Primary Total Knee Arthroplasty in Patients With Severe Varus Deformity

Lateral Soft Tissue Laxity Increases but Medial Laxity Does Not Contract With Varus Deformity in Total Knee Arthroplasty

“…tissue would result in the use of a thicker insert that may cause elevation of the joint line [25,27], and the looser soft tissue may create postoperative instability [12,20]. Some surgeon may consider allowing slight varus postoperative alignment in the safe zone, as described by Fang et al [5] (2.4°-7.2°valgus in tibiofemoral angle).…”

Postoperative Lateral Ligamentous Laxity Diminishes with Time After TKA in the Varus Knee

With the latter strategy, there is a possibility of residual lateral ligamentous laxity after surgery.…”

Soft Tissue Balance in Total Knee Arthroplasty

“…Although severe intra-operative varus deformity needs substantial soft tissue release on the medial side during TKA, the ideal amount of medial release is still controversial; two strategies exist for soft tissue balancing in the varus knee. Some surgeons believe it is best to create equal medial and lateral gaps even in severely deformed knees [2,100,101]. Others accept some degree of lateral laxity is permissible, as long as proper alignment is maintained, based on evidence showing post-operative diminishment with time of lateral laxity after TKA [102,103].…”
