An in vitro study of potential attachment sites for the reconstruction of the medial collateral ligament of canine stifles
Rupture of the medial collateral ligament (MCL) results in joint instability of the stifle in dogs and should be surgically repaired as early as possible. Placement of a prosthetic ligament in the most isometric position is necessary to maintain joint stability avoiding excessive tension or loosenin...
