Patient presents with progressive medial arch pain and swelling in the right foot, exacerbated by weight-bearing activities. Reports a gradual loss of arch height and increasing difficulty with single-limb heel rise. No history of acute trauma. Pain is localized along the course of the posterior tibial tendon.

Clinical Examination Findings

Single-limb heel rise test is weak or impossible on the right side. Passive range of motion of the subtalar joint is restricted; forefoot abduction is present. Neurovascular status is intact.

Treatment Protocol

Conservative management initiated including rest, ice, and non-steroidal anti-inflammatory drugs (NSAIDs). Prescription for custom orthotics or medial arch support provided. Physical therapy referral for strengthening of the posterior tibial tendon and intrinsic foot muscles. Immobilization with a walking boot or ankle-foot orthosis (AFO) considered if symptoms persist.
