Primary Knee Symposium: Biomechanical Considerations in the Knee

The Complex Primary Knee – Kenneth Greene, MD

Dr. Greene discussed the factors he believes contribute to making a primary knee more difficult. They include:

• Uncorrectable deformity > 15-20°
• Extra-articular deformities
• Flexion contracture
• Pre-existing hardware
• Difficult exposures

Dr. Greene reviewed potential exposure problems PSlide A and then discussed ways to avoid the non-standard exposure. PSlide B He elaborated by going over difficult exposure techniques PSlide C then highlighted his summary points. PSlide D

He then discussed flexion contracture, reviewing pre-operative planning, PSlide E surgical rationale, PSlide F and surgical technique. PSlide G He summarized his main points on flexion contracture. PSlide H

Dr. Greene went on to discuss hardware PSlide I and dealing with soft tissues PSlide J. He reviewed when to do a corrective osteotomy in a TKA with extra-articular deformity. PSlide K

His presentation summary points are outlined in PSlide L.
