Osteochondral Fracture Associated With Patellar Dislocation: Surgical Treatment

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Traumatology

Background:

• Patellar dislocations can involve osteochondral fractures of the patella or femur.
• These fractures often present with fragments that may require surgical intervention.

Purpose of the Study:

• To evaluate the surgical management of osteochondral fractures associated with first-time patellar dislocations.
• To assess the outcomes of prompt fragment fixation and medial patellofemoral ligament (MPFL) stabilization.

Main Methods:

• Arthrotomy for retrieval and fixation of osteochondral fragments using headless screws.
• Medial patellofemoral ligament (MPFL) repair or reconstruction (autograft preferred) for patellar stabilization.

Main Results:

• Prompt fixation restores articular surface congruity, preventing long-term issues like osteoarthritis.
• Surgical intervention led to good functional outcomes and return to sport for patients.

Conclusions:

• Surgical treatment is recommended for osteochondral fractures impacting joint congruity after the initial patellar dislocation episode.
• Concurrent MPFL repair or reconstruction, preferably reconstruction, is advised for optimal results.
