Postoperative Gait Parameters in Hip Resurfacing Compared to Total Hip Arthroplasty: A Systematic Review
Authors: Parsa A, George T, Bruning R, Padilla P, Schinsky MF, Domb BG
Background:
Hip resurfacing (HR) is increasingly considered for younger, active patients as an alternative to total hip arthroplasty (THA), with presumed advantages in gait mechanics and joint preservation.
Methods:
A systematic review following PRISMA guidelines analyzed 8 studies involving 206 patients comparing postoperative gait outcomes between HR and THA.
Key Findings:
- HR patients consistently demonstrated superior walking speed, stride length, and uphill walking ability relative to THA patients.
- HR was also associated with longer stance times and improved peak hip extension moments in several studies.
- On level surfaces, gait parameters were comparable between HR and THA groups.
Conclusion:
HR may offer functional advantages over THA, particularly for patients requiring higher mobility and endurance, though evidence remains limited. Both procedures yield effective clinical outcomes.
What Does This Mean for Providers?
When counseling active or younger patients, consider HR as a potential option that may enhance postoperative gait performance and endurance, especially for activities involving inclines. Decision-making should incorporate patient activity goals, anatomy, and long-term joint preservation considerations.
