Understanding Knee-Crooking After Knee Replacement Surgery: Causes, Symptoms, and Treatment Options

Knee-crooking is a term used in the context of knee replacement surgery. It refers to the tendency of the prosthetic knee joint to bend or flex excessively, leading to an unnatural gait and potentially causing discomfort, pain, or instability.

Knee-crooking can occur due to various factors, such as:

1. Improper alignment of the prosthetic components: If the prosthetic knee joint is not properly aligned with the thigh and shin bones, it can lead to excessive flexion or bending of the knee joint.
2. Loose or worn-out implants: Over time, the prosthetic components can loosen or wear out, causing the knee joint to move excessively.
3. Muscle imbalance: Weak or tight muscles around the knee can cause the prosthetic joint to move in an unnatural way, leading to knee-crooking.
4. Poor posture or gait: Abnormal walking patterns or poor posture can put excessive stress on the prosthetic knee joint, leading to knee-crooking.

Knee-crooking can be treated in various ways, including adjusting the prosthetic components, tightening or replacing loose implants, strengthening muscles around the knee, and improving posture or gait. In severe cases, revision surgery may be necessary to correct the issue.
