A Physiotherapeutic Approach to a Rare Case of Windswept Deformity in a Male Adolescent

Primary hyperparathyroidism (PHPT) can lead to a rare condition in children and adolescents known as windswept deformity. This deformity involves one knee exhibiting an abnormal outward angulation (valgus deformity), while the other knee shows an abnormal inward angulation (varus deformity). This asymmetrical syndrome, resembling the effect of strong winds, gives the impression that the knees are being swept in opposite directions. Various factors, such as structural bone or joint defects, accidents, or underlying disorders, can contribute to the development of windswept deformity. PHPT, a common endocrine condition characterized by elevated levels of parathyroid hormone and blood calcium, is unusual in the pediatric and adolescent populations. It can result in complications like osteoporosis and bone abnormalities, with genu valgus (outward knee angulation) being an exceptionally rare symptom. This case discusses a 19-year-old male who underwent corrective surgery for genu valgus and presented with windswept deformity due to teenage hyperparathyroidism. The case study outlines the physiotherapeutic rehabilitation strategy, emphasizing treatments such as cryotherapy, patellar mobilization, and gait training. Tailored physical therapy rehabilitation plays a crucial role in the postoperative care of patients undergoing corrective osteotomies. The results indicated a significant improvement in muscle strength, an expansion of the range of motion (ROM), and a noticeable enhancement in the individual's functional autonomy following adherence to the postoperative physiotherapy (PT) plan.
