Popis: | Purposes The goals of this work were to 1) determine the relationship between psychological readiness for return to sport and side-to-side symmetry during jump-landing in patients recovering from anterior cruciate ligament reconstruction (ACLR) and 2) determine whether psychological readiness for return to sport, graft type, meniscal pathology, sex, and time since surgery could predict landing symmetry in ACLR patients. Methods Thirty-eight patients recovering from primary unilateral ACLR (22 male/16 female; 19 patellar tendon autograft/19 hamstring autograft; age: 16.3 ± 1.9 years; 25.7 ± 6.2 weeks post-operative) completed the Anterior Cruciate Ligament Return to Sport after Injury (ACL-RSI) and ten bilateral stop-jumps. Three-dimensional lower extremity kinematics and kinetics were collected at 240 and 1920 Hz, respectively. Peak knee extension moment limb symmetry index (LSI) was computed during the first landing of the stop-jump. The relationship between the ACL-RSI and peak knee extension moment LSI was determined using Pearson correlations. Multivariate regression was used to determine the ability of the ACL-RSI, graft type, meniscal pathology, sex, time since surgery, stop jump entry speed, and jump height to predict knee extension moment LSI. Results There was a significant relationship between the ACL-RSI and peak knee extension moment LSI (r = 0.325; p = 0.047). The backward regression model found that 36.9% of the variance in knee extension moment LSI could be explained by the ACL-RSI (p = 0.040), graft type (p = 0.006), and jump height (p = 0.027). Conclusions There is a significant moderate association between psychological readiness for return to sport and asymmetric landing kinetics in patients following ACLR. Future work should investigate whether improving movement confidence results in improved kinetic landing symmetry. |
