Chondromalacia in Lipedema: The Sarcopenic-Valgus Cascade That Keeps Getting Missed.

Knee pain in women with lipedema is frequently misattributed and undertreated. We outline a biomechanical and inflammatory cascade linking systemic adipose dysfunction, anabolic resistance, and thigh-predominant sarcopenia to dynamic knee valgus, plantar arch collapse, altered gait, patellofemoral malalignment, and ultimately chondromalacia patellae. We integrate synovial-adipose crosstalk and the high prevalence of generalized joint hypermobility as amplifiers of joint loading. This framework supports a practical, staged approach that couples symptom control with progressive, targeted strengthening and gait retraining. Rather than treating the knee in isolation, addressing the cascade may reduce pain and improve function.
