Abstract The purpose of this study was to compare basketball performance markers one year prior to initial severe lower extremity injury, including ankle, knee, and hip injuries, to one- and two-years following injury during the regular NBA season. Publicly available data were extracted through a reproducible extraction computed programmed process. Eligible participants were NBA players with at least three seasons played between 2008 and 2019, with a time-loss injury reported during the study period. Basketball performance was evaluated for season minutes, points, and rebounds. Prevalence of return to performance and linear regressions were calculated. 285 athletes sustained a severe lower extremity injury. 196 (69%) played one year and 130 (45%) played two years following the injury. Time to return to sport was similar between groin/hip/thigh [227 (88)], knee [260 (160)], or ankle [260 (77)] (P = 0.289). 58 (30%) players participated in a similar number of games and 57 (29%) scored similar points one year following injury. 48 (37%) participated in a similar number of games and 55 (42%) scored a similar number of points two years following injury. Less than half of basketball players that suffered a severe lower extremity injury were participating at the NBA level two years following injury, with similar findings for groin/hip/thigh, knee, and ankle injuries. Less than half of players were performing at previous pre-injury levels two years following injury. Suffering a severe lower extremity injury may be a prognostic factor that can assist sports medicine professionals to educate and set performance expectations for NBA players.
