Background: Revision hip arthroscopy is increasingly common and often addresses acetabular labrum pathology. There is a lack of consensus on indications or outcomes of revision labral repair versus reconstruction. Purpose: To report clinical outcomes of labral reconstruction during revision hip arthroscopy at minimum 2-year follow-up as compared with pair-matched labral repair during revision hip arthroscopy (control group) and to suggest a decision-making algorithm for labral treatment in revision hip arthroscopy. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent revision hip arthroscopy with labral reconstruction were matched 1:2 with patients who underwent revision arthroscopic labral repair. Patients were matched according to age, sex, and body mass index. Outcome scores, including the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score, Hip Outcome Score–Sport-Specific Subscale, and a visual analog scale for pain, were collected preoperatively and at minimum 2-year follow-up. At latest follow-up, patient satisfaction on a 0-10 scale and the abbreviated International Hip Outcome Tool (iHOT-12) were collected. Complications, subsequent arthroscopies, and conversion to total hip arthroplasty were collected as well. Results: A total of 15 revision labral reconstructions were pair matched to 30 revision labral repairs. The reconstructions had fewer isolated Seldes type I detachments ( P = .008) and lower postoperative lateral center-edge angle, but there were otherwise no significant differences in demographics, radiographics, intraoperative findings, or procedures. Both groups demonstrated significant improvements in all outcomes and visual analog scale at minimum 2-year follow-up. The revision repairs trended toward better preoperative scores: mHHS (mean ± SD: 59.3 ± 16.5 vs 54.2 ± 16.0), Non-Arthritic Hip Score (61.0 ± 16.7 vs 51.2 ± 17.6), Hip Outcome Score–Sport-Specific Subscale (39.6 ± 25.1 vs 30.5 ± 22.1), and visual analog scale (5.8 ± 1.8 vs 6.2 ± 2.2). At follow-up, the revision repair group had significantly higher mHHS (84.1 ± 14.8 vs 72.0 ± 18.3, P = .043) and iHOT-12 (72.2 ± 23.3 vs 49.0 ± 27.6, P = .023) scores than the reconstruction group. The magnitudes of pre- to postoperative improvement between the groups were comparable. The groups also had comparable rates of complications: 1 case of numbness in each group ( P > .999), subsequent arthroscopies (repair: n = 2, 6.5%; revision: n = 3, 20%; P = .150), and conversion to total hip arthroplasty (1 patient in each group, P > .999). Conclusion: Labral reconstruction safely and effectively treats irreparable labra in revision hip arthroscopy. However, labral repair is another treatment option for reparable labra, yielding similar magnitude of improvement. A proposed algorithm may assist in surgical decision making to achieve optimal outcomes based on the condition and history of each patient’s acetabular labrum.

Abstract While dislocation is a leading cause of total hip replacement failure, empirical observations far outnumber systematic laboratory examinations of this phenomenon. A previously validated three-dimensional, non-linear, contact finite element model was used to study how surgical placement affects dislocation propensity. The computational model employed a widely used 22mm modular system, and examined range of motion prior to impingement as well as peak moment developed to resist dislocation under a typical leg-crossing maneuver. Results were compared to a previous study of an otherwise similar 26mm modular head system, using the same formulation. Similar trends occurred. Increasing tilt and/or anteversion increased both the range of motion and the peak resisting moment, while apparent stiffness seemed to be unaffected. Further, impingement range of motion was independent of head size, but peak resisting moment was nearly 25% less for the 22mm head sizes.

Three-dimensional (3D) printed titanium orthopaedic implants have recently revolutionized the treatment of massive bone defects in the pelvis, and we are on the verge of a change from conventional to 3D printed manufacture for the mass production of millions of off-the-shelf (non-personalized) implants. The process of 3D printing has many adjustable variables, which taken together with the possible variation in designs that can be printed, has created even more possible variables in the final product that must be understood if we are to predict the performance and safety of 3D printed implants. We critically reviewed the clinical use of 3D printing in orthopaedics, focusing on cementless acetabular components used in total hip arthroplasty. We defined the clinical and engineering rationale of 3D printed acetabular cups, summarized the key variables involved in the manufacturing process that influence the properties of the final parts, together with the main limitations of this technology, and created a classification according to end-use application to help explain the controversial and topical issues. Whilst early clinical outcomes related to 3D printed cups have been promising, in-depth robust investigations are needed, partly because regulatory approval systems have not fully adapted to the change in technology. Analysis of both pristine and retrieved cups, together with long-term clinical outcomes, will help the transition to 3D printing to be managed safely.
