Ankem HK, Ouyang VW, Saks BR, Jimenez AE, Sabetian PW, Maldonado DR, Lall AC, Domb BG. Is there enough evidence to support hip capsular reconstruction? A systematic review of biomechanical studies. J Hip Preserv Surg 2021; 8:156-163. [PMID: 35145712 PMCID: PMC8826158 DOI: 10.1093/jhps/hnab059] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 06/09/2021] [Accepted: 07/19/2021] [Indexed: 11/30/2022] Open
Abstract
The aim of this study was to review and summarize the available biomechanical data on hip capsular reconstruction to guide clinical decision-making. A literature search was completed in December 2020 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify biomechanical cadaver studies on hip capsular reconstruction, hip capsulectomy or hip capsular defect. The investigated parameters included maximum distraction force, capsular state affecting range of motion (ROM), rotation and translation. Four studies met al. the inclusion–exclusion criteria. The median effective force for resisting maximum distraction for the reconstruction state, capsular defect state and the intact state was 171, 111 and 206 N, respectively. The defect capsule force was significantly lower (P = 0.00438) than the intact capsule force. The reconstruction state had a higher distraction force than that of the capsular defect, but due to heterogeneity, the overall effect size was not statistically significant. The capsular reconstruction state reduced excess motion and the degree of instability compared to the capsular defect state but restored the hip close to its native capsular state in the cadaveric model. When compared to capsulectomy/defect state, hip capsular reconstruction significantly improved the rotational stability and effective force at maximum distraction and minimized translation. However, no conclusions can be made regarding the most effective protocol due to the high heterogeneity between the four studies. Further biomechanical studies are needed to test various types of grafts under the same protocol.

Arthroscopic Triple Reconstruction in the Hip Joint: Restoration of Soft-Tissue Stabilizers in Revision Surgery for Gross Instability. Arthrosc Tech 2021; 10:e1239-e1248. [PMID: 34141538 PMCID: PMC8185569 DOI: 10.1016/j.eats.2021.01.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Accepted: 01/11/2021] [Indexed: 02/03/2023] Open
Abstract
Gross hip instability in an active adult with previous normal hip anatomy is usually due to disruption of the static stabilizers of the hip joint. Although such a disruption can result from a high-grade injury, it can be iatrogenic after previous hip arthroscopy. The patient may present with a painful limp and recurrent subluxation sensation in the affected hip joint. Revision hip arthroscopy in this scenario is generally complicated, and it is not uncommon for all the soft-tissue stabilizers to be compromised. The labrum, ligamentum teres (LT), and capsule of the hip joint are often so damaged that reparation is not an option. Reconstruction of the torn LT is an established method to add secondary stability while addressing the labral pathology in the hip joint with microinstability. Concomitant reconstruction of all the static restraints has yet to be described addressing triple instability. This Technical Note presents a stepwise approach, including tips and pearls, for arthroscopic triple reconstruction of the labrum, LT, and capsule. We believe this method is a safe and reproducible way to effectively treat gross hip instability in young patients.

Abstract
Complications are agonizing and leave feelings of inadequacy, insufficiency, or ineptitude. For these and other reasons, complications are not frequently reported in the literature. But reporting of complications is not only cathartic, it can be illuminating. Once out in the daylight, complications can be categorized, quantified, parsed, analyzed, and dissected with the scientific method to yield insight to enable us to prevent complications that we can avoid. Technical innovations have demonstrated ability to solve current problems. Standardizing the reporting of complications allows comparability between centers. Better data lead to better analysis and may decrease the complication rate. Recent investigations published in Arthroscopy and elsewhere have improved our understanding of hip arthroscopy complications, making the procedure safer, more effective, and of higher value.
