Comparison of 8-year knee osteoarthritis progression in 2 siblings: a case-based review.

ABSTRACT: Because the pathophysiology of knee osteoarthritis is poorly understood, optimal evidence-based clinical management is uncertain. Sibling comparison studies can help inform a clinical model to guide preventive care. We compared the 8-year clinical outcomes in 2 sisters with a family history of osteoarthritis, normal BMI, and absence of knee pain at baseline. Both patients had Kellgren-Lawrence grade 1 in the affected knee at the time of twisting knee injuries leading to osteoarthritis diagnoses at age 50 (patient 1) and 51 (patient 2). Patient 1 developed a chronic right knee effusion, and progressed to Kellgren-Lawrence grade 3 bilaterally by the time she had a right total knee replacement at age 58. Patient 2 had subchondral fractures of the right knee with transient effusion, which heal
