Insights
Arthroscopic hip remplissage using iliotibial band allograft successfully improved patient outcomes for hip instability due to cam over-resection. This salvage procedure offers significant benefits when primary surgery is compromised.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Hip Arthroscopy
Background:
- Hip instability can result from cam over-resection during hip arthroscopy.
- Salvage procedures are necessary when initial treatments lead to complications.
Purpose of the Study:
- To evaluate the outcomes of arthroscopic hip remplissage with folded iliotibial band allograft.
- To assess this technique as a treatment for hip instability following cam over-resection.
Main Methods:
- Prospective evaluation of 13 patients undergoing arthroscopic hip remplissage.
- Comparison of pre- and postoperative outcome scores including SF12, WOMAC, mHHS, and HOS.
- Assessment of Tegner Activity Scale and patient satisfaction post-surgery.
Main Results:
- Significant improvements in SF12 PCS, mHHS, WOMAC, HOS ADL, and HOS Sport scores were observed (P < .05).
- 12 of 13 patients showed improved outcomes, with one requiring total hip arthroplasty.
- Median patient satisfaction was 7/10, and median Tegner score was 2.9.
Conclusions:
- Arthroscopic hip remplissage is a successful salvage treatment for hip instability post-cam over-resection.
- Avoiding over-resection during primary hip arthroscopy is crucial for optimal patient outcomes.
Purpose:
To evaluate outcomes of arthroscopic hip remplissage with folded iliotibial band allograft to treat cam over-resection.
Methods:
Patients who underwent arthroscopic iliotibial band hip remplissage from May 2013 to April 2018 were prospectively evaluated. Pre- and postoperative patient-reported outcome scores were compared and included the 12-Item Short Form Survey (SF12) Physical Health Composite Score (PCS), SF12 Mental Health Composite Score (MCS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), modified Harris Hip Score (mHHS), and Hip Outcome Score (HOS) (Activities of Daily Living [ADL] and Sport). Postoperative Tegner Activity Scale and patient satisfaction (1-10) were also evaluated.
Results:
Thirteen patients (2 men, 11 women) with an average age of 39.8 ± 9 years underwent arthroscopic hip remplissage with minimum 2-year and mean 3.1-year follow-up (range, 2.1-4.1 years). One hundred percent follow-up was achieved. The average number of previous surgeries was 1.38 (range, 1-3). One patient underwent total hip arthroplasty 2 years after remplissage. All 12 patients who did not undergo total hip arthroplasty had improved patient-reported outcomes after remplissage (mean scores: SF12 PCS 36 vs 42, P = .02; SF12 MCS 45 vs 51, P = .14; mHHS 45 vs 66, P < .001; minimal clinically important difference [MCID] 83%; WOMAC 42 vs 28, P < .001; HOS ADL 52 vs 69, P = .003; MCID, 67%; HOS Sport 27 vs 46, P = .015; MCID, 67%). All improvements met statistical significance, besides the SF12 MCS. Median postoperative Tegner score was 2.9. Median postoperative patient satisfaction was 7 out of 10 (range, 5-10).
Conclusions:
Arthroscopic hip remplissage is a successful salvage treatment option for hip instability caused by previous cam over-resection. Care must be taken during primary surgery not to over-resect the cam as patient-reported outcomes after remplissage are inferior to those undergoing primary hip arthroscopy.
Level Of Evidence:
Level IV, case series.
