Selective Femoral Resurfacing for Bilateral Knee Osteonecrosis: A Bone‐Preserving Alternative to Total Knee Arthroplasty

IntroductionSymptomatic avascular necrosis of the knee in young patients represents a therapeutic challenge. We present two cases of patients with bilateral massive osteonecrosis and advanced femoral chondropathy treated with bilateral femoral resurfacing.ConclusionProsthetic resurfacing of the distal femur in symptomatic osteonecrosis may represent a bone-sparing technique for young patients, specifically targeting the pathological compartments. It allows for a rapid return to normal activity, reduces pain, and may delay the need for total knee replacement.
