Chondral knee injuries have different manifestations and presentation modes. The symptoms and treatments depend on the size thereof, the location, the functional demands, the presence of chondral loose bodies, the thickness of the lesion, the limb alignment, the evolution time and the accompanying lesions.
The classic treatment techniques like debridement, abrasion or microperforating allow for treating small to medium-sized injuries or lesions presenting little symptomology. However, restoration techniques, where an attempt is made to coat the defect with cartilaginous tissue, are used on advanced lesions. While the focus should be fully customized, the two techniques most frequently performed by Dr. Gelber differ depending on whether the injury is only of articular cartilage or, on the other hand, the injury also compromises the underlying bone layer (osteochondral injury).
