股四头肌力量不对称在重建前十字韧带(ACL)后恢复运动参与时会导致功能变差和着陆模式不对称，但对纵向结果的影响尚不清楚。这项研究确定了年轻运动员在恢复运动时股四头肌力量不对称的前交叉韧带重建后，是否会在5年后表现出膝关节软骨退化的标志，与那些恢复运动时股四头肌力量对称的运动员相比。参与者(n=27)在体检合格时登记参加体育运动(基线测试)，并跟踪观察5年。在基线时，测量双侧股四头肌力量，并使用肢体对称指数将队列分为两组：高股四头肌力量恢复运动间隙(rts-HQ；肢体对称指数≥90%)和低股四头肌力量恢复运动间隙(rts-lq；肢体对称指数lt；85%)。基线5年后，收集定量磁共振成像(MRI)(T2松弛时间(Ms)：累及膝关节内侧/外侧股骨髁和胫骨平台)的数据。组间差异采用独立样本t检验进行评估。恢复运动后5年，RTS-LQ力量组(n=14)股骨外侧髁前部T2松弛时间较RTS-HQ力量组(n=13)延长。
Quadriceps femoris strength asymmetry at the time of return to sports participation after anterior cruciate ligament (ACL) reconstruction contributes to worse function and asymmetric landing patterns, but the impact on longitudinal outcomes is not known. This study determined if young athletes after ACL reconstruction with quadriceps femoris strength asymmetry at return to sports clearance would demonstrate markers of knee cartilage degeneration 5 years later compared to those with symmetric quadriceps femoris strength at return to sports. Participants (n=27) were enrolled at time of medical clearance for sports participation (baseline testing) and followed for 5 years. At baseline, quadriceps femoris strength was measured bilaterally and a limb symmetry index was used to divide the cohort into 2 groups: return to sport clearance with high quadriceps femoris strength (RTS-HQ; limb symmetry index≥90%) and return to sport clearance with low quadriceps femoris strength (RTS-LQ; limb symmetry index<85%). At 5 years post-baseline, quantitative magnetic resonance imaging (MRI) (T2 relaxation times (ms): involved knee medial/lateral femoral condyle and tibial plateau) data were collected. Group differences were evaluated with independent samples t-tests. At 5-years post-return to sports, the RTS-LQ strength group (n=14) demonstrated elevated T2 relaxation times at the anterior region of the lateral femoral condyle compared to the RTS-HQ strength group (n=13).
