estimated 250,000 rotator cuff repair (RCR) surgical procedures are performed every year in the United States. Although arthroscopic RCR has been shown to be a cost-effective operation, little is known about what specific factors affect the overall cost of surgery. This study examines the primary cost drivers of RCR surgery in the United States. Univariate analysis was performed to determine the patient- and surgeon-specific variables for a multiple linear regression model investigating the cost of RCR surgery. The 2014 State Ambulatory Surgery and Services Databases were used, yielding 40,618 cases with Current Procedural Terminology code 29827 ("arthroscopic shoulder rotator cuff repair"). The average cost of RCR surgery was $25,353. Patient-specific cost drivers that were significant under multiple linear regression included black race (P < .001), presence of at least 1 comorbidity (P < .001), income quartile (P < .001), male sex (P = .012), and Medicare insurance (P = .035). Surgical factors included operative time (P < .001), use of regional anesthesia (P < .001), quarter of the year (January to March, April to June, July to September, and October to December) (P < .001), concomitant subacromial decompression or distal clavicle excision (P < .001), and number of suture anchors used (P < .001). The largest cost driver was subacromial decompression, adding $4992 when performed alongside the RCR. There are several patient-specific variables that can affect the cost of RCR surgery. There are also surgeon-controllable factors that significantly increase cost, most notably subacromial decompression, distal clavicle excision, use of regional anesthesia, and number of suture anchors. Surgeons must consider these factors in an effort to minimize cost, particularly as bundled payments become more common.

Open Biceps Tenodesis Associated With Slightly Greater Rate of 30-Day Complications Than Arthroscopic: A Propensity-Matched Analysis

To compare the early complication risk associated with open biceps tenodesis (OBT) and arthroscopic biceps tenodesis (ABT) and determine which preoperative factors may influence complication rate. The American College of Surgeons National Surgical Quality Improvement Program database was retrospectively queried from 2008 to 2016 for all procedures with CPT codes for ABT (29828) and OBT (23430). Patients were excluded if they received concomitant rotator cuff repair or shoulder arthroplasty. Patients undergoing OBT and ABT were matched by propensity scores based on age, body mass index, operative time, proportion of smokers, and proportion of concomitant subacromial decompression, distal clavicle excision, SLAP, and debridement. The incidence of adverse events in the 30-day postoperative period was compared. A total of 8,032 patients met the inclusion and exclusion criteria. Prior to propensity match, patients receiving OBT and ABT, respectively, differed with respect to age (49.4 ± 13.8 vs 51.4 ± 13.2; P< .001), body mass index (29.6 ± 6.8 vs 29.9 ± 7.0; P= .029), and operative time (91.2 ± 51.3 vs 85.3 ± 43.4; P < .001). Following propensity match, 6,330 remained in the study (3,165 ABT and 3,165 OBT). OBT had significantly greater incidence of any adverse events (1.58% vs 0.95%; P= .032) and anemia requiring transfusion (0.35% vs 0%; P= .001). Multivariate analysis suggested that OBT (relative risk [RR]= 1.7, 95% confidence interval [CI], 1.1-2.7; P= .020), old age (RR= 1.6, 95% CI, 1.0-2.5), history of dyspnea (RR= 3.8, 95% CI, 1.8-7.7; P < .001), and congestive heart failure (RR= 5.5, 95% CI, 1.3-22.7; P= .019) were associated with developing a postoperative adverse event within 30days of surgery. Both procedures were found to have a low rate of complications, although OBT had a slightly greater (1.58% vs 0.95%) rate of 30-day complications than ABT. Early complication rate should not serve as impetus to direct surgical technique as number needed to treat is high, although ABT may be considered in more high-risk individuals. Level III, retrospective comparative database study.

Prevalence of Rotator Cuff Repairs with and Without Concomitant Subacromial Decompressions Has Not Changed.

Recent research from the American Board of Orthopaedic Surgery database indicates a decreasing rate of subacromial decompression (SAD) performed with rotator cuff repair (RCR) by younger orthopedic surgeons. The purpose of this study was to determine the rate of RCR with and without SAD and whether the rate of RCR with SAD decreased over time. Further, we set out to determine if there was significant variation in the rate of RCR with SAD by state. Rates of RCR with and without open or arthroscopic SAD from 2010 to 2012 were determined based upon de-identified data from a national health insurance carrier. Data were normalized per 10,000 insured patients for comparative analysis. Rates of RCR with concomitant SAD were higher than RCR without SAD in each year analyzed. In patients 50years old and older, this same significant difference was also seen for each year. The rate of RCR with or without SAD did not decrease over the 3-year time period. The rate of RCR performed concomitantly with SAD was significantly higher than RCR performed without SAD in all patient age groups combined. There was wide variation in the rate of RCR with or without concurrent SAD across states. Disproving our hypothesis, the overall rate of RCR with or without SAD did not decrease over the period from 2010 to 2012. There was wide variation in the rate of RCR by state; however, this variation was not seen in the incidence of SAD performed concomitant with the RCR.

Evaluation of the Trends, Concomitant Procedures, and Complications With Open and Arthroscopic Rotator Cuff Repairs in the Medicare Population.

Background:Medicare insures the largest population of patients at risk for rotator cuff tears in the United States.Purpose:To evaluate the trends in incidence, concomitant procedures, and complications with open and arthroscopic rotator cuff repairs in Medicare patients.Study Design:Cohort study; Level of evidence, 3.Methods:All Medicare patients who had undergone open or arthroscopic rotator cuff repair from 2005 through 2011 were identified with a claims database. Annual incidence, concomitant procedures, and postoperative complications were compared between these 2 groups.Results:In total, 372,109 rotator cuff repairs were analyzed. The incidence of open repairs decreased (from 6.0 to 4.3 per 10,000 patients, P < .001) while the incidence of arthroscopic repairs increased (from 4.5 to 7.8 per 10,000 patients, P < .001) during the study period. Patients in the arthroscopic group were more likely to have undergone concomitant subacromial decompression than those in the open group (87% vs 35%, P < .001), and the annual incidence of concomitant biceps tenodesis increased for both groups (from 3.8% to 11% for open and 2.2% to 16% for arthroscopic, P < .001). While postoperative complications were infrequent, patients in the open group were more likely to be diagnosed with infection within 6 months (0.86% vs 0.37%, P < .001) but no more likely to undergo operative debridement (0.43% vs 0.26%, P = .08). Additionally, patients in the open group were more likely to undergo intervention for shoulder stiffness within 1 year (1.4% vs 1.1%, P = .01).Conclusion:In the Medicare population, arthroscopic rotator cuff repairs have increased in incidence and now represent the majority of rotator cuff repair surgery. Among concomitant procedures, subacromial decompression was most commonly performed despite evidence suggesting a lack of efficacy. Infections and stiffness were rare complications that were slightly but significantly more frequent in open rotator cuff repairs.

Calcific tendonitis of the shoulder: is subacromial decompression in combination with removal of the calcific deposit beneficial?

We postulated that treatment of patients with calcific tendonitis of the supraspinatus tendon by debridement of the calcific deposit alone was comparable to treatment by debridement and concomitant subacromial decompression. During a 10-year period, 50 consecutive patients with calcific tendonitis refractory to nonoperative measures were surgically treated by debridement (D) as an isolated procedure (25patients) or by debridement and concomitant subacromial decompression (D+SAD; 25 patients), and the surgical groups were retrospectively compared. The main outcome of interest was the time to resumption of unrestricted activity without pain. An abbreviated version of disabilities of the Disabilities of Arm, Shoulder and Hand (QuickDASH) score and University of California-Los Angeles (UCLA) shoulder summary scores were compiled at a mean follow-up of 5 years (range, 2-10 years). Average time to return to activity without pain was significantly shorter for the D group compared with the D+SAD group (11 vs 18 weeks; P < .006). At the final evaluation, QuickDASH scores were equally low (group D, 6; group D + SAD, 11; P = .191), indicating that both treatment groupshadhigh levels of function. The mean UCLA shoulder scores at final evaluation were 33 for both groups (P = .678). Patients treated by debridement of the calcific deposit and concomitant subacromial decompression required a longer time to return to unrestricted activity without pain. Debridement of a calcific deposit alone is a better surgical option to treat calcific tendonitis.

Long-term results of arthroscopic resection of the distal clavicle with concomitant subacromial decompression

Purpose: The goal of the study was to evaluate the long-term outcome of combined arthroscopic distal clavicle excision and subacromial decompression. Type of Study: Retrospective, long-term cohort evaluation. Methods: Twenty patients with an average follow-up of 6 years (range, 3.9 to 9 years) were reviewed. All patients had ipsilateral impingement syndrome and acromioclavicular joint disease at the time of surgery and underwent arthroscopic subacromial decompression combined with arthroscopic distal clavicle excision. All patients returned for evaluation in person, in addition to filling out a questionnaire incorporating the University of California, Los Angeles (UCLA), and Constant scoring systems. Preoperative and postoperative radiographs were available for all patients. Results: Postoperatively, all patients had pain relief and were satisfied with the result. The average postoperative UCLA Shoulder score was 29.8 ± 0.6, compared with 17.5 ± 3.0 before surgery ( P = .001). The Constant Shoulder score averaged 98.5 ± 2.1 postoperatively, compared with 70.5 ± 11.2 preoperatively ( P = .001). There was 100% good to excellent results using both scoring systems. Individual components of the UCLA scoring system (pain, function, and power) all showed significant postoperative improvement ( P = .001). Constant categories of pain, activities of daily living, range of motion, and power also improved. Follow-up radiographs showed maintenance of the resected distal clavicle in 19 patients. Five patients (25%) had radiographic evidence of calcific density distal to the resected clavicle but were asymptomatic. Conclusions: The long-term results of arthroscopic resection of the distal clavicle with concomitant subacromial decompression are uniformly good or excellent. Impingement and acromioclavicular joint disease frequently coexist and should be identified and treated concurrently.

Arthroscopic resection of the distal aspect of the clavicle with concomitant subacromial decompression.

Arthroscopic subacromial decompression and arthroscopic resection of the acromioclavicular joint as separate procedures have been well documented. However, there is little information on the success rate of resection with concomitant decompression. In this study, we retrospectively evaluated the results of a consecutive group of patients who underwent arthroscopic resection of the acromioclavicular joint with concomitant subacromial decompression. We evaluated the surgical results in thirty-one consecutive patients (thirty-two shoulders) with acromioclavicular pathology with concomitant subacromial impingement. The mean age of the patients at the time of surgery was thirty-six years (range, eighteen to sixty-seven years). Twenty-five patients, including four professional athletes, were actively involved in sports activities. The mean duration of follow-up was four years and ten months (range, three to eight years). The follow-up examination included clinical evaluation, chart review, radiographic analysis, and isokinetic testing of both upper extremities. Of the twenty-five patients who participated in sports, twenty-two (including the four professional athletes) returned to their previous level of sports activity. Twenty-six patients had no pain, three reported mild pain on strenuous repetitive overhead activity, two (both weight-lifters) had occasional pain in the acromioclavicular joint and the lateral aspect of the shoulder with bench-pressing, and two (both baseball players) had mild pain in the posterior aspect of the shoulder with throwing. All of the patients were satisfied with the results. In the absence of a complete rotator cuff tear, isokinetic strength-testing of both upper extremities failed to demonstrate any weakness of the involved shoulder. The mean functional score for individual activities was 2.7 points (range, 2.1 to 3.0 points) preoperatively and 3.9 points (range, 3.6 to 4.0 points) postoperatively (p = 0.0001). No patient had superior migration of the clavicle. The amount of distal clavicular resection averaged 9 mm (range, 7 to 15 mm). One patient had heterotopic ossification at the resection site, with mild pain on direct palpation of the acromioclavicular joint and on strenuous overhead activity. Five patients had calcification at the anterior deltoid insertion into the acromion that was asymptomatic, with no impingement on overhead activity and no pain on direct palpation. We found excellent results with arthroscopic resection of the acromioclavicular joint and concomitant subacromial decompression. When this procedure is performed on properly selected patients, the results are similar to those of an open approach.

Arthroscopic fixation of superior labral lesions using a biodegradable implant: A preliminary report

Twenty-two patients were treated for symptomatic lesions of the superior glenoid labrum in association with instability of the tendinous insertion of the long head of the biceps brachii. A biodegradable implant was used to fix the labrum to the bony glenoid using an arthroscopic technique. At 2-year average follow-up, satisfactory results were obtained in 86% of the patients. Two patients, both of whom had undergone concomitant subacromial decompression, continued to complain of pain after the procedure; 3 patients had restricted motion postoperatively, and 1 required manipulation under anesthesia. Twelve of 13 overhead athletes were able to return to full premorbid function. Arthroscopic fixation of unstable lesions of the superior labrum led to a resolution of symptoms in the majority of patients. There were no complications related to the use of the biodegradable implant.
