Osteochondritis is defined as a condition in which a portion of the bone along with an overlying section of cartilage gradually separates from the remaining bone and may eventually detach completely. This condition is painful and primarily affects males aged 15 to 20 years, occurring most frequently on the lateral aspect of the medial femoral condyle.
Osteochondritis dissecans can be classified into four stages:
- 1_ Stage : Presence of bone edema in the affected area.
- 2_ Stage: Bone edema persists with partial separation of the affected segment from the surrounding healthy bone.
- 3_ Stage: The affected segment completely detaches from the healthy bone.
- 4_ Stage: The detached segment is loose within the joint.
Etiology
Although the precise factors causing osteochondritis are not fully understood, the following are considered contributing factors:
- Reduced blood supply to the affected area.
- Trauma to the knee, particularly if repetitive.
- Overuse of the knee and surrounding structures.
Clinical Symptoms
Patients with osteochondritis commonly present with:
- Pain that worsens with physical activity.
- Swelling in the affected region.
- Limited range of motion of the knee.
- Weakness in knee extension.
Management of Osteochondritis
The appropriate management of osteochondritis is determined based on the stage of the condition, which is assessed through imaging, particularly magnetic resonance imaging (MRI). In general, the treatment options for osteochondritis include:
- Rest to minimize stress on the affected joint.
- Immobilization of the joint to allow healing of the bone and cartilage.
- Weight-bearing with crutches for a specified period, depending on the severity of the lesion.
- Physiotherapy program focused on stretching and strengthening
- Pharmacological therapy
- Surgical intervention, primarily performed arthroscopically, to achieve optimal outcomes while minimizing recovery time.
