Background:Women’s National Basketball Association (WNBA) players have a greater incidence of lower extremity injury compared with male players, yet no data exist on functional outcomes after Achilles tendon rupture (ATR).Purpose:To evaluate the effect of Achilles tendon repair on game utilization, player performance, and career longevity in WNBA athletes.Study Design:Cohort study; Level of evidence, 3.Methods:WNBA players from 1997 to 2019 with a history of ATR (n = 12) were matched 1:2 to a healthy control group. Player characteristics, game utilization, and in-game performance data were collected for each athlete, from which the player efficiency rating (PER) was calculated. Statistical analysis was performed comparing postinjury data to preinjury baseline as well as cumulative career data. Changes at each time point relative to the preinjury baseline were also compared between groups.Results:Of the 12 players with ATR, 10 (83.3%) returned to play at the WNBA level at a mean (±SD) of 12.5 ± 3.3 months. Four players participated in only 1 WNBA season after injury. There were no differences in characteristics between the 10 players who returned to play after injury and the control group. After return to play, the WNBA players demonstrated a significant decrease in game utilization compared with preinjury, playing in 6.0 ± 6.9 fewer games, starting in 12.7 ± 15.4 fewer games, and playing 10.2 ± 9.1 fewer minutes per game ( P < .05 for all). After the index date of injury, the players with Achilles repair played 2.1 ± 1.2 more years in the WNBA, while control players played 5.35 ± 3.2 years ( P < .01) Additionally, the players with Achilles repair had a significant decrease in PER in the year after injury compared with preinjury (7.1 ± 5.3 vs 11.0 ± 4.4; P = .02). The reduction in game utilization and decrease in PER in these players was maintained when compared with the matched controls ( P < .05 for both).Conclusion:The majority of WNBA players who sustained ATR were able to return to sport after their injury; however, their career longevity was shorter than that of healthy controls. There was a significant decrease in game utilization and performance in the year after return to play compared with healthy controls.

Background: National Basketball Association (NBA) players who return to sport (RTS) after Achilles tendon rupture have been reported to have poor outcomes. Purpose: To evaluate the effect of Achilles tendon ruptures on player performance and career longevity in NBA athletes. Study Design: Cohort study; Level of evidence, 3. Methods: NBA players who sustained Achilles tendon ruptures between 1970 and 2019 were identified using publicly available resources and were matched 1:1 to a healthy control group by age, position, height, and body mass index. Demographic characteristics, player utilization (games and minutes), and performance efficiency rating (PER) were documented for all athletes. The season of Achilles tendon rupture was set as the index year, and statistical analysis compared postindex versus preindex data both acutely and in the long term. Percentages relative to preoperative values were calculated to compare the injured and control groups in a standardized fashion. Results: Of 47 players, 34 (72.3%) with Achilles tendon ruptures returned to play at the NBA level after surgical intervention. A total of 7 players were excluded from the study. No differences were found in demographic characteristics or PER (2 years before injury) between the remaining 27 players and matched controls. The injured players had significantly shorter careers compared with control players (3.1 ± 2.3 vs 5.8 ± 3.5 seasons, respectively; P < .05). Injured players demonstrated significant declines in games per season (GPS), minutes per game (MPG), and PER at 1 year and 3 years after RTS compared with preindex baseline ( P < .05). Injured players, compared with control players, had reduced relative percentages of games started (GS) (50% vs 125%, respectively), MPG (83% vs 103%), and PER (80% vs 96%) at 1 year after return ( P < .05), but reductions at extended 3-year follow-up were seen only in GPS (71% vs 91%) and GS (39% vs 99%) ( P < .05). Conclusion: Our study found that 72.3% of NBA players returned to play after Achilles tendon repair, but they had shorter careers compared with uninjured controls. Players returning from Achilles tendon repairs had decreased game utilization and performance at all time points relative to their individual preindex baseline. However, for the injured players when compared with controls, game utilization but not performance was found to be decreased at 3-year follow-up.

Background: The purpose of this study was to determine the return-to-play (RTP) rate and postinjury performance after Achilles tendon (AT) ruptures in National Football League (NFL) skill position players. Methods: The study included NFL skill positions with an AT rupture between the 2009-2010 and 2015-2016 seasons. Performance data were collected and compared against a matched control group. RTP was defined as playing in at least 1 game after repair. Results: RTP rate was 57% for the study cohort. The tight ends (TEs) had the highest RTP rate at 71% while the wide receivers (WRs) had the lowest RTP rate at 38%. Compared with the control group, WRs with successful RTP had significantly less receptions per game ( P = .01). For defensive players with RTP there were significant decreases in postrepair performance in tackles, passes defended, and fumbles forced/recovered compared with the control group. Conclusion: A total of 57% of players achieved RTP with WRs and running backs (RBs) having the lowest RTP rates and TEs and linebackers (LBs) having the highest RTP rates. RBs, defensive backs (DBs), and LBs with successful RTP had decreased performance in all categories. This updated information may be helpful for athletes, physicians, scouts, and coaches in evaluating players with a history of AT rupture. Levels of Evidence: Analytic, level 3, retrospective cohort study, Epidemiologic study

Background: Achilles tendon rupture (ATR) is a potentially career-ending injury in professional athletes. Limited information exists regarding return to play (RTP) in professional soccer players after this injury. Purpose: To determine the RTP rate and time in professional soccer players after ATR and to evaluate player performance relative to matched controls. Study Design: Cohort study; Level of evidence, 3. Methods: We evaluated 132 professional soccer players who suffered an ATR between 1999 and 2018. These athletes were matched 2:1 to uninjured controls by position, age, season of injury, seasons played, and height. We collected information on the date of injury, the date of RTP, and player performance metrics (minutes played, games played, goals scored, assists made, and points per game) from official team websites, public injury reports, and press releases. Changes in performance metrics for the 4 years after the season of injury were compared with metrics 1 season before injury. Univariate comparisons were performed using independent-sample, 2-group t tests and Wilcoxon rank-sum tests when normality of distributions was violated. Results: The mean age at ATR was 27.49 ± 4.06 years, and the mean time to RTP was 5.07 ± 2.61 months (18.19 ± 10.96 games). The RTP rate was 71% for the season after injury and 78% for return at any timepoint. Overall, 9% of the injured players experienced a rerupture during the study period. Compared with controls, the injured players played significantly less (-6.77 vs -1.81 games [ P < .001] and -560.17 vs -171.17 minutes [ P < .05]) and recorded fewer goals (-1.06 vs -0.29 [ P < .05]) and assists (-0.76 vs -0.02 [ P < .05]) during the season of their Achilles rupture. With the exception of midfielders, there were no significant differences in play time or performance metrics between injured and uninjured players at any postinjury timepoint. Conclusion: Soccer players who suffered an ATR had a 78% RTP rate, with a mean RTP time of 5 months. Injured players played less and demonstrated inferior performance during the season of injury. With the exception of midfielders, players displayed no significant differences in play time or performance during any of the 4 postinjury seasons.

Category: Sports; Trauma Introduction/Purpose: For the professional athlete, an Achilles tendon rupture is a devastating and potentially career ending injury. Basketball players with Achilles tendon injuries have among the lowest reported return to play rates for orthopaedic injuries. Among National Basketball Association (NBA) players, Achilles rupture has been shown to result in difficulty with returning to competition and significantly decreased productivity exhibiting a large effect size (0.95). Comparable data regarding Women’s National Basketball Association (WNBA) players is lacking. This study evaluated the impact of Achilles tendon rupture on return to play and post-injury performance among WNBA players in order to test the null hypothesis of equal negative impact as observed in the NBA. Methods: This was an IRB exempt retrospective matched cohort study. Public records indicated 12 WNBA players incurred Achilles tendon ruptures between the 2006 and 2018 seasons. Demographic data and performance statistics were collected for pre and post-injury seasons. A control cohort was matched for age, height, weight, years of experience in WNBA, position, and pre-injury player efficiency rating (PER). Individual pre versus post injury and injury cohort versus control cohort performance statistics were compared using paired and independent samples t-tests, respectively. Injury effect size on performance was calculated. The primary outcome was difference in PER. Secondary outcomes included differences in itemized performance statistics. A priori sample size based on effect size of 0.95 indicated that 12 players per cohort were needed for 80% power to detect a difference in PER at alpha of 0.05. Results: 7 (58%) players returned to WNBA play by mean 9.5 months. There was no significant difference in pre injury PER from seasons matched for years of WNBA experience between cohorts (13.7 vs 11.9; P = 0.6). Mean PER significantly decreased in the first year (13.66 vs 9.00; P = .04; Cohen’s d = .99) and approached a significance difference in the second year (14.56 vs 9.95; P = 05; Cohen’s d = 1.02) in the injured cohort only. Minutes per game (MPG) significantly decreased only year 1 post-injury (25.84 vs 19.54; P = .04; Cohen’s d = 6.56). Points per game (PPG), field goals attempted per game (FGA), and free throws attempted per game (FTA) significantly decreased in both years post-injury (all p < 0.05). Conclusion:: WNBA players incurred Achilles tendon ruptures at a rate of 2% annually. This was associated with a moderate rate of return to play and significantly reduced production (PER, MPG, PPG, FGA, and FTA) in the first year. The second season following injury found players returning closer to pre-injury performance, with persistent significant reduction in PPG, FGA, and FTA. Effect sizes were uniformly large. These data were consistent with NBA results, supporting the null hypothesis. Providers may use this data to counsel high and elite level female basketball players on return to play and performance expectations following Achilles tendon ruptures.

Category: Ankle, Sports Introduction/Purpose: While much less common than ankle sprains and other sports injuries, Achilles tendon ruptures have represented unexpected and potentially career-altering injuries for professional football athletes in the National Football League (NFL). Over the past decade, the technique for surgical repair of the ruptured Achilles tendon has evolved. Mini-open and percutaneous techniques have become more common, allowing for the minimization of wound complications and expediting the rehabilitation of athletes. Therefore, the objectives of this study were to update the epidemiology of Achilles tendon ruptures in the NFL, and to analyze how recovery and post-injury performance of professional football players with this injury have progressed in the last two decades. Methods: Several online sources including NFL news and injury reports, player registries, and player statistic databases were cross-referenced to conduct a retrospective identification of all NFL players sustaining complete Achilles tendon ruptures during the 2010-2015 NFL seasons. Yearly player performance statistics were also obtained and recorded for both offensive and defensive players. A power rating formula and “approximate value” algorithm, commonly used to evaluate player production, were borrowed to calculate yearly Offensive and Defensive performance metrics for each injured player. These calculated measurements were used to quantify both offensive and defensive player performance up to 3 seasons before and after their respective Achilles tendon rupture injuries, allowing for each player to serve as his own control. Results: 78 Achilles tendon ruptures were identified in professional football players during the 2010-2015 NFL seasons. 58% of these injuries occurred during the preseason. Of those that suffered an Achilles tendon rupture, 26% did not ever return to play in the NFL. Players who did return to play in the NFL took an average of 9 months to recover after the date of injury. Across all positions, there was a net decrease in power ratings by 22% and a net decrease in approximate value by 23% over 3 years following player return after Achilles tendon rupture. Across all positions, running backs saw the biggest decrease in production with a 78% decrease over 3 years post-injury in both power ratings and approximate value. Conclusion: While the incidence of Achilles tendon ruptures in NFL players, especially in the preseason, has increased substantially, more players are returning to play after injury and with better post-injury performance as compared to the previous two decades. These injuries should still be considered potentially career-altering as 26% of players never return to play after Achilles tendon ruptures and there is still a net decrease in power-ratings by 22% for those who do return. However, these numbers optimistically suggest that advancements in treatment protocol and rehabilitation are resulting in faster recovery and improved performance after Achilles tendon ruptures in NFL players.

Background: Achilles tendon ruptures are devastating in elite athletes. There are currently no studies examining the effects of Achilles tendon rupture on performance outcomes in the Women’s National Basketball Association (WNBA). Hypothesis: Athletes in the WNBA who sustained an Achilles tendon rupture and underwent subsequent surgical repair will sustain declines in performance metrics when compared with their preinjury statistics and matched controls. Study Design: Cohort study; Level of evidence, 3. Methods: Seventeen WNBA players who sustained an Achilles tendon rupture from 2000 to 2019 were identified through publicly available injury reports and player profiles. Athlete information collected included age, body mass index, position, and service in the WNBA when the tear occurred. Statistics were collected for 1 season before and 2 seasons after the injury, and the player efficiency rating (PER) was calculated. Players were matched to uninjured controls by service in the WNBA, position, and performance statistics. Results: On average, players were 28 years of age at the time of Achilles tendon rupture, with a service time in the WNBA of 6.5 years. Four players never returned to play in the WNBA, while 7 players failed to play more than 1 season. Players who did return played significantly fewer minutes per game compared with preinjury in both postinjury seasons 1 and 2 (mean difference, –6.11 and –6.54 min/game, respectively; P < .01 for both) and had a significantly decreased PER in postinjury season 2 (mean difference, –2.53; P = .024). After returning to play, the injured players experienced significant decreases when compared with controls in field goals (–0.85 vs +0.20; P = .047), free throws (–1.04 vs +0.12; P < .01), steals (–0.48 vs +0.24; P = .018), and points scored (–2.89 vs +0.58; P = .014). Conclusion: WNBA players experienced significant decreases in performance metrics after Achilles tendon rupture compared with their preinjury levels and compared with uninjured controls. Overall, 23.5% of players failed to return to the WNBA, while 41.2% failed to play for more than 1 season.

Background: Athletes in the Women’s National Basketball Association (WNBA) and National Basketball Association (NBA) are subject to high injury rates given the physical demands of the sport. Comprehensive data regarding injury patterns and rates in these athletes are limited. Purpose: To summarize available data on orthopaedic and sports medicine–related injuries through 2020 in professional female and male basketball players. Study Design: Systematic review; Level of evidence, 4. Methods: A search was conducted using PubMed and Embase through April 5, 2020, to identify injury studies regarding WNBA and NBA players. Studies were included if the injury or surgery was considered a direct consequence of game play including musculoskeletal/orthopaedic, concussion, ophthalmologic, and craniomaxillofacial injuries. Systematic reviews, screening studies, or studies without sufficient WNBA or NBA player subgroup analysis were excluded. Results: A total of 49 studies met inclusion criteria, 43 (87.8%) of which detailed musculoskeletal injuries. The lower extremity represented 63.3% of studies. A majority (59.2%) of studies were level 4 evidence. The source of data was primarily comprehensive online search (n = 33; 67.3%), followed by official databases (n = 11; 22.4%). Only 3 studies concerned WNBA athletes compared with 47 that concerned NBA athletes. The lowest return-to-play rates were cited for Achilles tendon repairs (61.0%-79.5%). Variability in return-to-play rates existed among studies even with similar seasons studied. Conclusion: The majority of literature available on orthopaedic and sports medicine–related injuries of NBA and WNBA athletes is on the lower extremity. The injuries that had the greatest effect on return to play and performance were Achilles tendon ruptures and knee cartilage injuries treated using microfracture. The reported outcomes are limited by heterogeneity and overlapping injury studies. There are limited available data on WNBA injuries specifically.

Background: Early functional mobilization (EFM) may improve patient outcome after Achilles tendon rupture (ATR). However, whether EFM affects patient outcome via changes in tendon elongation, thickening, or calf muscle atrophy is unknown. Purpose: To analyze differences in tendon and muscle morphology recovery over time between groups treated with EFM or standard treatment after ATR repair. Study Design: Cohort study; Level of evidence, 2. Methods: This prospective cohort study included 86 patients (20 women) with ATR repair who had a mean (SD) age of 39.3 (8.2) years and were part of a larger prospective randomized controlled trial. Patients were postoperatively randomized to immediate postoperative weightbearing and ankle motion (EFM group) or to immobilization in a below-knee plaster cast for 2 weeks (control group). Patient-reported and functional outcomes were assessed at 6 and 12 months with the Achilles Tendon Total Rupture Score and the heel-rise test for endurance. At 2 and 6 weeks and 6 and 12 months postoperatively, B-mode ultrasound imaging was performed to assess the length and cross-sectional area (CSA) of the Achilles tendon, the gastrocnemius CSA, as well as the thickness of soleus. Results: The Achilles Tendon Total Rupture Score for the EFM and control groups were 65.8 (18.7) and 56.8 (20.1; P = .045), respectively, at 6 months and 79.6 (15.8) and 78.9 (17.2; P = .87), respectively, at 12 months. At 2 weeks, tendon elongation was significantly more pronounced in the EFM group as compared with the control group (mean side-to-side difference, 1.88 cm vs 0.71 cm; P = .005). Subsequently, tendon elongation increased in the control group while it decreased in the EFM group so that at 6 and 12 months no significant differences between groups were found. Mean Achilles tendon elongation at 1 year was 1.73 (1.07) cm for the EFM group (n = 55) and 1.67 (0.92) cm for the control group (n = 27), with a mean difference of 0.06 cm (95% CI, 0.54 to –0.42; P = .80). Achilles tendon CSA and calf muscle atrophy displayed no significant differences between the groups; however, significant changes were demonstrated over time ( P ≤ .001) in both groups. Conclusion: EFM results in more Achilles tendon elongation at early healing, but this difference subsides over time. EFM does not seem to affect patient outcome via changes in tendon elongation, thickening, or calf muscle atrophy. Registration: NCT02318472 (ClinicalTrials.gov identifier).

Background: Functional deficits and health-related impairments are common after an Achilles tendon rupture (ATR). Rehabilitation protocols vary greatly, and few studies have allowed loading in combination with ankle motion immediately after surgery (ie, early functional mobilization [EFM]). It is unclear whether EFM may counteract the negative impact of ankle immobilization after an ATR. Purpose: The primary aim of this study was to assess the efficacy of EFM compared with standard treatment (ie, 2 weeks of unloading in a plaster cast followed by 4 weeks of weightbearing in an orthosis) regarding patient-reported and functional outcomes in patients with an ATR after acute operative repair. The secondary aim was to explore whether the occurrence of deep venous thrombosis (DVT) during the 2 postoperative treatments affected outcomes. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 135 patients who underwent ATR repair, randomized to either EFM, including immediate postoperative loading and ankle motion, or standard treatment, were evaluated with functional tests and 5 self-administered outcome questionnaires at 6 and 12 months postoperatively. Results: At 6 months, the EFM group scored higher on the RAND 36-Item Health Survey (RAND-36) questionnaire subscales of general health and vitality ( P < .05) compared with the control group. No significant differences between the groups were found on disease-specific questionnaires (Achilles tendon Total Rupture Score [ATRS] and Foot and Ankle Outcome Score [FAOS]). At 12 months, no significant differences on any of the patient-reported outcome measures or the functional heel-rise test were seen between the groups. The RAND-36 subscale of general health, however, exhibited higher values in the EFM group (82.6 ± 16.9) than the control group (77.1 ± 17.0) ( P = .051) at 12 months after the injury. Patients sustaining DVT postoperatively had lower self-reported outcomes on the ATRS, FAOS, and RAND-36 questionnaires at 6 and 12 months compared with patients not having sustained DVT (all P < .05). Conclusion: This study demonstrated that an accelerated postoperative protocol with immediate loading and ankle motion resulted in better general health and vitality at 6 months. However, there were no differences between the groups in the recovery of heel-rise function. Future studies should focus on the means to reduce the risk of DVT to improve patient outcomes after ATR.
