Cartilage restoration procedures in patellofemoral stabilization

Area of Science:

• Orthopedics
• Sports Medicine
• Regenerative Medicine

Background:

• Patellar instability and dislocation frequently lead to chondral injury in the patellofemoral joint.
• Symptoms include anterior knee pain, swelling, and mechanical issues, necessitating thorough clinical and imaging evaluation.
• Both soft tissue and bony factors contribute to patellar maltracking, complicating treatment.

Purpose of the Study:

• To review current treatments and therapies for managing patellofemoral chondral injuries.
• To explore interventions including cell-based therapies, orthobiologics, and osteochondral approaches.
• To guide surgical decision-making based on defect characteristics and patient factors.

Main Methods:

• Comprehensive literature review of interventions for patellofemoral chondral injuries.
• Analysis of techniques based on defect size, location, patient age, and activity level.
• Evaluation of cell-based, orthobiologic, and osteochondral-based approaches.

Main Results:

• Smaller defects in low-demand patients may be treated with chondroplasty or microfracture.
• Larger, full-thickness defects without subchondral bone involvement are often managed with cell-based therapies.
• Full-thickness defects with osteochondral involvement are best addressed with osteochondral grafts.

Conclusions:

• Management of patellofemoral chondral injuries requires tailored approaches based on injury specifics.
• Cell-based therapies are common for larger defects, while osteochondral approaches suit those with bone involvement.
• Understanding indications, risks, and benefits of various techniques is crucial for orthopedic surgeons.
