How Long Is Physical Therapy After Knee Replacement: A Comprehensive Guide

Knee replacement surgery, also known as knee arthroplasty, is a common procedure performed to alleviate pain and restore function in individuals with severe knee joint damage. While the surgery itself is crucial, the road to recovery extends beyond the operating room. Physical therapy plays a vital role in helping patients regain strength, mobility, and flexibility post-surgery. In this article, we will explore the duration of physical therapy after knee replacement and answer some commonly asked questions regarding the rehabilitation process.

The duration of physical therapy after knee replacement can vary depending on several factors, including the individual’s overall health, the extent of the surgery, and the rehabilitation goals. On average, patients should expect to engage in physical therapy for approximately 6 to 12 weeks following knee replacement surgery. However, it is important to note that each patient’s recovery timeline may differ.

During the initial phase of physical therapy, which typically lasts for the first few weeks, the focus is on reducing pain, swelling, and inflammation while regaining range of motion in the knee joint. This is achieved through gentle exercises, manual therapy, and modalities such as ice and compression. As the healing progresses, the rehabilitation program advances to include strengthening exercises and functional activities that mimic daily life tasks.
