Economic and Performance Analysis of Achilles Tendon Rupture in the National Basketball Association.

Background: Achilles tendon ruptures are common and potentially career-ending injuries for National Basketball Association (NBA) players. Many studies have reviewed the impact of Achilles tendon ruptures on return to play (RTP) and performance, but there are no studies on their economic significance. Purpose/Hypothesis: This study aimed to analyze the economic and performance consequences of Achilles tendon ruptures usingthe cost of recovery (COR) for NBA franchises as well as preinjury salary/career success. It was hypothesized that players with higher preinjury salaries or performance would have an increased COR, higher rates of RTP, and more career success after their injury. Study Design: Descriptive epidemiology study. Methods: Publicly available data of NBA players who sustained an Achilles tendon rupture between 1990 and 2023 were analyzed. Data were retrospectively gathered by R software code to include players' ages, positions, salaries, pre- and postinjury player efficiency rating, time missed after injury, and RTP. Performance impact was measured by advanced statistics: player efficiency rating, Win Shares per 48 Minutes, and Value Over Replacement Player. Two groups of 3 cohorts were created: All-Star, Starter, and Reserve versus group A (<$3,999,999), group B (≥$3,999,999 to ≤$8,999,999), and group C (>$8,999,999). Analysis of variance with post hoc Tukey tests for continuous data and Fisher exact tests for categorical data was used. Significance levels were set at Results: A total of 37 players met the inclusion criteria and played between the years of 1992 through 2019. The mean COR that NBA teams faced was $4 million per player. The cumulative economic loss from Achilles tendon ruptures in the NBA between 1992 and 2019 was $117,578,851. Overall RTP was 78.38%, and 31.03% of players who returned to play were out of the NBA within 3 years. RTP to the highest playing level was highest in group B (45.5%), followed by group A (40%) then group C (12.5%). The COR of All-Star players, Starter players, and Reserve players averaged $5.7 million, $3.4 million, and $3 million, respectively. Conclusion: This study investigated the financial and performance implications of Achilles tendon ruptures among NBA athletes. Most players struggled to restore their preinjury performance, except for Reserve players. The findings provide valuable insights into the complexities of COR and postinjury performance.
