The biomechanics of the knee and surgical possibilities of healing osteoarthritic knee joints.

Osteoarthritis of the knee is generally focused around areas of stress concentration. Osteotomy and tibial tubercle elevation can bring about functional healing. Surgical success depends upon a correct preoperative biomechanical evaluation of the affected knee and upon effective surgical reduction of the stress concentration. Careful attention to the details of biomechanical principles and orthopedic management induces healing and correction of many extremely deformed and unstable knee joints.
