Arthroscopic femoral osteochondroplasty for cam-type femoroacetabular impingement: the trough technique. Femoral morphology in patients undergoing periacetabular osteotomy for classic or borderline acetabular dysplasia: are cam deformities common? J Arthroplast. 2018 26(8):2512–8.Īnderson LA, Erickson JA, Swann RP, McAlister IP, Anderson MB, Sierra RJ, et al. Acetabular labral reconstruction using the indirect head of the rectus femoris tendon significantly improves patient reported outcomes. 2009 91(5):589–94.Īmar E, Sampson TG, Sharfman ZT, Caplan A, Rippel N, Atzmon R, et al. Prevalence of associated deformities and hip pain in patients with cam-type femoroacetabular impingement. The utility of hip arthroscopy in the setting of acetabular dysplasia: a systematic review. In these instances, PAO surgery may be revisited when other causes for recurrent symptoms have been ruled out (i.e., adhesions, residual impingement, heterotopic ossification) and instability is deemed to be the most likely culprit. These patients require close monitoring during the first year of their postoperative rehabilitation as latent instability often presents with recurrent symptoms upon return to higher demand activities at the 6- to 12-month postoperative time point. However, in select cases of borderline hip dysplasia, hip arthroscopy may be utilized as a sole first-line treatment, particularly when the combined torsion and version index (COTAV) and Beighton laxity score (BLS) are low. For patients with frank hip dysplasia, the intra-articular work performed during hip arthroscopy is routinely followed by extra-articular realignment with a periacetabular osteotomy (PAO) and/or derotational femoral osteotomy (DFO). The authors posit that hip arthroscopy is an important part of the treatment algorithm for patients with hip dysplasia and can meaningfully address labral pathology, concomitant cam-type femoroacetabular impingement, acetabular subchondral cysts, capsular laxity, and ligamentum teres pathology. Thus, the utility of hip arthroscopy for patients with hip dysplasia came into question as surgeons attempted to refine their indications. Hip arthroscopy as a sole treatment strategy in patients with hip dysplasia has yielded variable results historically, including frank hip dislocations postoperatively and rapid degeneration leading to early osteoarthritis (OA) and total hip replacement (THR).
