A
Posterior cruciate ligament, then pes anserinus, then deep MCL
B
Osteophytes, then deep MCL, then posteromedial corner, then superficial MCL
C
Superficial MCL, then ACL, then deep MCL
D
Popliteus tendon, then IT band, then deep MCL
Explanation:Correct Option: B. The standard sequential medial release for a fixed varus knee begins with complete osteophyte removal, followed by release of the deep medial collateral ligament (MCL). If tightness persists, the posteromedial corner and capsule are released. The final step for severe deformity is the release or 'pie-crusting' of the superficial MCL.
