Knee Extension and Knee Buckling After Total Knee Replacement

In the video, Anthony Maritato, PT, addresses a common concern related to the final degrees of knee extension. He begins by discussing a question he received from an individual who, despite having the range of motion, struggles with the strength in the last bit of knee extension. Tony delves into the potential causes of this issue, which could range from a mere strength deficit to more complex neurological problems. He emphasizes the mechanical challenges faced during this phase of extension, particularly highlighting the concept of "active insufficiency" where the quadricep muscle runs out of room, making the final stretch the most challenging.

To address this, Tony introduces a series of exercises designed to strengthen the knee and improve its range of motion. The primary exercise he suggests is the "Standing Closed Chain Position," where the individual gradually shifts their body weight onto the problematic leg while extending it. He also recommends a reverse motion exercise, emphasizing the importance of body weight positioning in facilitating knee movement. Throughout the video, Tony's approach is holistic, focusing not just on the physical exercises but also on understanding the underlying mechanics and challenges of knee extension. He concludes by encouraging viewers to share their experiences and solutions in the comments, fostering a sense of community and shared learning.
