Some symptoms of late stages of osteochondritis dissecans are found with other diseases like rheumatoid disease of children and meniscal ruptures. However, the disease can be confirmed by X-rays, computed tomography (CT) or magnetic resonance imaging (MRI) scans. Non-surgical treatment is successful in 50% of the cases. If in late stages the lesion is unstable and the cartilage is damaged, surgical intervention is an option as the ability for articular cartilage to heal is limited. When possible, non-operative forms of management such as protected reduced or non-weight bearing and immobilization are used. Surgical treatment includes arthroscopic drilling of intact lesions, securing of cartilage flap lesions with pins or screws, drilling and replacement of cartilage plugs, stem cell transplantation, and in very difficult situation in adults joint replacement. After surgery rehabilitation is usually a two-stage process of unloading and physical therapy. Most rehabilitation programs combine efforts to protect the joint with muscle strengthening and range of motion. During an immobilization period, isometric exercises, such as straight leg raises, are commonly used to restore muscle loss without disturbing the cartilage of the affected joint. Once the immobilization period has ended, physical therapy involves continuous passive motion (CPM) and/or low impact activities, such as walking or swimming. OCD occurs in 15 to 30 people per 100,000 in the general population each year. Although rare, it is an important cause of joint pain in physically active children and adolescents.
However, some physicians have preferred to use undifferentiated pluripotential cells, such as periosteal cells and bone marrow stem cells, as opposed to chondrocytes. These too have demonstrated the ability to regenerate both the cartilage and the underlying subchondral bone.Similar to OATS, arthroscopic articular cartilage paste grafting is a surgical procedure offering cost-effective, long-lasting results for stage IV lesions. A bone and cartilage paste derived from crushed plugs of the non-weight-bearing intercondylar notch can achieve pain relief, repair damaged tissue, and restore function. Unstable lesions
Some methods of fixation for unstable lesions include countersunk compression screws and Herbert screws or pins made of stainless steel or materials that can be absorbed by the body. If loose bodies are found, they are removed. Although each case is unique and treatment is chosen on an individual basis, ACI is generally performed on large defects in skeletally mature people. Rehabilitation
Continuous passive motion (CPM) has been used to improve healing of the articular surface during the postoperative period for people with full-thickness lesions. It has been shown to promote articular cartilage healing for small (< 3 mm in diameter) lesions in rabbits. Similarly, Rodrigo and Steadman reported that CPM for six hours per day for eight weeks produced an improved clinical outcome in humans.A rehabilitation program often involves protection of the compromised articular surface and underlying subchondral bone combined with maintenance of strength and range of motion. Post-operative analgesics, namely a mix of opioids and NSAIDs, are usually required to control pain, inflammation and swelling.
