Which cartilage is affected?
Articular cartilage covers the ends of bones and allows them to glide smoothly. A localized lesion, sometimes traumatic, is distinct from the more diffuse involvement of osteoarthritis. It may be associated with a meniscal or ligamentous lesion.
Characterizing the lesion
The assessment compares symptoms, examination, and imaging. The location, the affected surface area, the depth, and the condition of the underlying bone guide the discussion, along with the stability and alignment of the knee.
Adapting the treatment
Treatment may begin with activity modifications and rehabilitation. For certain troublesome focal lesions, reconstructive surgery may be considered: bone marrow stimulation or osteochondral grafting, in particular. These techniques have different indications and are not suitable for all types of osteoarthritis.
Protecting the repair
Weight-bearing restrictions and rehabilitation depend on the specific movement. Recovery can be lengthy; cartilage that is exactly identical to the original cartilage is not guaranteed.
Your questions.
Should I operate on any lesion visible on imaging?+
No. The severity of the discomfort, the lesion, and the overall context of the knee must be assessed together.
