Autologous chondrocyte implantation (ACI, ATC code M09AX02 ()) is a biomedical treatment that repairs damages in articular cartilage.ACI provides pain relief while at the same time slowing down the progression or considerably delaying partial or total joint replacement (knee replacement) surgery.
Ankle replacement, or ankle arthroplasty, is a surgical procedure to replace the damaged articular surfaces of the human ankle joint with prosthetic components. This procedure is becoming the treatment of choice for patients requiring arthroplasty, replacing the conventional use of arthrodesis , i.e. fusion of the bones.
ACI articular cartilage repair procedures take place in three stages. First, cartilage cells are extracted arthroscopically from the patient's healthy articular cartilage that is located in a non load-bearing area of either the intercondylar notch or the superior ridge of the femoral condyles.
Marrow-nucleated cells are used every day in regenerative orthopedics. The knee microfracture surgery technique relies on the release of these cells into a cartilage lesion to initiate fibrocartilage repair in osteochondral defects. [13] In addition, this cell population has also been shown to assist in the repair of non-union fractures. [14]
A portion of the leg removed; the ankle joint is then turned 180 degrees and is reattached to the thigh. They are held together by plates and screws until they have healed naturally. The surgery can take anywhere from 6 to 10 hours, with a day or two in intensive care. [7] The leg is kept in a cast for 6 to 12 weeks.
The International Cartilage Repair Society has set up an arthroscopic grading system by which cartilage defects can be ranked: grade 0: (normal) healthy cartilage; grade 1: the cartilage has a soft spot, blisters, or superficial wear; grade 2: minor tears of less than one-half the thickness of the cartilage layer
Articular cartilage stem cell paste grafting was initially described by Kevin R. Stone M.D., a San Francisco-based orthopedic surgeon, in 1997 .The technique was devised in response to reports that many of the contemporary cartilage restoration procedures lead to the development of fibrocartilage, not true hyaline articular cartilage.
The Broström operation (or Broström-Gould technique) is a repair of ligaments on lateral ankle. It is designed to address ankle instability. More importantly, it is primarily used to repair the anterior talofibular ligament (ATFL) in the ankle. It is thought that the majority of patients regain most function in their ankles.
