Patellofemoral arthroplasty: expert opinion

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Isolated patellofemoral osteoarthritis (PFOA) is a frequent cause of anterior knee pain in individuals over 40.
• Patellofemoral arthroplasty (PFA) is a surgical option for PFOA when conservative management fails.

Purpose of the Study:

• To review the indications and surgical techniques for patellofemoral arthroplasty.
• To highlight the importance of patient selection and surgical expertise in PFA outcomes.

Main Methods:

• Review of current literature on patellofemoral arthroplasty.
• Discussion of surgical pearls and pitfalls.

Main Results:

• Advances in implant design and surgical techniques have improved functional and patient-reported outcomes.
• Appropriate patient selection is critical for successful PFA.

Conclusions:

• Patellofemoral arthroplasty is a viable option for select patients with isolated patellofemoral osteoarthritis.
• Optimizing implant design, surgical technique, and patient selection are key to successful outcomes.
