A Case of “Windswept Deformity” in which Symptoms were Improved by Exercise Therapy Combined with Platelet-rich Plasma (PRP) Therapy

Abstract

Purpose: We report the beneficial results of conservative therapy in a case of bilateral knee osteoarthritis called “windswept deformity”.

Methods: The patient was a woman in her 70s with bilateral knee osteoarthritis presenting varus and valgus deformities on the left and right knees, respectively. We performed exercise therapy and activities of daily living guidance for 3 months. Subsequently, the patient was treated for knee osteoarthritis with exercise therapy in combination with platelet-rich plasma therapy, known to have a therapeutic effect in recent years. Treatment outcomes were assessed using the Knee injury and Osteoarthritis Outcome Score (KOOS), a patient-based evaluation.

Results: Both physical function and ability were found to improve following the treatment regimen. KOOS showed improvement, and the responder criteria of OMERACT-OARSI were also found to be effective.

Conclusion: The findings of this case report suggest the possibility of developing effective exercise therapy for knee osteoarthritis in the future.
