Abstract
Anterior knee pain is a common symptom in general orthopedic practice and is reported in 8% of women and 2% of men over the age of 55 years. The treatment of isolated patellofemoral arthritis is controversial. Many patients can be effectively managed conservatively. Analysis was done on 14 patients (17 knees) with symptomatic isolated patellofemoral osteoarthritis between 2001 and 2007. 3 patients had additional procedures like tibial tubercle osteotomy and lateral release, tibial tubercle osteotomy with medical plication and iliotibial band lengthening and lateral retinacular release. The operation should be viewed as a soft-tissue procedure involving resurfacing of the femoral trochlea and the articular surface of the patella. Proper balance of the extensor mechanism must be done at the time of surgery to ensure correct tracking of the patella which in turn results in the best outcome for the replacement.

We report the short-term results of patients with patellofemoral osteoarthritis who have been treated with a patellofemoral replacement
We studied the outcome of patellofemoral arthroplasty in 14 consecutive patients (17 knees) with isolated patellofemoral osteoarthritis treated between 2001 and 2007
Summary
Anterior knee pain is a common symptom in general orthopaedic practice and is reported in 8% of women and 2% of men over the age of 55 years. The treatment of isolated patellofemoral arthritis is controversial [1]. The etiology of the disease can be traumatic, secondary to malalignment, degenerative, idiopathic, or a combination of these. Many patients can be treated effectively with nonoperative means, including strengthening exercises, bracing, medications, and activity modifications. There are a group of patients with severe disease who are quite disabled and may require surgery. Surgical treatment may be necessary in patients with chronic patellar subluxation, osteochondritis dissecans
