BACKGROUND/UNASSIGNED:It is unclear whether leukocyte-poor (LP) or leukocyte-rich (LR) varieties of platelet-rich plasma (PRP) as an adjuvant to arthroscopic rotator cuff repair (ARCR) result in improved tendon healing rates. PURPOSE/UNASSIGNED:To perform a network meta-analysis of the randomized controlled trials in the literature to ascertain whether there is evidence to support the use of LP- or LR-PRP as an adjunct to ARCR. METHODS/UNASSIGNED:The literature search was based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Randomized controlled trials comparing LP- or LR-PRP with a control alongside ARCR were included. Clinical outcomes, including retears and functional outcomes, were compared using a frequentist approach to network meta-analysis, with statistical analysis performed using R. The treatment options were ranked using the P-score. RESULTS/UNASSIGNED:There were 13 studies (868 patients) included, with 9 studies comparing LP-PRP with a control and 4 studies comparing LR-PRP with a control. LP-PRP was found to significantly reduce the rate of retear and/or incomplete tendon healing after fixation, even among medium-large tears; it also improved outcomes on the visual analog scale for pain, Constant score, and University of California Los Angeles score. LP-PRP had the highest P-score for all treatment groups. LR-PRP did not result in any significant improvements over the control group, except for visual analog scale score for pain. However, post hoc analysis revealed that LP-PRP did not lead to significant improvements over LR-PRP in any category. CONCLUSION/UNASSIGNED:The current study demonstrates that LP-PRP reduces the rate of retear and/or incomplete tendon healing after ARCR and improves patient-reported outcomes as compared with a control. However, it is still unclear whether LP-PRP improves the tendon healing rate when compared with LR-PRP.

BACKGROUND/UNASSIGNED:Shoulder arthroscopy is one of the most commonly performed orthopaedic procedures used to treat a variety of conditions, with >500,000 procedures performed each year. PURPOSE/UNASSIGNED:To systematically review the randomized controlled trials (RCTs) on pain control after shoulder arthroscopy in the acute postoperative setting and to ascertain the best available evidence in managing pain after shoulder arthroscopy to optimize patient outcomes. STUDY DESIGN/UNASSIGNED:Systematic review and meta-analysis. METHODS/UNASSIGNED:A systematic review of the literature was performed based on the PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines. Studies were included if they were RCTs evaluating interventions to reduce postoperative pain after shoulder arthroscopy: nerve blocks, nerve block adjuncts, subacromial injections, patient-controlled analgesia, oral medications, or other modalities. Meta-analyses and network meta-analyses were performed where appropriate. RESULTS/UNASSIGNED:< .05). No benefit was found in any of the studies evaluating subacromial infusions. CONCLUSION/UNASSIGNED:Continuous interscalene block resulted in the lowest pain levels at most time points, although this was not significantly different when compared with the other nerve blocks. Additionally, nerve block adjuncts may prolong the postoperative block time and improve pain control. There is promising evidence for some oral medications and newer modalities to control pain and reduce opioid use. However, we found no evidence to support the use of subacromial infusions or patient-controlled analgesia.

BACKGROUND:The purpose of this study was to perform a systematic review and meta-analysis of the current evidence in the literature to determine how arthroscopic Bankart repair (ABR) and remplissage compare with ABR alone and the open Latarjet procedure for anterior shoulder instability in patients with concomitant Hill-Sachs lesions. METHODS:A literature search was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Studies comparing ABR and remplissage vs. ABR alone or the Latarjet procedure for anterior shoulder instability in patients with Hill-Sachs lesions were included. Clinical outcomes were compared, with all statistical analysis performed using Review Manager (version 5.3). P < .05 was considered statistically significant. RESULTS:Twelve clinical trials were included. There was a significant difference between ABR plus remplissage and ABR alone in total recurrence rate (3.2% vs. 16.8%, P < .05) but not the rate of revision due to recurrence (1.7% vs. 8.5%, P = .06). There was no significant difference between the Latarjet procedure and ABR plus remplissage in total recurrence rate (7.0% vs. 9.8%, P = .39), total revision rate (3.7% vs. 5.7%, P = .41), and rate of revision due to recurrence (1.6% vs. 2.1%, P = .79). There was a significantly lower rate of complications with ABR and remplissage compared with the Latarjet procedure (0.5% vs. 8.6%, P = .003). CONCLUSION/CONCLUSIONS:In patients with Hill-Sachs lesions and subcritical glenoid bone loss, ABR with remplissage resulted in lower rates of recurrent instability compared with ABR alone while resulting in similar recurrence rates, as well as similar patient-reported outcomes, with lower morbidity and fewer complications, compared with the Latarjet procedure.

INTRODUCTION/BACKGROUND:Burnout is an occupational hazard for physicians at all stages of training and medical practice. The purpose of the current study was to determine whether residency factors, with the use of an activity monitor, including the amount of exercise, have any impact on burnout among orthopaedic surgery residents in varying years of training. METHODS:Orthopaedic residents at a single institution were recruited immediately before beginning a new clinical rotation and followed for four weeks. On enrollment, the participants were given a wrist-worn activity monitor (Fitbit Flex) and instructed on its use for tracking physical activity. REDCap was used to collect burnout levels (as assessed by using the Maslach Burnout Inventory and the Patient Health Questionnaire-9), which were completed a total of five times, once at enrollment and weekly during the study period. RESULTS:Twenty-seven residents were enrolled, including 13 junior residents (interns and second years) and 14 senior residents (third, fourth, and fifth years). Seven residents were on fracture rotations, whereas 20 were not. As measured by using the Maslach Burnout Inventory, juniors were more emotionally exhausted (P = 0.01) and depersonalized (P = 0.027). No difference in the objective physical activity data as measured by using the Fitbit Flex and no difference in the self-reported hours of sleep were observed. Residents on orthopaedic trauma rotations also reported significantly higher rates of emotional exhaustion and depersonalization (P < 0.001) than other residents and were more physically active on average (P < 0.030). DISCUSSION/CONCLUSIONS:Although depersonalization and depression are common symptoms seen among orthopaedic surgery residents, this study demonstrated that quality of life improves markedly as they progress through their residency training. Residents on orthopedic trauma rotations have greater levels of emotional exhaustion and depersonalization. This pilot study suggests that burnout prevention programs should begin at the start of training to provide residents with strategies to combat and then reinforced while on orthopaedic trauma rotations. LEVEL OF EVIDENCE/METHODS:Level III Diagnostic Study.

PURPOSE/OBJECTIVE:In recent years, meniscal allograft transplantation (MAT) has been established as an effective option for young patients with symptomatic meniscus insufficiency with goals of functional improvement and joint preservation. Currently, there is little available information on return-to-play among patients in this cohort. The purpose of this study is to systematically review the literature and to evaluate the reported rehabilitation protocols, return-to-play guidelines, and subsequent rates of return-to-play following MAT. METHODS:MEDLINE, EMBASE and the Cochrane Library were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to find studies on MAT. Studies were included if they reported return-to-play data or rehabilitation protocols. The rate and timing of return-to-play was assessed. The rehabilitation protocols were recorded, including time to start range of motion (ROM), full ROM, partial weight bearing (WB), and full WB. RESULTS:Overall, 67 studies met the inclusion criteria. Eleven studies, including 624 patients, reported 483 out of 624 patients (77.4%) returning to play, with 326 out of a reported 475 patients (68.6%) returning to the same/higher level, at a mean time to return of 9.0 months. There was significant variability in the reported rehabilitation protocols, but the most commonly reported time to begin ROM exercises was within the first week by 42 out of 60 studies (70.0%) and full ROM at 8 weeks by 18 out of 46 studies (39.1%). Partial weight bearing was most commonly begun in the fourth week by 20 out of 46 studies (43.5%), and for full WB the sixth week by 43 out of 65 studies (66.1%). Time elapsed following surgery was the most commonly reported criteria for return-to-play by 44 out of 48 studies (91.6%), with 6 months being the most common time point utilized by 17 out of 45 studies (37.8%). A small proportion of studies, 16 out of 48 (33.3%), advised against returning to competitive/collision sports altogether following MAT. CONCLUSIONS:In conclusion, there is a high rate of return-to-play following MAT, with the majority of patients returning to the same level of play. However, there is significant variability in reported rehabilitation protocols, and poor-quality reporting in return-to-play criteria in the literature indicates a need for further study and the development of an evidence-based consensus statement for this patient population. The results from this study can be used to better inform patients on their expected outcomes and provide a more informed consent process. LEVEL OF EVIDENCE/METHODS:IV.

INTRODUCTION/BACKGROUND:The purpose of the current study was to evaluate resident, fellow, and attending perspectives on the use of e-learning as part of orthopaedic surgery education. METHODS:A survey was created evaluating (1) overall attitudes toward e-learning, (2) multi-institutional e-learning/e-conferences, (3) national/regional e-conferences, and (4) future directions with e-learning. The survey was distributed to all the orthopaedic surgery residency program directors in the United States, and they were asked to circulate the survey to their program's faculty and trainees. RESULTS:A total of 268 responses were collected, including 100 attendings and 168 trainees. Overall satisfaction with e-learning compared with in-person learning was higher among trainees than attending faculty, with 51.4% of trainees favoring e-learning, as opposed to 32.2% of attendings (P = 0.006). Both groups felt they were more likely to pay attention with in-person learning (P = 0.89). During the COVID-19 pandemic, 85.7% of residents have used e-learning platforms to join a conference in their specialty of interest while off-service. Most attendings and trainees felt e-learning should play a supplemental role in standard residency/fellowship education, with a low number of respondents feeling that it should not be used (86.6% versus 84%, and 2.1% versus 0.6%, respectively, P = 0.28). CONCLUSION/CONCLUSIONS:E-learning has been an important modality to continue academic pursuits during the disruption in usual education and training schedules during the COVID-19 pandemic. Most trainees and attendings surveyed felt that e-learning should play a supplementary role in resident and fellow education moving forward. Although e-learning does provide an opportunity to hold multi-institutional conferences and makes participation in meetings logistically easier, it cannot fully replicate the dynamic interactions and benefits of in-person learning.

PURPOSE/OBJECTIVE:This study systematically reviewed the literature for outcomes following revision surgery for a failed prior Latarjet procedure. METHODS:Two independent reviewers performed the literature search based on PRISMA guidelines using the EMBASE, MEDLINE, and The Cochrane Library databases. Studies in which the Latarjet procedure was performed as a revision procedure following failed prior shoulder instability surgery were included. Clinical outcomes analyzed were: 1. functional outcomes, 2. recurrent instability, 3. range of motion, and 4. COMPLICATIONS/RESULTS:Statistical analysis was performed using IBM SPSS. RESULTS:There were seven studies with 161 patients (162 shoulders) included. Four studies used a bone-block procedure, three used arthroscopic soft-tissue stabilization, and the mean follow-up was 49.8 months. The most commonly reported functional outcome measure was the Rowe score, with a weighted mean average of 79.7, with 82.9% of patients having good to excellent outcomes. Return to play was possible for 73.8% of patients, with 64.2% of those returning to at least the same level of competition. The overall recurrence rate was 9.5%, with 3.6% and 5.9% experiencing recurrent dislocations and subluxations, respectively. The overall revision rate was 4.2%, with all patients undergoing revisions due to recurrence. There were no reported neurovascular complications. Instability arthropathy was reported in 43.3% of patients. CONCLUSION/CONCLUSIONS:Surgical management following a failed Latarjet procedure results in moderate rates of recurrent instability and has a low intraoperative and postoperative complication rate. Additionally, the results across all techniques appear similar, with no procedure being identified as the gold-standard in the literature. However, there was a concerning rate of instability arthropathy, which may be related to the failure of a bony procedure.

BACKGROUND:Traumatic anterior shoulder instability is a common clinical problem among athletic populations, with several surgical treatment options available. The optimal treatment remains undetermined. Currently the main current treatment options are the Latarjet procedure or open or arthroscopic Bankart repair. The purpose of this study was to network meta-analyze the recent evidence to ascertain if the open Latarjet procedure and open or arthroscopic Bankart repair result in lower recurrence rates and subsequent revision procedures. The results were ranked with the P-score. METHODS:A literature search was performed based on the PRISMA guidelines. Cohort studies comparing any of the open Latarjet procedure and open or arthrosopic Bankart repair for anterior shoulder instability were included. Clinical outcomes were compared using a frequentist approach to network meta-analysis, with statistical analysis performed using R. RESULTS:Twenty-nine studies with 2,474 patients were included. The open Latarjet procedure resulted in lower rates of recurrent instability and revisions due to recurrence compared to both open and arthroscopic Bankart repairs. The open Latarjet procedure resulted in the highest rate of return to play. However, the open Latarjet procedure also resulted in the highest complication rate. CONCLUSION/CONCLUSIONS:Our network meta-analysis found the open Latarjet procedure had the lowest recurrence rates, lowest revisions rates, and highest rates of return to play in the surgical treatment of anterior shoulder instability. However, the Latarjet procedure has been shown to result in a higher complication rate, which needs to be considered when deciding which stabilization procedure to perform.

BACKGROUND:Patients with anterior cruciate ligament (ACL) injuries and reconstruction are at an increased risk of developing osteoarthritis requiring total knee arthroplasty (TKA). There have been few studies analyzing the impact of prior ACL reconstruction (ACLR) on surgical time and perioperative complications following TKA. PURPOSE/OBJECTIVE:The purpose of the current study was to compare surgical time and the rate of select early postoperative complications following TKA in patients with a history of ACLR to patients without prior ligament reconstruction. METHODS:We identified 116 patients who underwent TKA at our institution with a history of ACL reconstruction on the operative knee. These patients were propensity score matched to a control cohort of 348 patients undergoing TKA without a prior ACLR based on age, body mass index, sex, race, smoking status, surgeon, and year of surgery. Outcomes of interest for the current analysis were surgical time, incidence of postoperative wound complications, length of stay, discharge disposition, and 30-day readmission rate. RESULTS:There was no statistically significant difference between the ACLR and non-ACLR groups with respect to surgical time (108.23 ± 45.57 minutes vs. 102.72 ± 38.73 minutes, p = 0.205). There was also no significant difference in length of hospital stay, discharge disposition, incidence of postoperative wound complications, 30-day readmission rate, or reoperation rate. CONCLUSION/CONCLUSIONS:In this matched cohort analysis, we found no difference between patients undergoing TKA after ACLR and patients undergoing TKA for primary osteoarthritis with respect to perioperative complications and select postoperative outcomes, including the rate of reoperations. The current data demonstrates no significant impact of prior ACLR on the surgical time required to perform the arthroplasty.

PURPOSE/OBJECTIVE:The purpose of the current study is to meta-analyze the current evidence in the literature to compare arthroscopic Bankart repair versus conservative management for first-time anterior shoulder dislocation. METHODS:A literature search of MEDLINE, EMBASE and The Cochrane Library, was performed based on the PRISMA guidelines. Prospective studies comparing arthroscopic Bankart repair versus conservative management as treatment for first-time anterior shoulder dislocation were included. Recurrence, further treatment, and return to play were compared, with all statistical analysis performed using Review Manager Version 5.3. A p-value of < 0.05 was considered statistically significant. RESULTS:= 0, p = 0.002). CONCLUSION/CONCLUSIONS:Arthroscopic Bankart repair resulted in a 7-fold lower recurrence rate and a higher rate of return to play compared to conservative management. Thus, arthroscopic Bankart repair may be advisable to perform routinely for first-time dislocators who participate in sports.
