Patients who suffer from chronic patellofemoral syndrome (PFPS), which causes pain in the front part of the knee, gain no extra benefit arthroscopic surgery.
In a randomized controlled trial, patients were divided into two groups. The first group was treated with knee arthroscopy and an eight-week home exercise program, and the second group was treated with the exercise program only.
After 9 months, both groups showed reduced pain and improvement in knee mobility. However, the improvements for patients treated with surgery and exercise were almost exactly the same as for the patients treated with exercise alone. A second follow up after two years showed the same results.
The average cost of treatment was more than $1,300 higher for patients who underwent both arthroscopy and exercise therapy.
