Bones of the Flexed Knee, Medial View

Description

Viewed from the medial aspect with the knee in flexion, the distal femur sits superior to the proximal tibia, with the medial femoral condyle apposed to the weight-bearing surface of the medial tibial condyle (medial tibial plateau). Anteriorly, the patella lies in front of the distal femur, its articular surface oriented posteriorly toward the femoral trochlea even though the medial condylar surfaces dominate this perspective. The tibial shaft extends distally and slightly anterior to the femoral shaft in flexion, clarifying how the femoral condyles roll and glide on the tibial plateau during knee motion. Medial osseous relationships matter because they frame the compartment most commonly affected in varus-aligned knee osteoarthritis, where cartilage loss concentrates on the medial femoral condyle and medial tibial plateau. Flexion changes contact mechanics, shifting the femorotibial contact area posteriorly on the condyles, a point that explains why posterior horn medial meniscus tears and posterior medial cartilage wear are frequent pain generators in deep flexion activities. Coronal plane landmarks on the medial side also guide tibial component rotation and alignment targets in unicompartmental or total knee arthroplasty. Orthopedic teaching sets often need a clean medial view to pair with menisci and ligament overlays, and this angle supports modules on tibiofemoral kinematics, compartment loading, and cartilage-bearing surfaces in gross anatomy and kinesiology courses. It also suits surgical atlases and patient-education materials discussing medial compartment degeneration, osteotomy planning, and arthroplasty surface replacement.
