摘要： A patella resection and replacement device comprising a pliers-like clamp for gripping and holding the patella, the clamp having a spring biased hinge bolt. A specially designed drill guide may be snapped into place and removed from the hinge bolt without releasing the patella during surgery. Similarly, a specially designed patella button presser may be snapped into place and removed from the hinge bolt. Without the necessity of releasing, re-gripping and re-orienting the patella during the process, the time for the operation is greatly reduced.
