Hinge knee replacement, also known as constrained knee replacement, is a specialized type of knee replacement used in cases of severe instability or ligament damage.
1
Preparation
Before surgery, anaesthesia is administered to ensure the patient's comfort.
2
Stabilization
The knee implant includes a hinge mechanism that provides stability in multiple directions, preventing excessive motion.
3
Indications
Hinge knee replacement may be recommended for patients with significant ligamentous laxity or those who have undergone previous unsuccessful knee replacements.
The hinge mechanism in the knee implant provides enhanced stability and prevents abnormal motion, reducing the risk of implant dislocation and instability.Hinge knee replacement restores stability and function to the knee joint, allowing patients to perform daily activities with greater ease and comfort. Hinge knee replacement is particularly beneficial for patients with severe ligament damage, joint deformity, or instability, where traditional knee replacement techniques may not provide adequate stability or function.
Rehabilitation
Comprehensive rehabilitation is essential for optimizing outcomes and restoring function following hinge knee replacement. Physical therapy focuses on strengthening muscles, improving joint stability, and maximizing range of motion, while also addressing any residual weakness or stiffness.
Monitoring
Patients undergoing hinge knee replacement require close monitoring for potential complications such as implant loosening, infection, or instability. Regular follow-up visits with the surgeon are scheduled to assess joint function, monitor implant stability, and address any concerns promptly.
Lifestyle Modification
Patients may need to make lifestyle modifications, such as avoiding high-impact activities or maintaining a healthy weight, to protect the newly replaced knee joint and optimize long-term outcomes. Adherence to prescribed activity restrictions and post-operative guidelines is essential for minimizing complications and promoting successful recovery.
