Final answer:
Releasing the IT band during a Total Knee Arthroplasty (TKA) affects coronal balance by adjusting lateral tension and can correct a varus deformity. However, overcorrection must be avoided to prevent a valgus deformity.
Step-by-step explanation:
The question 'Release the IT band will have what effect on the coronal balancing in a TKA?' addresses the impact of iliotibial (IT) band release on the balancing of the knee during a Total Knee Arthroplasty (TKA). It is important to achieve proper coronal balance in TKA to prevent uneven wear on the implant, reduce pain, and improve function. Releasing the IT band can adjust the lateral tension and help correct a varus deformity of the knee, where the knee tends to bend outward. However, this must be done carefully to prevent overcorrection leading to a valgus deformity, where the knee bends inward.
