After ACL surgery, patients often experience difficulty lifting their leg due to muscle weakness and decreased strength. This is caused by compensatory mechanisms that occur when the knee's natural stability is compromised. Physical therapy plays a crucial role in improving muscle strength and joint mobility. A rehabilitation program should be tailored to individual needs and pace progress gradually to avoid over-ambition. Patients may also experience emotional stress, which can be managed through self-examination techniques and seeking emotional support. With patience and dedication, patients can achieve optimal recovery and a healthier path forward.
