Abstract
A retractor assembly may include a retractor removably coupled with a retractor handle. The retractor may include a handle connection feature, a retractor shaft, an arcuate projection having a convex retractor surface and a cutting shield surface, and a guide projection having an aperture shaped to receive at least a portion of a femoral condyle therein to position the retractor relative to a tibial plateau. The retractor handle may include a handle portion and a retractor connection feature. The retractor may be placed on a lateral side of a medial collateral ligament of a knee joint to retract the medial collateral ligament away from a tibial plateau of the knee joint and protect the medial collateral ligament during a tibial plateau resection procedure.

- a proximal end coupled to the distal end of the retractor shaft;
- a distal end distal to the proximal end;
- a superior surface;
- an inferior surface;
- a retractor surface extending intermediate the superior surface and the inferior surface, the retractor surface comprising a convex curvature;
- and
- a cutting shield surface located opposite the retractor surface and extending intermediate the superior surface and the inferior surface;
- and
- a guide projection coupled to the cutting shield surface, the guide projection comprising:
- a superior surface;
- an inferior surface;
- and
- an aperture formed through the guide projection between the superior surface and the inferior surface;
