Medial and lateral soft-tissue releases to correct varus and valgus
deformities in primary total knee arthroplasty are achieved by sequential
release of contracted soft-tissue constraints or, occasionally, advancement of
elongated
ligaments1-3.
In primary total knee arthroplasty, soft-tissue constraints are typically
well-defined anatomical structures, whereas, in revision total knee
arthroplasty, the soft-tissue constraints may be thickened and scarred,
attenuated, or absent. Soft-tissue balance in revision total knee arthroplasty
is achieved by a combination of soft-tissue releases and variation in the bone
resection level, implant position, and implant
size4.
