42-year-old recreational skier. Chronic “deep front-of-knee pain.” Failed injections, failed PT. Told to wait for a total knee replacement.
Stairs were becoming a negotiation. Downhill skiing was disappearing from his life.
But only one compartment was failing.
→ Decision:
Careful evaluation confirmed isolated patellofemoral osteoarthritis with preserved tibiofemoral compartments which is a classic pattern where partial knee replacement may outperform total knee replacement in restoring more natural mechanics.
→ Outcome:
Patellofemoral arthroplasty restored smooth kneecap tracking and eliminated the “grinding pain” that had dominated every descent. Recovery was faster than expected, with early return to low-impact sport.
→ Lesson:
A total knee replacement is not always the “next step.”
In isolated disease, replacing everything can be overtreatment. Preserving healthy cartilage preserves function.
Patellofemoral arthroplasty is a surgical treatment for osteoarthritis. The knee joint is resurfaced with metal and plastic prosthetics.
