摘要Introduction: Persistent anterior knee pain is commonly observed after anterior cruciate ligament reconstruction, which is commonly associated with quadriceps wasting due to post-operative pathological muscle inhibition and disuse and possibly cause early patellofemoral joint osteoarthritis. A vicious cycle of quadriceps atrophy and weakness with PFJ pain may develop. We aim to identify the modifiable risk factors associated with anterior knee pain after ACL reconstruction.
Methods: Patients suffering from anterior knee pain and received arthroscopic assisted single-bundle ACL reconstruction using hamstrings graft for more than 5 years were retrospectively recruited. A thorough clinical history, physical examination, and basic radiographs were obtained. Outcome measures included leg quadriceps quality by ultrasound and functional scores (KOOS, Kujala, and IKDC).
Results: 19 patients were recruited. Quadriceps muscle atrophy and strength deficit were noted as shown by decreased quadriceps muscle thickness and increased quadriceps muscle stiffness Thinner vastus medialis and more stiffness in the vastus lateralis were observed in the affected knee. Patients also tended to shift their body weight towards the unaffected contralateral knee with increasing knee flexion due to the anterior knee pain. Compared with healthy individuals; components of the KOOS, Kujala, and IKDC scores were lower. Pain was also correlated with increased rectus femoris muscle stiffness.
Discussion and Conclusion: This study was able to identify details of persistent quadriceps muscle weakness which may lead anterior knee pain and possibly prevent the early development of patellofemoral joint osteoarthritis.
