Introduction
Posterior cruciate surgery generally refers to posterior cruciate ligament (PCL) reconstruction, and active knee bending usually means active flexion and extension of the knee joint. In general, patients can typically perform active knee flexion and extension by 6 weeks after PCL reconstruction, which is one step in the rehabilitation process. PCL reconstruction is a surgical procedure performed after a PCL rupture, using other tissues to reconstruct the ligament and restore its function.
Posterior cruciate ligament (PCL) reconstruction, commonly referred to as PCL surgery, generally involves reconstructing the torn posterior cruciate ligament using other tissues to restore its function. Active knee flexion and extension typically refers to voluntarily bending and straightening the knee joint. In general, patients can usually actively flex and extend their knee joint by 6 weeks after PCL reconstruction surgery, which is one step in the rehabilitation process. Specific details are as follows:
During PCL reconstruction, the ruptured ligament is replaced with graft tissue to restore stability and function. Within the first week after surgery, patients should remain on bed rest and use a knee brace to immobilize the joint. From 2 to 3 weeks post-surgery, patients can typically begin rehabilitation exercises, performing knee flexion and extension under brace protection, primarily focusing on active movements. Between 4 and 8 weeks after surgery, patients should generally achieve approximately 90 degrees of knee flexion during active exercises and may start walking with crutches. By 9 to 12 weeks post-surgery, patients can usually gradually return to normal daily activities. It is important to note that rehabilitation exercises must be performed under the guidance of a physician to avoid adverse outcomes.
Patients are advised to seek timely medical attention if discomfort occurs and to receive standardized treatment under professional medical supervision, which helps promote recovery.
