Varus Deformityp-knee-ankle angle) of less than 180° and varying degrees of contracture of medial soft-tissue structures, laxity of the lateral soft-tissue structures, flexion deformity and medial bone erosion at the knee joint. Medial osteophytes cause tethering and functional shortening of the medial soft-tissue

Flexion Deformityion of flexion in response to the pain and increased intra-articular pressure. Posterior femoral and tibial osteophytes along with those in the intercondylar notch in OA may enhance the deformity by tenting the posterior capsule or blocking full extension. This, in the long run, becomes a fixed flex

Rotational Deformity most of these landmarks and reference axes have been derived from normal unaffected knees. In knees with arthritis, these landmarks and axes may get distorted due to significant cartilage wear, bone loss, soft-tissue contracture and additional extra-articular bony deformities frequently associated

DOTE

Extra-Articular Deformitye achieved with appropriate bone cuts and soft-tissue releases. However, TKA becomes technically challenging when knee arthritis is associated with an extra-articular deformity (EAD) of either the femur or the tibia. Such deformities are commonly caused secondary to trauma (malunion or non-union), p

The Unstable Kneeateral side (in varus deformity) or medial side (in valgus deformity) shows excessive laxity with or without an associated posterior laxity (in hyperextension deformity). However, rarely, an arthritic knee undergoing TKA may also show multiplanar or global laxity where there is significant medial, l

Osteotomies in Total Knee Arthroplastyof an osteotomy. An osteotomy in primary TKA is usually indicated in rigid or severe deformities to facilitate soft-tissue balance and deformity correction, to concomitantly correct an extra-articular deformity or rarely to facilitate exposure of the joint. Frequently, in varus arthritic knees under
