Key result
A review of 5 studies suggests corrective surgery for femoroacetabular impingement improves biomechanical hip function, but its impact on the progression of degenerative changes remains unproven.
Why the study?
Does corrective surgery for FAI improve biomechanical hip function and prevent osteoarthritis progression?
Does corrective surgery for FAI improve biomechanical hip function and prevent osteoarthritis progression?
While FAI surgery improves hip biomechanics, there is currently insufficient evidence to prove it prevents or delays the progression of hip osteoarthritis.
Answers are grounded in this paper and cite their sources.
FAI surgery should not yet alter OA prevention practice; leaves open whether biomechanical gains slow degenerative progression.
Femoroacetabular impingement (FAI) has been identified as a potential cause of hip osteoarthritis. The goal of FAI surgery is to relieve pain, and hopefully delay or prevent osteoarthritis of the hip. Several studies have now demonstrated favorable clinical outcomes after arthroscopic and open surgical correction of symptomatic FAI. The concept is restoration of normal hip anatomy may result in improved biomechanical function and kinematics of the hip, which may prevent or delay the progression of osteoarthritis. Although many clinical studies demonstrate restoration of "normal" anatomy, there are few studies evaluating improvement of biomechanics and function. To date, only 5 studies have been published in the English literature that study biomechanics and/or kinematics of the hip both preoperatively and postoperatively. At this point in the understanding of FAI, critical analysis of the literature suggests that FAI surgery can improve several parameters of biomechanical hip function. However, the impact of these improved biomechanics on the natural history and progression of degenerative changes in patients that are treated for symptomatic FAI has not been demonstrated.

Sampson et al. (2015) conducted a review in Femoroacetabular impingement (FAI). Corrective surgery was evaluated on Biomechanical hip function and kinematics. A review of 5 studies suggests corrective surgery for femoroacetabular impingement improves biomechanical hip function, but its impact on the progression of degenerative changes remains unproven.
