Knee muscle strength after quadriceps tendon autograft anterior cruciate ligament reconstruction: systematic review and meta-analysis.

摘要: Restoration of knee muscle strength is associated with better outcomes following anterior cruciate ligament (ACL) reconstruction, but little known about the outcome quadriceps tendon autograft (QT) ACL reconstruction in relation to other graft types. The aim this review was evaluate extensors and flexors QT compared (1) non-reconstructed contralateral limb (2) alternative Four electronic databases were searched up until 21st February 2020. Summary meta-analyses performed comparing by way symmetry index (LSI). Comparative grafts for two most frequently reported measures which peak extensor torque LSI, flexor LSI at post-operative periods: 3, 5–8, 9–15, 24, 36–60 months. In total, 18 studies met inclusion criteria. Knee 952 reconstructions included either or 1 4 types; 245 hamstring (HT), 143 patellar (PT), 45 allograft, 21 tibialis allograft. did not reach 90% even 24 months post-operatively. Conversely, exceeded 9–15 months period. 5–8 months appears similar PT weaker than HT reconstruction. addition, significantly greater patients patients. decision utilize a should include consideration outcomes. recovery be restored before 24 months.
