OSTEO-CHONDRITIS DISSECANS This is an unusual condition that develops in the last few years of growth, and is thought to occur because a small segment of the joint surface loses its blood supply long enough, or repeatedly enough, to become separated from the main body of the bone. The joint surface (articular cartilage) remains intact for a few months to several years, but when it splits around the margins of the lesion, the fragment of bone and articular cartilage separates and becomes an osteo-chondral loose body. This may click and cause discomfort and/or swelling. It may also dislodge and get jammed between the bones causing episodes of locking. The treatment is either to replace the fragment back in the crater it came from, and try to get it to heal, or if it is thought that is not going to succeed, or has already failed, then to just remove the loose body. That still leaves the question of the crater. If it is quite small, no further treatment may be necessary. If, on the other hand, the remaining crater is large enough to cause ongoing symptoms, or if it is lie that early arthritis will result, then it is desirable to find another way of trying to heal the defect. The most popular technique these days is to take some of the healthy articular cartilage from the joint, culture it in the lab for about 6 weeks, and then do what is called an Autologous Chondrocyte Impantation (ACI). If, as is usually the case these days, the graft comes on a collagen patch (matrix), then it is called Matrix Autologous Chondrocyte Impantation (MACI).
