Abstract
Background National Basketball Association (NBA) and Women's National Basketball Association (WNBA) players with Achilles tendon ruptures have previously been noted to have a significant decline in performance post-injury. There has been recent anecdotal evidence that elite players with dominant Achilles tendon ruptures may be able to return at a higher level of play post-rupture. Objective This study aimed to evaluate for any differences in performance in higher-performing NBA and WNBA players with dominant versus non-dominant Achilles tendon ruptures pre- and post-injury. Methods This study was conducted at the University of Pennsylvania, Department of Physical Medicine and Rehabilitation. NBA and WNBA players with an Achilles tendon rupture from 1990 to 2020 were identified. Only elite players, indicated by an average player efficiency rating (PER) of >15 in either of the three seasons pre/post-injury, were included. The average PER, offensive rating, defensive rating, and usage percentage were compared in the three seasons pre- and post-injury. Results Eighteen players met the inclusion criteria, and nine each were classified as dominant and non-dominant Achilles tendon ruptures based on their primary shooting hand. There was no significant difference between the dominant and non-dominant rupture groups in any outcomes pre-injury, including age. The non-dominant cohort had a significant decline in PER (20.04 vs. 14.16; p < 0.001) and offensive rating (110.33 vs. 101.56; p = 0.004) post-injury. There was no significant difference observed post-injury in defensive rating or usage percentage. The dominant cohort had no significant difference in any outcomes post-injury, returning to the same level of play as pre-injury. Despite no difference existing between the groups at baseline, the dominant group performed significantly better post-rupture with regard to PER (19.56 vs. 14.16; p < 0.001) and offensive rating (114.00 vs. 101.56; p < 0.001) versus the non-dominant group. Conclusion Elite NBA and WNBA players with dominant Achilles tendon ruptures had no change in performance post-injury, returning to the same level of production as pre-injury. Post-rupture, they demonstrated notably superior outcomes versus the non-dominant group with regard to PER and offensive rating. The non-dominant rupture group experienced the same decline in PER and offensive rating post-injury observed in previous studies. The data indicate that elite NBA and WNBA players with a dominant Achilles tendon rupture have a much more favorable recovery post-injury and are able to return to the same level of performance.

Abstract
INTRODUCTION Athletes in the National Basketball Association (NBA) are subjected to high levels of mechanical stress increasing their risk of injury. The purpose of this study was to see how certain lower extremity injuries affect in-game performance in relation to each NBA athlete's demographics. The hypothesis was that NBA players' post-injury performance would differ depending on their demographics and the type of injury sustained. METHODS Descriptive epidemiology study of NBA injury list designations from the 2010/2011 season to the 2018/2019 season. About 255 lower leg injuries that met the inclusion criteria were selected from the injury lists spanning from the 2010/2011 season to the 2018/2019 season. These included ligamentous knee injuries, knee sprains, knee strains, knee hyperextensions, patellar injuries, ankle injuries, and Achilles injuries. The change in performance was determined by comparing mean game scores before and after injury with single-tailed, heteroscedastic t-testing and 95% confidence intervals for mean values. RESULTS An overall statistically significant decrease in mean game score from 9.82 to 8.75 was seen in all included players (p = 0.01). Only athletes taller than the mean height (199.85 cm; p = 0.01) and heavier than the mean weight (101.63 kg; p = 0.02) showed a significant decline in performance. Ankle and knee injuries both resulted in a significant loss in game score (p = 0.04), with ankle injuries resulting in a greater average decline (-1.76 post-injury) than knee injuries (-1.34 post-injury). CONCLUSIONS These findings suggest that treatment regimens should reflect the type of injury and demographics of the specific NBA player injured. Further research is warranted to determine if treatment may be more efficacious when streamlined based on player size and injury type.

Abstract
Background Establishing evidence-based recommendations specific to female athletes has been overlooked in sports medicine. Achilles tendon rupture is one of the most common musculoskeletal injuries, occurring in 15 to 55 per 100 000 people annually. Differences in injury rates could be due to hormonal effects, as estrogen receptors have been identified in tendons along with decreased tendon strain based on oral contraceptive use. The primary purpose of this study was to audit the representation of female athletes in the literature regarding Achilles repair. Methods An electronic search was performed using PubMed to identify articles related to Achilles repair using the protocol by Smith et al. Studies were assessed by population, size, athletic caliber, study impact, research theme, and menstrual status. Results Female representation across all studies was 1783 of 10 673 subjects (16.7%). Composition of included studies was predominantly mixed-sex cohorts with 131 of 169 (77.5%) included studies. Within mixed-sex cohort studies, the total representation of female athletes was 1654 of 8792 participants (18.9%). Thirty-two studies were male only, constituting 1540 participants, whereas 3 studies were female only composed of 86 athletes. Importantly, the disparity between male and female representation worsened as the athletic caliber of the study population increased, with 5.0% female representation in studies with professional athletes. No study collected data related to menstrual status and its potential relationship to Achilles rupture or postoperative outcomes. Conclusion Mixed-sex cohort studies underrepresented female athletes, and male-only cohort studies were more common than female-only studies. These findings indicate a need for increased representation of female athletes as well as acknowledgment of menstrual status in research related to Achilles repair. Future studies should focus on representation of female athletes and data collection related to sex-specific hormones, hormonal contraceptive use, and menstrual status to improve treatment of Achilles tendon ruptures for female athletes. Level of Evidence Level IV, case series.

Abstract
PURPOSE Patient-related outcome measures (PROMs) are important instruments to evaluate efficacy of orthopaedic procedures. The Achilles tendon Total Rupture Score (ATRS) is a PROM developed to evaluate outcomes after treatment of Achilles tendon ruptures (ATRs). Purpose of this study is to develop and culturally adapt the German version of the ATRS and to evaluate reliability and validity. METHODS The ATRS was translated by forward-backward translation based on common guidelines. In this retrospective study, 48 patients with a surgical intervention after ATR were recruited. Reliability was evaluated by intraclass correlation coefficient (ICC) and Cronbach's alpha. Construct validity was valued by determining Pearson correlation coefficient with the German version of the Foot and Ankle Outcome Score (FAOS) and the Victorian Institute of Sports Assessment-Achilles questionnaire (VISA-A). RESULTS The German Version of the ATRS has an excellent internal consistency (Cronbach's alpha 0.96) as well as an excellent test-retest-reliability (ICC 0.98). It has a moderately strong correlation with the VISA-A (r = 0.73) as well as with the FAOS subclasses (r = 0.6-0.79). CONCLUSION The German version of the ATRS demonstrated good psychometric properties. It proofed to be a valid and reliable instrument for use in patients with Achilles tendon Rupture.

Abstract
Achilles tendon (AT) injury is one of the most common tendon injuries, especially in athletes, the elderly, and working-age people. In AT injury, the biomechanical properties of the tendon are severely affected, leading to abnormal function. In recent years, many efforts have been underway to develop effective treatments for AT injuries to enable patients to return to sports faster. For instance, several new techniques for tissue-engineered biological augmentation for tendon healing, growth factors (GFs), gene therapy, and mesenchymal stem cells were introduced. Increasing evidence has suggested that GFs can reduce inflammation, promote extracellular matrix production, and accelerate AT repair. In this review, we highlighted some recent investigations regarding the role of GFs, such as transforming GF-β(TGF-β), bone morphogenetic proteins (BMP), fibroblast GF (FGF), vascular endothelial GF (VEGF), platelet-derived GF (PDGF), and insulin-like GF (IGF), in tendon healing. In addition, we summarized the clinical trials and animal experiments on the efficacy of GFs in AT repair. We also highlighted the advantages and disadvantages of the different isoforms of TGF-β and BMPs, including GFs combined with stem cells, scaffolds, or other GFs. The strategies discussed in this review are currently in the early stages of development. It is noteworthy that although these emerging technologies may potentially develop into substantial clinical treatment options for AT injury, definitive conclusions on the use of these techniques for routine management of tendon ailments could not be drawn due to the lack of data.

Abstract
Achilles tendon rupture is among the most common sports injuries. In patients with high functional demands, surgical repair is preferred to facilitate early return to sporting function. This article reviews the literature and provides evidence-based guidance for return to sport after operative management of Achilles tendon rupture. A search was performed using PubMed, Embase and Cochrane Library for all studies reporting on return to sport after operative management of Achilles tendon rupture. The review included 24 studies reporting on 947 patients, and found that 65-100% of patients were able to return to sport between 3 and 13.4 months post-injury, with incidence of rupture recurrence 0-5.74%. These findings will help patients and healthcare professionals plan a recovery timeline, discuss athletic functionality post-recovery, and understand complications of repair and risk of tendon re-rupture.

Abstract
PURPOSE The purpose of this study was to translate and cross-culturally adapt the Achilles Tendon Total Rupture Score (ATRS), a patient-reported outcome measurement (PROM) designed specifically to assess outcomes in patients with Achilles tendon rupture, into the Thai language and then determine its validity and reliability. METHODS The ATRS was translated into the Thai version (Thai-ATRS) according to internationally recognized guidelines. The study included 50 patients with Achilles tendon rupture from 2003 to 2017. The web-based online assessments were conducted two weeks apart. Construction validity was determined by assessing the correlation between the Thai-ATRS and the Thai version of the Foot and Ankle Outcome Score (Thai-FAOS). Reliability was determined with Cronbach's alpha and intraclass correlation coefficients (ICC). RESULTS The validity test displayed a strong correlation between the Thai-ATRS and the Thai-FAOS (r = 0.87). The reliability test showed good internal consistency with a Cronbach's alpha of 0.95 and excellent internal consistency with an ICC of 0.95, which represented excellent test-retest reliability. The MDC was 10.7 at the individual level and 1.5 at the group level. CONCLUSION The Thai-ATRS was demonstrated to be valid and reliable for assessing functional outcomes in Thai patients with Achilles tendon rupture. LEVEL OF EVIDENCE II.
