Area of Science:

  • Orthopedic surgery
  • Biomedical engineering
  • Rheumatology

Background:

  • Patellofemoral arthritis causes anterior knee pain and limits daily activities.
  • It can occur in isolation or with other forms of knee osteoarthritis.
  • Patellofemoral arthroplasty is an increasingly popular treatment, particularly with novel implant designs.

Observation:

  • A 37-year-old female with a below-knee amputation and isolated patellofemoral arthritis underwent inlay patellofemoral arthroplasty.
  • She had failed multiple conservative treatment options prior to surgery.
  • The patient was monitored for two years post-procedure.

Findings:

  • Immediate improvements in knee range of motion and pain reduction were reported.
  • Significant improvements were observed in multiple outcome measures, including IKDC, Lysholm, and KOOS scores.
  • Two-year follow-up demonstrated drastic functional recovery and pain relief.

Implications:

  • Inlay patellofemoral arthroplasty is a viable surgical solution for isolated patellofemoral arthritis.
  • This procedure yields successful outcomes even after conservative treatment failure.
  • It is a valuable option for patients with limited tibiofemoral arthritis.
