The varus knee has a bunch of bone and ligament abnormalities that needs to be addressed to right the deformity. The mechanical axis of the femur is tilted medially relative to the lengthy axis of the tibia. The distal femoral floor frequently is still in valgus alignment to the lengthy axis of the femur. lots of the varus deformity is brought on by deficiency within the medial tibial plateau. The deep and superficial medial collateral ligaments are gotten smaller and deformed by way of osteophytes.

However, in most cases it is necessary to strip the posterior portion from its attachments as well. Ligament Balancing In Total Knee Varus Knee 51 Fig. 84. If the knee remains tight medially in extension after release of the anterior medial collateral ligament fibers, then the posterior fibers are released. Here the curved half-inch osteotome is passed under the released anterior fibers and angled downward 45° to release the posterior oblique fibers of the medial collateral ligament. The medial collateral ligament maintains loose attachment to the pes anserinus, and the distal periosteal attachments to the ligament remain intact as well, so the knee does not become grossly lax as a result of this procedure.
The "liga-ments are released according to their function at each position. The medial collateral ligament (deep and superficial layers) attaches to the medial epicondylar area through a broad band. The posterior oblique portion, which spreads posteriorly over the medial tibial flare and incorporates the sheath of the semimembranosus tendon, tightens in extension. The anterior portion of the ligament complex, which extends anteriorly along the medial tibial flare, tightens in flexion and loosens in extension.
97. The knee is loose medially in extension after medial collateral ligament release. Fig. 98. The medial side also is loose in flexion. 58 Fig. 99. Compensatory release of the lateral collateralligament makes room for a larger tibial spacer especially in extension, but has some effect through the entire flexion arc. This release is done with a knife, releasing the lateral collateral ligament directly from the bone, but leaving it attached to the surrounding dense fibrous capsule, and to the popliteus tendon.
