TKR - Technical considerations

AIMS     [Back To Top] 

1. Restoration of soft tissue balance of the knee to optimise the biomechanics of the knee

2. Restoration of the normal mechanical axis of the leg

Functional range of movement of the knee

Normal gait requires:

• 67 degrees of flexion in the swing phase

• 83 degrees of flexion for stair climbing

• 90 degrees of flexion for descending stairs

• 93 degrees of flexion in rising from a chair

EXPOSURE     [Back To Top] 

Skin Incision

• Longitudinal Midline or  Medial parapatellar skin incision

• In revision surgery, use the most lateral incision usable, as the superficial blood supply comes mainly from the medial side of the knee

Deep dissection
