Restricted hip flexion and internal rotation bilaterally, more pronounced on the left. Pattern is consistent with anterior hip capsule tightness combined with weak posterior hip musculature. The 19% L/R asymmetry indicates a dominant compensation strategy — the right hip is carrying load the left hip isn't tolerating. This asymmetry is a primary driver of the reported lower back tightness: the lumbar spine is extending to compensate for restricted hip flexion during squat depth.

Severely limited dorsiflexion range. At 44/100, this is the most restricted joint in the assessment and likely the proximal driver of the knee and hip findings. Restricted ankle dorsiflexion prevents the tibia from translating forward over the foot during squat descent — the kinetic chain compensates by collapsing the knee medially and increasing hip flexion demand, creating a cascade of dysfunction up the chain.

Knee scores in the moderate-concern range, with patellofemoral tracking dysfunction most likely given the client's reported anterior knee discomfort during squats. The left knee scores 15% lower than the right, correlating with the left hip asymmetry above — inadequate hip stabilization is creating increased valgus stress at the left knee. This is a downstream consequence of the ankle and hip restrictions, not a primary knee pathology.
