Article Synopsis
- - The study investigated whether adding platelet-rich plasma (PRP) during hip arthroscopy for femoroacetabular impingement (FAI) improves patient outcomes compared to a saline placebo.
- - Conducted on patients aged 16 to 50 years, the trial randomly assigned 113 participants to receive either PRP or placebo before surgery, assessing their recovery using the International Hip Outcome Tool at various follow-up points.
- - Results showed both groups had improved hip scores after 2 years, but there was no significant difference in their recovery, indicating that PRP may not provide additional benefits for FAI surgery.
Despite remaining a controversial diagnosis, piriformis syndrome continues to affect patients' quality of life with pain, sitting discomfort, and exercise intolerance. Open sciatic neurolysis has been noted by the senior author to often only bring temporary relief of the symptoms, with the recurrence presumably due to postoperative scar tissue. Minimally invasive techniques used to decompress the nerve have met with mixed results.

Epidemiological figures of the prevalence are unknown, but are estimated to be about 12.2% to 27%.

Methods: Three groups were evaluated: in group 1 both hips were treated simultaneously, in group 2 both hips were treated in a staged fashion, and in group 3 a single hip was addressed. The outcome measures were anesthesia and surgical times; time in the hospital; visual analog scale score for pain on postoperative days 1, 3, 7, and 30; analgesic use; and time until the patient could bike, drive, perform office work, perform gym activities, run, and return to play.
