Treatment Overview

FocusDetails
Non-Surgical CareActivity modification and low-impact exercise, Physical therapy for strength and mobility, Weight management to reduce joint load, Bracing or assistive devices
MedicationsNSAIDs for pain and inflammation, Acetaminophen for pain relief, Topical anti-inflammatory medications
InjectionsCorticosteroid injections for flares, Hyaluronic acid injections in selected cases
Surgical OptionsArthroscopy for mechanical symptoms in select cases, Osteotomy for alignment correction, Partial or total knee replacement for advanced disease

Self-Care and Recovery
