Total Knee Arthroplasty vs Uni Compartment Knee Arthroplasty in Management of Anteromedial Knee Osteoarthritis

Abstract

SUMMARY • Both UKA and TKA are good options in treatment of isolated anteromedial knee osteoarthritis. • ACL deficiency and central large lateral compartement ulcer are contraindications for UKA and operation should be shifted to TKA. • Never to prepare a uni case without a total knee backup set is present. • Intraoperative assessment for ACL and lateral compartment is a must before proceeding by a UKA. • Clinical and radiographic assessment is not enough to take the decision and proceeding for UKA. • Although UKA can reserve the bone stock of the knee joint and keep the native knee joint mechanics; the long term functional outcome and complication rate are the same after both UKA and TKA in this study population. • UKA has a better early functional outcome but this study couldn’t predict the durability of UKA. • As regard postoperative complications there is no a significant difference between UKA and TKA. • UKA needs more studies to know its durability.
