PURPOSE/OBJECTIVE:The purpose of this study was to systematically review and analyze the current evidence in the literature to determine the relative complication rates of the singleincision versus dual-incision approach to distal biceps tendon repair. METHODS:The literature search was performed based on the PRISMA guidelines. Cohort studies comparing the single-incision or dual-incision approach to biceps tendon repair alone were included. Clinical outcomes were compared, with all statistical analysis performed using Review Manager Version 5.3. A p-value < 0.05 was considered to be statistically significant. RESULTS:Twelve clinical studies with varying levels of evidence (LOE I: 1, LOE II: 1, LOE III: 10) with 2,429 patients were included. Overall, there was a significantly lower rate of total complications with the dual-incision approach (16.1% vs. 23.1%, p < 0.01) and a lower rate of neurological injuries (9.1% vs. 24.1%, p < 0.01). There was a lower rate of lateral antebrachial cutaneous nerve injuries with the dual-incision approach (5.2% vs. 19.5%, p < 0.01), and superficial radial nerve injuries (2.5% vs. 4.8%, p < 0.01), but there was no significant difference in the rate of posterior interosseous nerve injuries (2.2% vs. 1.2%, p = 0.20). There was a significantly lower rate of heterotopic bone formation with the single-incision approach (1.3% vs. 2.7%, p = 0.01). CONCLUSION/CONCLUSIONS:The dual-incision approach decreases the risk of total, overall postoperative complications and sensory nerve injuries following distal biceps repair. However, it has a higher risk of heterotopic bone formation.

As the world continues to battle the COVID-19 pandemic, health care providers are committed to providing care not only to our patients but also to our community. Schools in New York City (NYC) went remote on March 15, 2020. This can prove detrimental to student development and education. Numerous leaders in education and public health have noted that the remote learning will further widen educational and income disparities in those from underserved and underrepresented areas. A group of orthopedic residents who attended NYC public schools and were current house staff at a major academic tertiary medical center in NYC developed and implemented a virtual high-school mentorship program. This program incorporated weekly lectures and discussions given by health care providers to students interested in health care from NYC public high schools. The goal of this program was to provide mentorship during the COVID pandemic to a high-school audience where greater than 80% of students are considered to be living below the poverty level. Although school is now back in session, these programs should be continued in person. It is the aim of the authors that other orthopedic residents and health care providers implement similar programs in their communities.

PURPOSE/OBJECTIVE:Over 200,000 anterior cruciate ligament (ACL) reconstructions are performed in the US each year. The recovery process following surgery can be slow and difficult with patients suffering persistent strength and endurance deficits. Testosterone is an important anabolic hormone responsible for maintenance and development of muscle mass. While the response of the hypothalamic-pituitary axis (HPA) to surgery has been investigated, no studies exist tracking the HPA response, specifically that involved in testosterone homeostasis, to ACL reconstructions. The purpose of this study was to explore the response of endogenous testosterone production after ACL reconstruction and determine a possible correlation between perioperative testosterone levels in males and postoperative strength and clinical outcomes. METHODS:This was a single-center, prospective observational study measuring preoperative and postoperative testosterone levels. Plasma testosterone, follicle stimulating hormone (FSH), and lutenizing hormone (LH) were measured before 10:30 am on the day of surgery. These were then checked at the same time of day at 1 week, 6 weeks, and 12 weeks postoperatively. Patients were also evaluated with the visual analog scale for pain (VAS), Tegner, and Lysholm scales preoperatively and at postoperative visits. Statistical analysis was performed using ANOVA and were considered significant at p < 0.05. RESULTS:Twenty male patients with a mean age of 34.0 ± 9.2 years undergoing ACL reconstruction were enrolled between October 2017 and April 2018. Results showed a decrease in testosterone (3.7 ng/mL vs. 2.9 ng/mL, p = 0.05), free testosterone (8.2 pg/mL vs. 6.8 pg/mL, p = 0.05), and follicle stimulated hormone (1.8 mIU/mL vs. 1.7 mIU/ mL, p = 0.83) between the preoperative plasma draw and 1-week postoperative follow-up visit. Luteinizing hormone (1.1 mIU/mL vs. 1.5 mIU/mL, p = 0.11) increased postoperatively. By week 6, testosterone returned to baseline (3.7 ng/mL vs. 3.9 ng/mL), while free testosterone continued to increase through week 12. Lutenizing hormone peaked at the 1-week postoperative visit and trended downward until week 6 (1.5 mIU/mL vs. 1.4 mIU/mL, p = 0.79). Follicle stimulating hormone continued to increase after the week-1 visit through week 12. Patient reported outcomes exhibited a trend similar to hormone levels, with the lowest patient reported outcome (PRO) scores reported at week 1 and a constant trend upward. Although there were similar trends, there were no significant correlations between change in hormone levels and change in PRO scores. CONCLUSION/CONCLUSIONS:Our study emphasizes the crucial period of hormonal decrease and their return to baseline. This knowledge will contribute to the understanding and timing of hormone therapy supplementation. Short-term testosterone replacement may be beneficial to return patients to work and physical activity at a faster rate.

Purpose/UNASSIGNED:The purpose of this study was to assess the rate of hospital admissions, inpatient conversions, reoperations, and complications associated with tibial tubercle osteotomies (TTO), high tibial osteotomies (HTO), and distal femoral osteotomies (DFO) performed at our ambulatory surgery center compared with our inpatient hospital facility. Methods/UNASSIGNED:value of <0.05 was considered to be statistically significant. Results/UNASSIGNED: = .698, respectively). Conclusions/UNASSIGNED:Osteotomies about the knee performed in an ambulatory setting were safe, with no difference in readmission, reoperation, or postoperative complications compared to those performed at an inpatient hospital. Additionally, no patient required conversion from an outpatient to an inpatient setting. Level of Evidence/UNASSIGNED:Level III, retrospective comparative study.

Purpose/UNASSIGNED:To determine whether an association exists between the presence of cervical spine pathology and postoperative patient-reported outcomes (PROs) in patients undergoing open subpectoral biceps tenodesis (BT). Methods/UNASSIGNED:text, Fisher exact test, or analysis of variance. Results/UNASSIGNED: = .046). There were no significant differences between groups' ASES, baseline VAS, overall satisfaction scores, and willingness to undergo the same operation again. No significant differences were found in postoperative rate of return to sport, time to return, and return to preoperative competitiveness. Conclusions/UNASSIGNED:Patients with SLAP tears undergoing isolated BT in the presence of cervical spinal stenosis may have inferior Subjective Shoulder Value, Shoulder Instability-Return to Sport after Injury, and VAS during sport scores as compared with controls, although many PROs were similar at follow-up. Athletes undergoing BT, particularly with concomitant cervical spine pathology, should be counseled appropriately before surgery. Level of Evidence/UNASSIGNED:Level III, case-control study.

BACKGROUND/UNASSIGNED:Multiple surgical options exist for the treatment of patellar instability; however, the most common procedures involve either a reconstruction of the medial patellofemoral ligament (MPFL) or a repair/plication of the MPFL and medial soft tissues. PURPOSE/UNASSIGNED:To perform a network meta-analysis of the randomized controlled trials (RCTs) in the literature to compare MPFL reconstruction, MPFL repair, and nonoperative management for patellar instability. STUDY DESIGN/UNASSIGNED:Systematic review and network meta-analysis; Level of evidence, 1. METHODS/UNASSIGNED:scores. RESULTS/UNASSIGNED:score for all outcomes in those with first-time dislocation. CONCLUSION/UNASSIGNED:The current study demonstrated that MPFL reconstruction results in the lowest rate of recurrent patellar instability and best functional outcomes as measured using the Kujala score.

PURPOSE/OBJECTIVE:The purpose of this study was to evaluate the mid-term results of posterior medial meniscal root tear (PMMRT) repair through assessment of functional outcome scores and magnetic resonance imaging (MRI). METHODS:This was a single-center, retrospective study evaluating patients that had undergone a PMMRT. This was a follow-up to a previously published 2-year outcome study (all original patients were invited to participate). Clinical outcomes included pre- and postoperative International Knee Documentation Committee (IKDC) and Lysholm scores. Root healing, meniscal extrusion, and cartilage degeneration via International Cartilage Repair Society Scale (ICRS) grades were assessed on MRI by two musculoskeletal fellowship-trained radiologists. RESULTS:10 of the original study's 18 patients were able to participate. Mean age and BMI was 48.4 ± 12.0 years and 29.5 ± 4.5, respectively, with mean follow-up 65.5 ± 8.3 months (range 52.0-75.8) (60% female). The IKDC significantly increased from 43 ± 13 preoperatively to 75 ± 16 at 5-year follow-up (p < 0.001). There was no significant change in IKDC score between 2-year and 5-year follow-up [75 ± 16 vs 73 ± 20, (n.s)]. The Lysholm also significantly increased between preoperative and 5-year follow-up (49 ± 7 vs 84 ± 11, p < 0.001). There was no significant change between Lysholm score at 2-year and 5-year follow-up [84.0 ± 11 vs 82 ± 13, (n.s)]. Mean extrusion did not significantly change from the preoperative state to 5-year follow-up [4.80 mm ± 1.9 vs 5.0 mm ± 2.5, (n.s.)]. Extrusion also did not significantly change between 2-and 5-year follow-up [6.1 ± 3.2 mm vs 5.0 mm ± 2.5, (n.s.)]. No patients with > 3 mm of extrusion on preoperative MRI had < 3 mm of extrusion on postoperative MRI. Both medial femoral condyle and medial tibial plateau ICRS grades significantly increased from preoperative to 2-year follow-up (p = 0.038, p = 0.023, respectively). Medial femoral condyle and medial tibial plateau ICRS grades again significantly increased between 2-year and 5-year follow-up (p = 0.014, p = 0.034). CONCLUSION/CONCLUSIONS:Patients treated with the transtibial suture pullout technique with two locking cinch sutures had maintenance of clinical outcome improvements at 5-year follow-up. However, extrusion was widely prevalent, with worsening progression of femoral and tibial chondral disease. LEVEL OF EVIDENCE/METHODS:Level 4.

Objectives: The purpose of the current study was to evaluate the clinical outcomes and rates of return to play in patients who underwent an osteochondral allograft (OCA) procedure for a symptomatic osteochondral defect in the knee.
Method(s): A retrospective review of patients who underwent an OCA for an osteochondral defect of the knee, between June 2011 and March 2019 was performed. Return to play, the level of return and the timing of return were assessed. Additionally, the reasons for being unable to return were evaluated. A p-value of < 0.05 was considered to be statistically significant.
Result(s): Overall, there were 103 patients who underwent OCA at our institution and met our inclusion and exclusion criteria. The mean age was 31.8 +/- 11 years, and 63.9% were male, with a mean of 44.2 +/- 23.3 month follow-up. The overall rate of return to play was found to be 63.1% (N=65), while the rate of RTP at the same or higher level was 32.0% (N = 33). With respect to the patients who were unable to return to their desired sport, reasons cited included pain in the operative knee (N = 18, 47.3%), physical inability to perform in the desired sport (N = 8, 21.1%), and fear of re-injury (N = 6, 15.8%).
Conclusion(s): Overall, there was a poor rate of return to play following OCA. Additionally, the majority of patients were unable to return to play at their pre-injury level

Objectives: The purpose of the current study was to investigate clinical outcomes in overhead athletes undergoing biceps tenodesis for the treatment of symptomatic, isolated SLAP tears involving the biceps-labral complex.
Method(s): A retrospective review of overhead athletes who underwent biceps tenodesis for a SLAP tear was performed. The American Shoulder & Elbow Surgeons (ASES) score, Visual Analogue Scale (VAS), Subjective Shoulder Value (SSV), patient satisfaction, willingness to undergo surgery again, revisions, and return to play (RTP) were evaluated. Psychological readiness to return to sport was evaluated using the SLAP-Return to Sport after Injury (SLAP-RSI) score. A p value of <0.05 was considered to be statistically significant.
Result(s): The current study included 44 overhead athletes. The mean age was 34.9 (16-46), 79.5% were males, and the mean follow-up was 49 months (18-107). Overall, we found that 81.8% of patients returned to play their overhead sport following biceps tenodesis, and 59.1% of patients returned to the same or higher level of play. It took patients on average 8.7 months to return to play following biceps tenodesis. The mean SLAP-RSI score was 69.3, and 70.5 % of patients passed the SLAP-RSI threshold of 56. The mean scores for ASES, VAS, SSV, and satisfaction were 92, 0.8, 80.5, and 87.9%, respectively. No patients in our cohort required a revision surgery.
Conclusion(s): This study found that athletes undergoing biceps tenodesis as the treatment for a symptomatic, isolated SLAP tear had a high rate of return to play, good functional outcomes, and a low rate of revision surgery

BACKGROUND:Patient-reported allergies (PRAs) are often stigmatized as a potential nonmodifiable risk factor for increased pain and worse functional outcomes following surgery. However, there is a dearth of literature directly assessing the impact of PRAs on outcomes in sport surgeries such as medial patellofemoral ligament reconstruction (MPFLR). The purpose of our study was to determine whether PRAs were associated with worse outcomes following MPFLR. METHODS:We conducted a retrospective review of patients who underwent MPFLR at our institution from 2011 to 2019. Patients were included if they had at least 12 months of follow-up. PRAs were obtained from preoperative medical assessments and categorized by drug class. Demographic and perioperative data were obtained from electronic medical records. Postoperative outcomes were measured using a telephone survey and included recurrent instability, Visual analog scale (VAS) for pain, VAS for sports, Kujala score, MPFL-Return to Sport after Injury (MPFL-RSI) score, and overall satisfaction score. Multiple linear regression was used to determine association between PRAs and outcome measures, and p-values less than 0.05 were considered significant. RESULTS:The cohort included 141 MPFLR. Most patients were female (98, 70%) with an average age of 25 years (range 12-56 years). Average follow-up time was 47 months. Forty-seven patients (33%) reported at least one PRA. There were no significant differences in postoperative pain, functional outcomes, satisfaction, or return to sport between patients with or without PRAs (all p > 0.05). Absence of antibiotic PRAs was predictive of higher VAS (p < 0.007), but there were no other differences. There were no significant differences in outcomes between patients without PRAs, PRAs without a concomitant psychiatric disorder, or PRAs with a concomitant psychiatric disorder (all p > 0.05). CONCLUSIONS:In conclusion, PRAs with or without concomitant psychiatric diagnoses are not associated with worse postoperative pain, functional outcomes, or satisfaction following MPFLR with allograft, dispelling common misconceptions that increased number of allergies or psychiatric diagnoses lead to inferior surgical outcomes. Presence of antibiotic allergies was associated with lower VAS postoperative pain score. Future research should investigate the relationship between PRAs and other surgeries in the field of sports medicine.
