RESUMO

BACKGROUND: In-season return to play after anterior glenohumeral instability is associated with high rates of recurrent instability and the need for surgical stabilization. We are not aware of previous studies that have investigated in-season return to play after posterior glenohumeral instability; furthermore, as posterior shoulder instability in collision athletes occurs frequently, understanding the expected outcome of in-season athletes may improve the ability of physicians to provide athletes with a better understanding of the expected outcome of their injury and their ability to return to sport. QUESTIONS/PURPOSES: (1) What proportion of athletes returned to play during the season after posterior instability in collegiate football players? (2) How much time did athletes lose to injury, what proportion of athletes opted to undergo surgery, and what proportion of athletes experienced recurrent instability after a posterior instability episode during a collegiate football season? METHODS: A multicenter, prospective, observational study of National Collegiate Athletic Association (NCAA) Division 1 Football Bowl Subdivision athletes was performed at three US Military Service Academies. Ten athletes who sustained a posterior instability event during the regular football season and who pursued a course of nonoperative treatment were identified and prospectively observed through the subsequent season. All athletes in the observed cohort attempted an initial course of nonoperative treatment during the season. All athletes sustained subluxation events initially identified through history and physical examination at the time of injury. None of the athletes sustained a dislocation event requiring a manual reduction. Intraarticular pathology consisting of posterior labral pathology was further subsequently identified in all subjects via MRI arthrogram. Return to play was the primary outcome of interest. Time lost to injury, surgical intervention, and subsequent instability were secondary outcomes. RESULTS: Of the 10 athletes who opted for a trial of initial nonoperative management, seven athletes were able to return to play during the same season. Although these seven athletes returned within 1 week of their injury (median of 1 day), 5 of 7 athletes sustained recurrent subluxation events with a median (range) of four subluxation events per athlete (0 to 8) during the remainder of the season. Seven athletes were treated surgically after the completion of their season, four of whom returned to football. CONCLUSION: This study suggests that although collegiate football players are able to return to in-season sport after a posterior glenohumeral instability event, they will likely sustain multiple recurrent instability events and undergo surgery after the season is completed. The results of this study can help guide in-season management of posterior shoulder instability by allowing more appropriate postinjury counseling and decision making through the identification of those athletes who may require additional attention from medical staff during the season and possible modifications to training regimens to minimize long-term disability. Further prospective studies involving a larger cohort over several seasons should be performed through collaborative studies across the NCAA that better assess function and injury risk factors before beginning collegiate athletics. This would better characterize the natural history and associated functional limitations that athletes may encounter during their collegiate careers. LEVEL OF EVIDENCE: Level IV, prognostic study.

RESUMO

PURPOSE OF REVIEW: This article examines the current literature reporting updates on trabeculectomy techniques, complications, and cost-effectiveness. RECENT FINDINGS: Trabeculectomy continues to be the standard for glaucoma surgery when a low intraocular pressure is required. Recent publications describe technique modifications that successfully increase efficacy and lower complications. There is also an ongoing effort to define the role of trabeculectomy in the management of glaucoma from a cost and public health standpoint. SUMMARY: The current literature continues to support the use of trabeculectomy as a method of lowering intraocular pressure in glaucoma management. Efficacy has been improved by ongoing surgical innovation, and reported complication rates are lower than those previously noted. Trabeculectomy has a favorable cost-benefit profile when compared with medical therapy or other surgical techniques. In spite of these ongoing changes, trabeculectomy appears to be decreasing in frequency in favor of newer surgeries and medications.

RESUMO

PURPOSE OF REVIEW: To examine the current literature covering the long-term effect of cataract extraction on intraocular pressure (IOP). RECENT FINDINGS: As a result of the high rate of cataract surgery, the impact on IOP continues to be the subject of multiple studies in different populations. Recent publications include those that distinguish patients with open angles from those with more narrow angles, as well as prospective analyses that address the impact of regression to the mean and other types of bias on the effect of postoperative IOP lowering. SUMMARY: There are sufficient data to suggest that cataract surgery provides a lowering effect on IOP in the long term. This effect appears to be proportional to preoperative IOP. Eyes with higher preoperative IOP have the greatest average lowering, whereas eyes with IOP in the lower range of statistically normal tend to have an IOP that is unchanged from baseline or even higher following cataract surgery. In patients with narrow angles, the IOP-lowering effect appears to also be proportional to the degree of anterior chamber deepening induced by cataract surgery.

RESUMO

BACKGROUND: One barrier to patient adherence with chronic topical glaucoma treatment is an inadequate amount of medication available between prescription refills. We examined the self-reported prevalence of early exhaustion of glaucoma eye drops prior to a scheduled refill, and associated risk factors. METHODS: This cross-sectional survey was performed at a University-based clinical practice. Glaucoma patients at the University of Washington who were experienced with eye drop application and were on a steady regimen of self-administered glaucoma drops in both eyes took a survey at the time of clinic examination. The main outcome measure was self-reported early eye drop bottle exhaustion. RESULTS: 236 patients were eligible and chose to participate. In general, patients included were relatively healthy (mean 2.3 comorbid medical conditions). Sixty patients (25.4%) reported any problem with early exhaustion of eye drop bottles, and this was associated with visual acuity ≤ 20/70 in the better eye (P = .049). Twelve patients (5.1%) reported that they "often" (5-7 times per year), "usually" (8-11 times per year) or "always" ran out of eye drops prior to a scheduled refill. Patients affected by this higher level (≥ 5 times yearly) of eye drop bottle exhaustion were more likely to have poor visual acuity in their worse eye ≤ 20/70 (P = .015) and had significantly lower worse-eye logMAR (P = .043). CONCLUSIONS: Self-reported early glaucoma bottle exhaustion regularly affected 5% of patients in our population and 25% reported early exhaustion at least once; the main risk factor was poor vision in at least one eye. These results may not be generalizable to a broad patient population, or to those inexperienced with eye drop self-administration. However, this pilot study compels further evaluation and consideration of early eye drop bottle exhaustion in glaucoma patients.

RESUMO

BACKGROUND: The objective of this study was to evaluate the effects of continuous subacromial bupivacaine infusion on supraspinatus muscle and rotator cuff tendon healing using gross, biomechanical, and histologic analyses. MATERIALS AND METHODS: Thirty-three New Zealand White rabbits underwent unilateral supraspinatus transection and rotator cuff repair (RCR). Rabbits were assigned to 1 of 3 groups: (1) RCR only, (2) RCR with continuous saline infusion for 48 hours, or (3) RCR with continuous 0.25% bupivacaine with epinephrine (1:200,000) infusion for 48 hours. Rabbits were euthanized postoperatively at 2 weeks (for histologic assessment) or 8 weeks (for biomechanical and histologic assessment). RESULTS: Tensile testing showed a significantly higher load to failure in intact tendons compared with repaired tendons (P < .01); however, no statistical differences were detected among RCR only, RCR saline, and RCR bupivacaine groups. Histologically, the enthesis of repaired tendons showed increased cellularity and disorganized collagen fibers compared with intact tendons, with no differences between treatment groups. Muscle histology demonstrated scattered degenerative muscle fibers at 2 weeks in RCR saline and RCR bupivacaine groups, but no degeneration was noted at 8 weeks. CONCLUSIONS: The healing supraspinatus tendons exposed to bupivacaine infusion showed similar histologic and biomechanical characteristics compared with untreated and saline-infused RCR groups. Muscle histology showed fiber damage at 2 weeks for the saline and bupivacaine-treated groups, with no apparent disruption at 8 weeks, suggesting a recovery process. Therefore, subacromial bupivacaine infusion in this rabbit rotator cuff model does not appear to impair muscle or tendon after acute injury and repair.

RESUMO

The purpose of this study was to determine the most common causes of failed anterior cruciate ligament reconstruction (ACLR) using modern reconstructive techniques at a single, high-volume institution. In addition, the clinical outcomes of patients undergoing revision ACLR will be reported. The surgical logs of four senior knee surgeons were retrospectively reviewed for all patients who had undergone ACLR between 2002 and 2009. Patients were excluded if they did not have both the primary and revision surgery on the same knee with the same surgeon. Out of 1944 ACL reconstructions, 28 patients (56 reconstructions) were included in the study. Radiographic studies, operative reports, KT-1000 scores, and chart notes were used to identify all potential factors that may have led to failure. All patients were invited to return for a follow-up examination and survey. Of the 28 patients, the mean age at the index and revision procedure was 22 +/- 11 (range, 12 to 50) and 24 +/- 11 (range, 14 to 57), respectively. In 20 cases, the cause of failure was determined to be acute trauma (sports, work, or accident); in 1 case, the cause was biologic failure; while in 7 cases, the cause was technical error. During the study period the surgeons performed a combined total of 1944 procedures, for an overall failure rate of 1.8%. Twenty patients (71%) were available for follow-up at a mean 30.2 +/- 17.7 months. The overall postrevision outcomes were good to excellent for a majority of patients, with an average Lysholm score of 84 +/- 15.5 and International Knee Documentation Committee score of 77.2 +/- 13.8. The pre- and postoperative KT-1000 scores were 12.1 +/- 2.8 and 6.7 +/- 2.8, respectively. The results from this study suggest that traumatic re-injury, and not surgical/surgeon error, is the most common cause of ACLR failure using anatomic reconstructive principles and strong fixation. In addition, good to excellent outcomes following revision ACLR can be expected in the majority of patients.

RESUMO

Traumatic injuries are a worldwide major cause of blindness and ocular morbidity. We report a series of four cases of fishing-related ocular trauma from the Pacific Northwest demonstrating the varied presentation and visual consequences of these injuries, including open and closed globe injuries, retained foreign bodies and retinal and subretinal hemorrhage. More efforts are needed to increase awareness and use of preventative measures.

RESUMO

INTRODUCTION: Musculoskeletal injuries are an endemic amongst U.S. Military Service Members and significantly strain the Department of Defense's Military Health System. The Military Health System aims to provide Service Members, military retirees, and their families the right care at the right time. The Military Orthopedics Tracking Injuries and Outcomes Network (MOTION) captures the data that can optimize musculoskeletal care within the Military Health System. This report provides MOTION structural framework and highlights how it can be used to optimize musculoskeletal care. MATERIALS AND METHODS: MOTION established an internet-based data capture system, the MOTION Musculoskeletal Data Portal. All adult Military Health System patients who undergo orthopedic surgery are eligible for entry into the database. All data are collected as routine standard of care, with patients and orthopedic surgeons inputting validated global and condition-specific patient reported outcomes and operative case data, respectively. Patients have the option to consent to allow their standard of care data to be utilized within an institutional review board approved observational research study. MOTION data can be merged with other existing data systems (e.g., electronic medical record) to develop a comprehensive dataset of relevant information. In pursuit of enhancing musculoskeletal injury patient outcomes MOTION aims to: (1) identify factors which predict favorable outcomes; (2) develop models which inform the surgeon and military commanders if patients are behind, on, or ahead of schedule for their targeted return-to-duty/activity; and (3) develop predictive models to better inform patients and surgeons of the likelihood of a positive outcome for various treatment options to enhance patient counseling and expectation management. RESULTS: This is a protocol article describing the intent and methodology for MOTION; thus, to date, there are no results to report. CONCLUSIONS: MOTION was established to capture the data that are necessary to improve military medical readiness and optimize medical resource utilization through the systematic evaluation of short- and long-term musculoskeletal injury patient outcomes. The systematic enhancement of musculoskeletal injury care through data analyses aligns with the National Defense Authorization Act (2017) and Defense Health Agency's Quadruple Aim, which emphasizes optimizing healthcare delivery and Service Member medical readiness. This transformative approach to musculoskeletal care can be applied across disciplines within the Military Health System.

RESUMO

PURPOSE: To evaluate the effect of screw length and diameter on the mechanical properties of biceps tenodesis (BT) with an interference screw in 2 different locations (proximal and distal). METHODS: We randomized 42 fresh-frozen human cadaveric shoulders (mean age, 65 ± 8 years) into 6 groups (n = 7): arthroscopic proximal BT using 7 × 15-, 7 × 25-, 8 × 15-, or 8 × 25-mm interference screws or distal subpectoral BT with 7 × 15- or 8 × 15-mm interference screws. Each repaired specimen was mounted onto a materials testing machine, preloaded to 5 N for 2 minutes, cycled from 5 to 70 N for 500 cycles (1 Hz), and loaded to failure (1 mm/s). Displacement during cyclical loading, pullout stiffness, and ultimate load to failure were computed, and the mechanism of failure was noted. RESULTS: All failures occurred at the tendon-screw interface. There was no statistically significant difference in ultimate displacement among all groups in the ultimate load to failure, displacement at peak load, and stiffness. CONCLUSIONS: There is no difference in ultimate load to failure, displacement at peak load, and stiffness of BT with regard to screw length or diameter at both proximal and distal tenodesis locations. These data would support use of a smaller-diameter and shorter implant for BT both proximally and distally. CLINICAL RELEVANCE: The results may serve as a guide to the orthopaedic surgeon performing proximal BT in selecting the appropriate interference screw. When possible, we recommend using the smallest screw size available to minimize risk of stress fracture at the tenodesis site.

RESUMO

BACKGROUND: COVID-19 is a severe respiratory virus that spreads via person-to-person contact through respiratory droplets. Since being declared a pandemic in early March 2020, the World Health Organization had yet to release guidelines regarding the return of college or professional sports for the 2020-2021 season. PURPOSE: To survey the head orthopedic surgeons and primary care team physicians for the National Collegiate Athletic Association (NCAA) Football Bowl Subdivision (FBS) football teams so as to gauge the management of common COVID-19 issues for the fall 2020 college football season. STUDY DESIGN: Cross-sectional study. METHODS: The head team orthopaedic surgeons and primary care physicians for all 130 FBS football teams were surveyed regarding their opinions on the management of college football during the COVID-19 pandemic. A total of 30 questions regarding testing, return-to-play protocol, isolating athletes, and other management issues were posed via email survey sent on June 5, 2020. RESULTS: Of the 210 team physicians surveyed, 103 (49%) completed the questionnaire. Overall, 36.9% of respondents felt that it was unsafe for college athletes to return to playing football during fall 2020. While the majority of football programs (96.1%) were testing athletes for COVID-19 as they returned to campus, only 78.6% of programs required athletes to undergo a mandatory quarantine period before resuming involvement in athletic department activities. Of the programs that were quarantining their players upon return to campus, 20% did so for 1 week, 20% for 2 weeks, and 32.9% quarantined their athletes until they had a negative COVID-19 test. CONCLUSION: While US Centers for Disease Control and Prevention guidelines evolve and geographic regions experience a range of COVID-19 infections, determining a universal strategy for return to socialization and participation in sports remains a challenge. The current study highlighted areas of consensus and strong agreement, but the results also demonstrated a need for clarity and consistency in operations, leadership, and guidance for medical professionals in multiple areas as they attempt to safely mitigate risk for college football players amid the COVID-19 pandemic.

RESUMO

BACKGROUND: The preferred patient-reported outcome measure for the assessment of shoulder conditions continues to evolve. Previous studies correlating the Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive tests (CATs) to the American Shoulder and Elbow Surgeons (ASES) score have focused on a singular domain (pain or physical function) but have not evaluated the combined domains of pain and physical function that compose the ASES score. Additionally, previous studies have not provided a multivariable prediction tool to convert PROMIS scores to more familiar legacy scores. PURPOSE: To establish a valid predictive model of ASES scores using a nonlinear combination of PROMIS domains for physical function and pain. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 3. METHODS: The Military Orthopaedics Tracking Injuries and Outcomes Network (MOTION) database is a prospectively collected repository of patient-reported outcomes and intraoperative variables. Patients in MOTION research who underwent shoulder surgery and completed the ASES, PROMIS Physical Function, and PROMIS Pain Interference at varying time points were included in the present analysis. Nonlinear multivariable predictive models were created to establish an ASES index score and then validated using "leave 1 out" techniques and minimal clinically important difference /substantial clinical benefit (MCID/SCB) analysis. RESULTS: A total of 909 patients completed the ASES, PROMIS Physical Function, and PROMIS Pain Interference at presurgery, 6 weeks, 6 months, and 1 year after surgery, providing 1502 complete observations. The PROMIS CAT predictive model was strongly validated to predict the ASES (Pearson coefficient = 0.76-0.78; R2 = 0.57-0.62; root mean square error = 13.3-14.1). The MCID/SCB for the ASES was 21.7, and the best ASES index MCID/SCB was 19.4, suggesting that the derived ASES index is effective and can reliably re-create ASES scores. CONCLUSION: The PROMIS CAT predictive models are able to approximate the ASES score within 13 to 14 points, which is 7 points more accurate than the ASES MCID/SCB derived from the sample. Our ASES index algorithm, which is freely available online (https://osf.io/ctmnd/), has a lower MCID/SCB than the ASES itself. This algorithm can be used to decrease patient survey burden by 11 questions and provide a reliable ASES analog to clinicians.

RESUMO

BACKGROUND: Patient-reported outcomes (PROs) measure progression and quality of care. While legacy PROs such as the International Knee Documentation Committee (IKDC) survey are well-validated, a lengthy PRO creates a time burden on patients, decreasing adherence. In recent years, PROs such as the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function and Pain Interference surveys were developed as computer adaptive tests, reducing time to completion. Previous studies have examined correlation between legacy PROs and PROMIS; however, no studies have developed effective prediction models utilizing PROMIS to create an IKDC index. While the IKDC is the standard knee PRO, computer adaptive PROs offer numerous practical advantages. PURPOSE: To develop a nonlinear predictive model utilizing PROMIS Physical Function and Pain Interference to estimate IKDC survey scores and examine algorithm sensitivity and validity. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: The MOTION (Military Orthopaedics Tracking Injuries and Outcomes Network) database is a prospectively collected repository of PROs and intraoperative variables. Patients undergoing knee surgery completed the IKDC and PROMIS surveys at varying time points. Nonlinear multivariable predictive models using Gaussian and beta distributions were created to establish an IKDC index score, which was then validated using leave-one-out techniques and minimal clinically important difference analysis. RESULTS: A total of 1011 patients completed the IKDC and PROMIS Physical Function and Pain Interference, providing 1618 complete observations. The algorithms for the Gaussian and beta distribution were validated to predict the IKDC (Pearson = 0.84-0.86; R2 = 0.71-0.74; root mean square error = 9.3-10.0). CONCLUSION: The publicly available predictive models can approximate the IKDC score. The results can be used to compare PROMIS Physical Function and Pain Interference against historical IKDC scores by creating an IKDC index score. Serial use of the IKDC index allows for a lower minimal clinically important difference than the conventional IKDC. PROMIS can be substituted to reduce patient burden, increase completion rates, and produce orthopaedic-specific survey analogs.

RESUMO

PURPOSE: The purpose of this study was to evaluate glenoid labral heights before injury and after repair with 2 suture anchors: (1) traditional suture anchor secured with knots and (2) knotless suture anchor. METHODS: Ten matched pairs of human cadaveric glenoids were examined. In each specimen the labrum was detached from the 3-o'clock position to the 6:30 clock position on the anteroinferior glenoid, and labral repair was performed with either (1) traditional Bio-SutureTak suture anchors (n = 10) (Arthrex, Naples, FL) or (2) knotless PushLock suture anchors (n = 10, contralateral side) (Arthrex). By use of a 3-dimensional digitizer, the labral height, measured from the deepest point of the glenoid articular surface to the highest tip of the labrum, was measured in all specimens before injury and after repair at the 3:30, 4:30, and 5:30 clock positions. The degree of labral height increase was computed as a percent increase in labral height from before injury to after repair. RESULTS: Labral height increased significantly for all specimens from before injury (5.35 mm) to after repair (8.05 mm) (159.1% +/- 13.7%, P < .0001). Increases in labral height from before injury to after repair were similar (P > .05) for Bio-SutureTak suture anchors (164.6% +/- 18.7%, P < .0001) and PushLock suture anchors (153.6% +/- 5.8%, P < .0001). The amount of labral height increase did not vary by anatomic location (157.0% +/- 50.2%, 168.9% +/- 51.0%, and 150.4% +/- 35.2% at 3:30, 4:30, and 5:30, respectively; P = .46). CONCLUSIONS: An increase in labral height can be achieved to create a significant height increase from before injury to after labral repair. The difference in labral height afforded by a traditional suture anchor and a knotless anchor is not statistically significant. CLINICAL RELEVANCE: Both traditional and knotless suture anchor constructs provide a reliable restoration of labral height in an acute Bankart model.

RESUMO

PURPOSE: The purpose of this systematic review was to critically evaluate the available literature in an attempt to compare the outcome of open versus arthroscopic distal clavicle resection in the treatment of acromioclavicular joint pathology. METHODS: From January 1966 to December 2008, Medline was searched for the following key words: "acromioclavicular joint arthritis," "acromioclavicular osteolysis," "distal clavicle excision," "acromioclavicular joint excision," "Mumford," and "clavicle." Inclusion criteria included studies that compared the outcome of open versus arthroscopic distal clavicle resection. Studies that could not be translated into the English language or were not published in a peer-reviewed journal were excluded. Data were abstracted from the studies, including patient demographics, surgical procedure, rehabilitation, strength, range of motion, and clinical scoring system. RESULTS: Seventeen studies met the inclusion criteria, including 2 Level II studies, 1 Level III and 14 Level IV studies. Arthroscopic distal clavicle excision results in more "good" or "excellent" outcomes compared with the open procedure. Both arthroscopic techniques result in success rates in excess of 90%, with the direct procedure permitting a quicker return to athletic activities. Performing distal clavicle excision in conjunction with either subacromial decompression or rotator cuff repair also has a high degree of success. A trend toward more "poor" results is seen when distal clavicle excision is performed in patients with post-traumatic acromioclavicular instability or in Workers' Compensation patients. CONCLUSIONS: Our analysis suggests that among patients undergoing distal clavicle excision for acromioclavicular joint pathology, those having an arthroscopic procedure, specifically through the direct approach, can expect a faster return to activities while obtaining similar long-term outcomes compared with the open procedure. LEVEL OF EVIDENCE: Level III, systematic review.

RESUMO

PURPOSE: Because recurrent or persistent defects in the rotator cuff after repair are common, we sought to clarify the correlation between structural integrity of the rotator cuff and clinical outcomes through a systematic review of relevant studies. METHODS: Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Central Register of Controlled Trials were searched for all literature published from January 1966 to December 2008 that used the key words shoulder, rotator cuff, rotator cuff tear, rotator cuff repair, arthroscopic, integrity, healed, magnetic resonance imaging (MRI), computed tomography arthrography (CTA), and ultrasound. The inclusion criteria were studies (Levels I to IV) that reported outcomes after arthroscopic rotator cuff repair in healed and nonhealed repairs based on ultrasound, CTA, and/or MRI. Exclusionary criteria were studies that included open repair or subscapularis repair and studies that did not define outcomes based on healed versus nonhealed but rather used another variable (i.e., repair technique). Data were abstracted from the studies including patient demographics, tear characteristics, surgical procedure, rehabilitation, strength, range of motion, clinical scoring systems, and imaging studies. RESULTS: Thirteen studies were included in the final analysis: 5 used ultrasound, 4 used MRI, 2 used CTA, and 2 used combined CTA/MRI for diagnosis of a recurrent tear. Statistical improvement in patients who had an intact cuff at follow-up was seen in Constant scores in 6 of 9 studies; in University of California, Los Angeles scores in 1 of 2 studies; in American Shoulder and Elbow Surgeons scores in 0 of 3 studies; and in Simple Shoulder Test scores in 0 of 2 studies. Increased range of motion in forward elevation was seen in 2 of 5 studies and increased strength in forward elevation in 5 of 8 studies. CONCLUSIONS: The results suggest that some important differences in clinical outcomes likely exist between patients with healed and nonhealed rotator cuff repairs. Further study is needed to conclusively define this difference and identify other important prognostic factors related to clinical outcomes. LEVEL OF EVIDENCE: Level IV, systematic review.

RESUMO

HYPOTHESIS: Patients with type II superior labrum, anterior to posterior (SLAP) lesions will have improved function and decreased pain at a minimum of 2 years after arthroscopic SLAP repair using bioabsorbable suture anchor fixation. MATERIALS AND METHODS: The study population consisted of 48 patients who underwent arthroscopic SLAP repair. Subjective shoulder scores, range of motion, and strength (postoperative only) were assessed preoperatively and at a minimum of 2 years postoperatively. RESULTS: At an average of 3.4 years after surgery, statistically significant improvement was seen in American Shoulder and Elbow Surgeons score, University of California, Los Angeles score, Simple Shoulder Test scores, Constant activities of daily living, visual analog scale for pain, and Short Form-12 Health Survey physical outcome scores. Improvements were made in forward flexion, abduction, external rotation, and internal rotation. Subgroup analysis of nonathletes, nonoverhead athletes, recreational overhead athletes, and collegiate overhead athletes showed preoperative to postoperative improvements in subjective outcomes scores. Overhead laborers and nonlaborers also showed preoperative to postoperative improvements in subjective shoulder scores. DISCUSSION: No differences were seen between the outcomes of nonathletes, nonoverhead athletes, recreational overhead athletes, and collegiate overhead athletes, suggesting that SLAP type II repair is successful independent of the patient's vocation or sport. CONCLUSION: These results show that arthroscopic SLAP repair of type II lesions with bioabsorbable suture anchors provides a significant improvement in functional capacity and pain relief.

RESUMO

BACKGROUND: Tenodesis of the long head of the biceps tendon is a common procedure used to alleviate pain caused by instability or inflammation of the tendon. The purpose of this study is to report on the incidence and types of complications following an open subpectoral biceps tenodesis (OBT) procedure. HYPOTHESIS: Our hypothesis was that the rate of adverse events after OBT was low. METHODS: From January 2005 to December 2007, all patients that underwent an OBT with bioabsorbable interference screw fixation performed by 1 of the 2 senior authors for biceps tendonitis were reviewed, excluding tenotomy, revision cases, or fixation methods other than interference screw fixation. RESULTS: Over a 3-year period, 7 of 353 patients had complications with OBT with an incidence of 2.0%. The mean age of patients with complications was 44.67 years, with 57.1% males and 42.9% females. There were 2 patients (0.57%) with persistent bicipital pain. Two patients (0.57%) had failure of fixation resulting in a Popeye deformity. One patient (0.28%) presented with a deep postoperative wound infections that necessitated irrigation and debridement with intravenous antibiotics. Another patient (0.28%) developed a musculotaneous neuropathy. Another patient (0.28%) developed reflex sympathetic dystrophy necessitating pain management and stellate ganglion block. CONCLUSION: The incidence of complications after subpectoral biceps tenodesis with interference screw fixation in a population of 353 patients over the course of 3 years was 2.0%.

RESUMO

PURPOSE: The purpose of this study was to compare the clinical outcome of single-row (SR) and double-row (DR) suture anchor fixation in arthroscopic rotator cuff repair with a systematic review of the published literature. METHODS: We searched all published literature from January 1966 to December 2008 using Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Central Register of Controlled Trials for the following key words: shoulder, rotator cuff, rotator cuff tear, rotator cuff repair, arthroscopic, arthroscopic-assisted, single row, double row, and transosseous equivalent. The inclusion criteria were cohort studies (Levels I to III) that compared SR and DR suture anchor configuration for the arthroscopic treatment of full-thickness rotator cuff tears. The exclusion criteria were studies that lacked a comparison group, and, therefore, case series were excluded from the analysis. RESULTS: There were 5 studies that met the criteria and were included in the final analysis: 5 in the SR group and 5 in the DR group. Data were abstracted from the studies for patient demographics, rotator cuff tear characteristics, surgical procedure, rehabilitation, range of motion, clinical scoring systems, and imaging studies. CONCLUSIONS: There are no clinical differences between the SR and DR suture anchor repair techniques for arthroscopic rotator cuff repairs. At present, the data in the published literature do not support the use of DR suture anchor fixation to improve clinical outcome, but there are some studies that report that DR suture anchor fixation may improve tendon healing. LEVEL OF EVIDENCE: Level III, systematic review of Levels I to III studies.
