Chondral injuries

Chondral injures are present in up to 10 to 12% of all individuals. When symptomatic, chondral lesions manifest in knee pain, swelling, and loss of function. Cartilage loss may be partial or complete, and it may affect one or multiple locations. The natural history of untreated lesions most likely results in increased disability and progression of cartilage loss. Lesions are classified according to location, depth, and size. Nonsurgical treatment modalities include oral medications, injections, bracing, or physical therapy. Surgical treatment ranges from arthroscopic debridement to implantation of autologous chondrocytes beneath a periosteal patch covering the lesion. The patient's symptoms, age, activity level, and lesion characteristics must be considered and matched with a suitable procedure.
