Articular cartilage – the soft white cartilage that covers the ends of the bones and helps joints to move smoothly – is vital to the structure and function of knee joints. It also helps to absorb the forces throughout the knee. Once damaged, cartilage is unable to repair itself and the joint cartilage gradually wears away.
Left untreated, this condition can develop into osteoarthritis (OA). It is not only painful, but can complicate the treatment of other medical conditions – particularly diabetes and heart disease – because it hinders the physical activity that is an important aspect of managing these conditions.
Although some conditions of articular cartilage can be treated non-operatively, surgical repair techniques are often used to help ensure patients reap the best possible outcome in the long run. To better understand, let’s take a closer look at the disease process of OA.
Surgical treatment options:
- Marrow stimulation. This technique involves arthroscopically removing the calcified cartilage layer from the bone and then creating several small holes in the plate. These holes allow the marrow contents to enter the joint, adhere to the exposed bone and eventually help repair tissue. This technique is generally reserved for smaller well-contained cartilage lesions. Newer techniques involve the augmentation of repair tissue using growth factors and protein to induce cartilage repair and a more hyaline-like (transparent and filled with collagen) tissue.
- Osteochondral (bone and cartilage) grafting. The most widely used technique is an autograft (tissue taken from the individual’s own body) transplantation. This technique is generally reserved for midsized lesions. Larger lesions can be treated with allograft (tissue taken from a cadaver) transplantation. This technique allows for grafting of cartilage lesions of unlimited size and potentially at multiple sites.
- Cell-based repair. Autologous cell implantation is a two-stage procedure in which a biopsy specimen of the joint cartilage is taken, cultured and ultimately re-implanted during a second procedure under a patch sutured around the cartilage defect.
- Fragmented cartilage implantation. Fragmented cartilage implantation involves the selective growth of cartilage cells with favorable characteristics. It involves arthroscopically harvesting healthy cartilage from a relatively non weight-bearing segment of the joint, dividing the cartilage, and then re-implanting into the defect. This technique eliminates the need for a biopsy and a second operation.
It’s important to understand that all cartilage lesions are not symptomatic and, likewise, all symptoms don’t necessarily some from cartilage lesions. If you are experiencing knee pain, it’s best to be evaluated by an expert who can set up a personalized treatment plan.
