Summary
Surgical outcomes for adolescent patellar osteochondral fractures varied. Patients undergoing loose body removal with microfracture reported better knee function and quality of life compared to those with fracture fixation.
Area of Science:
- Orthopedic surgery
- Pediatric orthopedics
- Sports medicine
Background:
- Adolescent patellar dislocations can lead to osteochondral fractures.
- Surgical management is considered for these injuries.
Purpose of the Study:
- To review surgical outcomes of adolescent patients with patellar osteochondral fractures after dislocation.
- To compare fixation versus non-fixation (excision and microfracture) treatment strategies.
Main Methods:
- Retrospective case series of nine adolescent patients.
- Surgical interventions included arthroscopic fixation (screws/pins) or loose body excision with microfracture.
- Outcomes assessed using International Knee Documentation Committee (IKDC) and Knee injury and Osteoarthritis Outcome Score (KOOS).
Main Results:
- Average patient age was 14.6 years, with a mean follow-up of 30.2 months.
- Five patients had loose body excision/microfracture; four had fixation.
- Non-fixation group had smaller average defect size (1.2 cm²) and higher IKDC (76.1) and KOOS scores compared to the fixation group (3.2 cm², IKDC 63.9).
Conclusions:
- This study is the first to examine surgical outcomes for adolescent patellar osteochondral fractures post-dislocation.
- Patients treated with non-fixation (excision/microfracture) showed better subjective outcomes.
- Observed differences may be influenced by initial injury severity, with fixation potentially reserved for larger, more severe fractures.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
