Purpose To evaluate the outcomes of arthroscopic superior capsular reconstruction (SCR) and arthroscopy‐assisted lower trapezius tendon transfer (LTT) for posterosuperior irreparable rotator cuff tears (IRCTs). Methods Over an almost 6‐year period (October 2015 to March 2021), all patients who underwent IRCT surgery with a minimum 12‐month follow‐up period were identified. For patients with a substantial active external rotation (ER) deficit or lag sign, LTT was preferentially selected. Patient‐reported outcome scores included the visual analog scale (VAS) pain score, strength score, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, Single Assessment Numeric Evaluation (SANE) score, and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score. Results We included 32 SCR patients and 72 LTT patients. Preoperatively, LTT patients had more advanced teres minor fatty infiltration (0.3 vs 1.1, P = .009), a higher global fatty infiltration index (1.5 vs 1.9, P = .035), and a higher presence of the ER lag sign (15.6% vs 48.6%, P < .001). At a mean follow‐up of 2.9 ± 1.3 years (range, 1.0‐6.3 years), no differences in patient‐reported outcome scores were observed. Postoperatively, SCR patients had a lower VAS score (0.3 vs 1.1, P = .017), higher forward elevation (FE) (156° vs 143°, P = .004), and higher FE strength (4.8 vs 4.5, P = .005) and showed greater improvements in the VAS score (6.8 vs 5.1, P = .009), FE (56° vs 31°, P = .004), and FE strength (1.0 vs 0.4, P < .001). LTT patients showed greater improvement in ER (17° vs 29°, P = .026). There was no statistically significant between‐cohort difference in complication rate (9.4% vs 12.5%, P = .645) or reoperation rate (3.1% vs 10%, P = .231). Conclusions With adequate selection criteria, both SCR and LTT provided improved clinical outcomes for posterosuperior IRCTs. Additionally, SCR led to better pain relief and restoration of FE whereas LTT provided more reliable improvement in ER.

Introduction: To date, there has been a paucity of research evaluating the demographics, characteristics, and surgical training of orthopaedic residency program directors (PDs). Purpose: To determine the objective characteristics of orthopaedic residency PDs by analyzing their demographic characteristics, academic backgrounds, institutional histories, research productivity, and professional leadership affiliations. Methods: Data for each PD were collected by searching publicly available curriculum vitae , LinkedIn, Healthgrades, Doximity, and/or institutional biographies and consolidated into a database. Research productivities were collected by searching PubMed and Scopus. Results: Of the 210 PDs, 188 (89.5%) were male and 22 (10.5%) were female. One hundred seventy-four (82.9%) were non-Hispanic White, 14 (6.7%) Asian American and Pacific Islander, 12 (5.7%) Black or African American, 4 (1.9%) Hispanic or Latino, and 6 (2.9%) other/unknown. Twenty-four (11.4%) PDs had a military affiliation. Moreover, the most common subspecialties among orthopaedic PDs were orthopaedic traumatology (19.5%, n = 41), sports medicine (15.7%, n = 33), and hand surgery (11.9%, n = 25). The mean Scopus h -index, total number of publications at the time of data collection (June 2022), and total number of citations for all orthopaedic residency PDs were 10.5 ± 9.5, 33.9 ± 51.0, and 801.9 ± 1,536.4, respectively. Among all PDs, the mean tenure in the position was 8.9 ± 6.2 years to date, and the mean time from completion of residency to appointment as PD was 10.0 ± 6.2 years. Conclusions: Among orthopaedic surgery residency PDs, there is sparse female and minority representation. Overarchingly, orthopaedic PDs are White men in their early 50s. Moreover, 59.1% of PDs were appointed at an institution where they completed medical school, residency, or fellowship. orthopaedic traumatology (19.5%), sports medicine (15.7%), and hand surgery (11.9%) were the subspecialties most represented in current orthopaedic surgery PDs. Clinical Relevance: This study outlines important demographic characteristics among orthopaedic surgery residency PDs. Level of Evidence: III

Purpose To evaluate the cost‐effectiveness of 3 isolated meniscal repair (IMR) treatment strategies: platelet‐rich plasma (PRP)–augmented IMR, IMR with a marrow venting procedure (MVP), and IMR without biological augmentation. Methods A Markov model was developed to evaluate the baseline case: a young adult patient meeting the indications for IMR. Health utility values, failure rates, and transition probabilities were derived from the published literature. Costs were determined based on the typical patient undergoing IMR at an outpatient surgery center. Outcome measures included costs, quality‐adjusted life‐years (QALYs), and the incremental cost‐effectiveness ratio (ICER). Results Total costs of IMR with an MVP were $8,250; PRP‐augmented IMR, $12,031; and IMR without PRP or an MVP, $13,326. PRP‐augmented IMR resulted in an additional 2.16 QALYs, whereas IMR with an MVP produced slightly fewer QALYs, at 2.13. Non‐augmented repair produced a modeled gain of 2.02 QALYs. The ICER comparing PRP‐augmented IMR versus MVP‐augmented IMR was $161,742/QALY, which fell well above the $50,000 willingness‐to‐pay threshold. Conclusions IMR with biological augmentation (MVP or PRP) resulted in a higher number of QALYs and lower costs than non‐augmented IMR, suggesting that biological augmentation is cost‐effective. Total costs of IMR with an MVP were significantly lower than those of PRP‐augmented IMR, whereas the number of additional QALYs produced by PRP‐augmented IMR was only slightly higher than that produced by IMR with an MVP. As a result, neither treatment dominated over the other. However, because the ICER of PRP‐augmented IMR fell well above the $50,000 willingness‐to‐pay threshold, IMR with an MVP was determined to be the overall cost‐effective treatment strategy in the setting of young adult patients with isolated meniscal tears.

» Lateral epicondylitis (LE) or tennis elbow is a common cause of elbow pain in the general population, especially women in the fourth and fifth decades of life who participate in repetitive forceful movements involving the wrist and forearm. » The pathogenesis of this overuse injury is believed to start from an overload event leading to a microtear in or near the origin of the extensor carpi radialis brevis that is subsequently prone to additional injury and structural weakness over time. » Treatment of LE often begins with a wide variety of nonoperative modalities including rest, nonsteroidal anti-inflammatory drugs, bracing, and physical therapy. For recalcitrant symptoms, additional nonoperative therapies are implemented; however, there remains a lack of comparative efficacy between these adjunct treatments. » In this article, we examine the available literature regarding nonoperative management of LE and provide supplementary insight into the effectiveness of current modalities.

» Hamstring injuries are common among active and athletic individuals, especially those involved in high-speed running, distance running, or sports requiring sudden directional changes. Acute hamstring strains often occur as an eccentric strain during running or a stretch-type injury caused by simultaneous hip flexion and knee extension. Proximal hamstring tendinopathy is an overuse injury of the hamstring tendon as a result of chronic cicatrization of the musculotendinous unit. » Repeated stress to the hamstring tendon leads to increased cellularity of tendon fibers, disruption of collagen, and subsequent microinjury of the tissue that attaches the tendon to bone. » Management of hamstring injuries generally begins with nonoperative modalities consisting of eccentric rehabilitative exercise programs. Although various other treatment modalities are available, the comparative efficacy of these supportive measures is not well differentiated at this time. » In this article, we review the current literature with regard to the nonoperative treatment of hamstring injuries, specifically focusing on acute hamstring muscle strains and proximal hamstring tendinopathy in order to provide supplementary insight on the effectiveness of current modalities.

AbstractMean, median, and mode are among the most basic and consistently used measures of central tendency in statistical analysis and are crucial for simplifying data sets to a single value. However, there is a lack of understanding of when to use each metric and how various factors can impact these values. The aim of this article is to clarify some of the confusion related to each measure and explain how to select the appropriate metric for a given data set. The authors present this work as an educational resource, ensuring that these common statistical concepts are better understood throughout the Orthopedic research community.

Objectives:Introduction: Wrestling is a physically demanding sport with young athletes prone to anterior cruciate ligament (ACL) injuries. However, there is a paucity of data evaluating the results of ACL reconstruction (ACLR) in this cohort. Purpose: To assess patient-reported outcomes, reoperation rates, graft survival, and return to play (RTP) following ACLR in a large cohort of competitive wrestlers Methods: All competitive wrestlers (high school, collegiate, or professional) with a history of an ACLR at a single institution between 2000 and 2019 were retrospectively identified. Graft failure was defined as a re-tear determined by clinical or advanced imaging evaluation, and/or revision ACL reconstruction. All patients were contacted for determination of reinjury rates, current sport status, visual analog scale (VAS), International Knee Documentation Committee (IKDC) and Tegner activity scores. Results: 118 knees in 114 wrestlers were included at a median follow-up time of 5.8 years (IQR: 3.6 – 10.3). The median age was 17 years (15 – 18) with 116 (98%) males. ACLR was most often performed with bone-patellar tendon-bone (BTB) autograft (n = 64; 54%) or hamstring tendon (HT) autograft (n = 43; 36%). At final follow-up, 80% of athletes were able to RTP at a median of 273 days (IQR: 203 – 379). Graft failure occurred in 17 (14%) patients at a median time of 1.4 years (IQR: 0.8 – 4.7) after the index ACLR. BTB autograft demonstrated a lower failure rate compared to HT autograft (8% vs. 21%; P = 0.044). Kaplan-Meier survivorship free from graft failure for the entire cohort was 95.3% at 1 year, 92.5% at 2 years, 89.8% at 5 years, 84.6 at 10 years, 77.6 at 20 years. BTB autograft was associated with better survival than HT autograft up to 15 years after the index ACLR (90.4% vs. 76.3%; P = 0.030). Conclusions: Return to competitive wrestling was observed in 80% of athletes after ACLR, with 14% of wrestlers experiencing graft failure. BTB autograft reconstruction may serve as a more durable graft for competitive wrestlers with lower rates of failure when compared to HT autograft even up to 15 years after surgery.

Background: The extent to which concussions affect Women’s National Basketball Association (WNBA) athletes has not been thoroughly examined. Purpose: To evaluate the incidence and impact of concussion injuries occurring in the WNBA. Study Design: Descriptive epidemiology study. Methods: Publicly available records were searched to identify all documented basketball-related concussions from WNBA seasons 1997 to 2020. Player demographics, injury details, and basketball career information were collected. Concussion incidence and return-to-play (RTP) timing were evaluated before and after the institution of the WNBA concussion protocol in 2012. Minutes per game and game score per minute were compared 5 games before and 5 games after the concussion was sustained. Player game availability and RTP performance were also compared with an age-, body mass index–, position-, and experience-matched control group of players who did not sustain any injuries during the index season. Results: A total of 70 concussions among 55 players were reported in the WNBA from 1997 to 2020, with a mean incidence of 2.9 ± 2.3 concussions per season. After the implementation of the WNBA concussion protocol, the incidence significantly increased from 1.7 to 5.0 concussions per season ( P < .001). All players returned after a first-time concussion, missing a mean of 3.8 ± 4.7 games and 17.9 ± 20.7 days. After the adoption of the concussion protocol, the time to RTP significantly increased with games missed ( P = .006) and days missed ( P = .006). Minutes per game and game score per minute were not significantly affected by sustaining a concussion ( P = .451 and P = .826, respectively). Conclusion: Since the adoption of the WNBA concussion protocol in the 2012 season, the incidence of concussions increased significantly. Athletes retained a high rate of RTP after missing a median of 4 games, and the time to RTP increased after the institution of the concussion protocol. Player game availability and performance within the same season were not significantly affected by concussion injuries after a successful RTP.

AbstractIntroduction Second anterior cruciate ligament (SACL) injuries are a devastating complication following return to sport (RTS). Appropriate and safe RTS criteria that reduce the risk of SACL injuries are needed. The goal of this study was to investigate the relationship between functional and isokinetic testing at 6 months following primary ACL reconstruction (ACLR) as risk factors for SACL injuries.Methods Patients with primary ACLR from 1990 to 2010 were identified. Those with 6-month postoperative functional and isokinetic testing and a minimum of 2-year follow-up were included. Functional testing included vertical jump, single-leg hop, and single-leg triple hop. Isokinetic testing included concentric quadriceps and hamstrings (HSs) strength at 60 and 180 degree/s speeds. Statistical analysis evaluated the significance of the various tests between those with and without a secondary tear.Results In total, 344 patients with a mean age of 26.0 ± 9.8 years at an average time of 9.1 ± 3.5 years of follow-up were analyzed. Fifty-nine patients (17%) experienced SACL injuries at an average time of 4.8 years following ACLR with 34 (58%) ipsilateral graft ruptures and 25 (43%) contralateral tears. Several isokinetic measures were significantly different between the NO SACL and the SACL groups: quadriceps 60 degree/s limb symmetry index (LSI) (75 vs. 82% p = 0.01), HS 60 degree/s LSI (92 vs. 97%, p = 0.04), quadriceps 180 degree/s involved/body weight (BW) (41 vs. 47%, p = 0.04), and HS 180 degree/s involved/BW (30 vs. 34%, p = 0.04). Patients with involved limb peak quadriceps torque value greater than 65 or 50% of BW (60 and 180 degree/s) had a 2.2 and 3.1 times higher risk of an SACL injury.Conclusions Patients with certain elevated isokinetic scores in the injured limb at 6 months after ACLR experienced a higher rate of subsequent ACL injuries than those who had lower peak torque. Although a quantitative only analysis may not be sufficient to determine RTS criteria, clinicians should caution high-performing patients about the risk of subsequent ACL injury.Level of Evidence Cohort study; 3.

Purpose To evaluate the efficacy of an automated pneumatic torniquet pump and its ability to automatically calculate the limb occlusion pressure (LOP), as compared with the manual Doppler ultrasound technique. Methods Participants presenting to a Sports Medicine clinic were evaluated for study enrollment. Participants were fitted with a pneumatic tourniquet for the upper and lower extremity. LOP measurements were taken with a Doppler ultrasound or automated SmartCuffs PRO device in a randomized order. Results Final analysis was performed on 96 limbs (48 upper extremities and 48 lower extremities). The study population had a mean age 37.1 ± 14.7 years old and a mean body mass index of 25.47 ± 3.80. The mean measured LOP pressure on the upper extremity with Doppler ultrasound was 174.0 ± 48.7 mm Hg with a range from 120 to 282 mm Hg, whereas the mean measured LOP by the automated pump was 184.0 ± 44.9 mm Hg with a range from 135 to 266 mm Hg. There was no statistically significant difference found between the Doppler LOP and the Smart Cuff upper extremity LOP ( P = .29). When evaluating LOP pressure on the lower extremity the mean LOP found with the Doppler ultrasound was 195.0 ± 31.9 mm Hg with a range from 160 to 272 mm Hg, whereas the automated pump the mean LOP was 205.0 ± 27.1 mm Hg with a range from 168 to 278 mm Hg. There was no statistically significant difference found between the Doppler LOP and the automated pump lower extremity LOP ( P = .09). Conclusions No difference in the personalized LOP measurement was found when comparing an automated pump with the current gold standard of manual Doppler ultrasound. No patients companied of pain or discomfort during the LOP measurement. Level of Evidence Level II, diagnostic: prospective cohort study.
