Arthritis is one of the top diseases that plagues the aging population; with osteoarthritis being the main assailant. Although sometimes mild, this disease can quickly turn into a painful menace that inhibits daily activities.
One type of osteoarthritis that often leads to meniscal disruption, ligament instability, or limb deformity is unicompartmental arthritis. This subset of arthritis affects only one compartment of the joint, and it usually attacks the articular cartilage in the medial or lateral part of the tibiofemoral joint.
When unicompartmental arthritis hits the advanced stages and surgery becomes necessary, patients have to choose between unicompartmental knee arthroplasty (UKA) and total knee arthroplasty. UKA has recently become the preferred method due to its 10-year survival rate of 95%.
