Clinical & Coding Specifications

Clinical Context

A 58-year-old active patient presents to an outpatient orthopedic clinic with chronic knee pain and medial joint instability after a partial meniscectomy six weeks prior. The orthopedic surgeon determines that a prefabricated elastic knee orthosis with integrated joints can provide immediate medial-lateral support and symptom control while the patient undergoes progressive rehabilitation. The orthotist evaluates knee alignment, trims and molds the prefabricated device to the patient’s limb, and adjusts joint tension to optimize fit and function. The device is dispensed in the clinic; patient education on donning, doffing, skin checks, and wear schedule is provided. Follow-up occurs in 2–4 weeks for reassessment and potential further customization.
