Patellofemoral Cartilage Repair

Area of Science:

• Orthopedics
• Regenerative Medicine
• Sports Medicine

Background:

• Cartilage defects in the patellofemoral joint (PFJ) are common and can lead to pain and dysfunction.
• Current treatments aim to delay or avoid arthroplasty and improve symptoms in young patients.

Purpose of the Study:

• To review established and novel cartilage repair techniques for PFJ defects.
• To present an algorithm for managing PFJ cartilage defects based on anatomical considerations.

Main Methods:

• Review of current literature on PFJ cartilage repair.
• Analysis of outcomes for various surgical techniques.

Main Results:

• Autologous chondrocyte implantation is effective for chondral lesions; osteochondral allografts for osteochondral defects.
• Tibial tubercle osteotomy can improve outcomes in cases of patellar malalignment.
• Particulated cartilage and bone marrow aspirate concentrate are emerging treatments.

Conclusions:

• Careful patient selection, surgical technique, and addressing concomitant abnormalities are crucial for successful PFJ cartilage repair.
• Further comparative studies and investigation of new techniques are necessary.
