OBJECTIVE: The purpose of this study is to evaluate and define what is considered an adequate radiographic correction in arthroscopic osteochondroplasty for FAI and to secondarily assess how radiographic outcomes relate to patient reported outcomes and complications.
METHODS: The databases EMBASE, PubMed, and MEDLINE were searched for relevant literature from database inception until January 2021. Studies were screened by two reviewers independently and in duplicate for studies reporting on post-operative radiographic outcomes in arthroscopic osteochondroplasty for FAI. Data on radiographic outcomes as well as data reporting functional outcomes and complications were recorded. A meta-analysis was used to combine the mean pre- and post-operative radiographic outcomes using a random effects model. A risk of bias assessment was performed for all included studies using the MINORS score.
RESULTS: The most commonly reported radiographic outcome was the alpha angle with a pooled mean post-operative angle of 44° (95% CI 41°-46°), and mean pre- to post-surgical difference of - 19° (- 22 to - 16, I2 = 96%), followed by the LCEA with a pooled mean post-operative angle of 30° (95% CI 29-31) and mean difference after surgery of - 4° (- 6 to - 1, I2 = 97%,). Eleven studies reported on the correlation between radiographic and clinical outcomes with no consistent consensus correlation found amongst the included studies. Similarly, six studies correlated radiographic outcomes with conversion to THA with no consistent consensus correlation found amongst the included studies.
CONCLUSIONS: Based on this review, the main conclusion is that there is no consensus definition on the optimal radiographic correction for FAI and there was no consistent correlation between radiographic correction and functional outcomes. However, based on the uniform improvement in functional outcomes, this review suggests a post-operative alpha angle target of 44° with a correction target of 19° and LCEA target of 30° with a correction target of 3°.
METHODS: IV.

BACKGROUND: With the evolution of hip arthroscopy has come an increased recognition of intra-articular hip pathologies and improved techniques for their management. Whereas mechanical problems can often be corrected through surgery, functional deficits must be corrected through the rehabilitation process. Therefore, the evolution of hip arthroscopy has necessitated a progression in hip rehabilitation to ensure optimal postsurgical results.
METHODS: Literature review was conducted with PubMed, EMBASE, and PEDro (1992 to 2009) with the terms hip, rehabilitation, and physical therapy.
RESULTS: Although it is generally accepted that rehabilitation after hip arthroscopy is important, there is limited evidence-based research to support the rehabilitative guidelines.
CONCLUSIONS: The common goal of hip rehabilitation should remain focused on the return to pain-free function of the hip joint. Outcome data indicate that this goal is being met; however, further data are required to completely validate the long-term success of hip rehabilitation after arthroscopy.
