Editorial Commentary: Both Femoral Acetabular Anteversion and Retroversion May Contribute to the Effect of Femoroacetabular Impingement: What's Your Version?

Femoral anteversion may be a protective factor for hip impingement, whereas hip arthroscopy outcomes are worse for patients with femoral retroversion. Changes in version also affect the location of impingement. The association of increased anteversion with cam lesions may also explain the high number of patients with asymptomatic cam lesions. Thus, some patients may have large α angles but be asymptomatic. Finally, although femoral version is important, it must be considered in the setting of the patient's acetabular morphology. There is a complex interplay of femoral and acetabular morphologies.

Editorial Commentary: Hip Femoroacetabular Impingement Emotional Impact and Mental Health: An Arthroscope Can't Fix Everything.

Arthroscopic treatment of femoroacetabular impingement is increasingly common with established clinical success. As with other chronic injuries, there is an emotional impact that can affect recovery, particularly in competitive athletes. As this emotional aspect of injury is more recognized, it will be important to determine comprehensive means of treating both an athlete's physical and mental health. It is important to establish preoperative expectations. For certain patients, psychological evaluation and treatment is indicated early in the diagnosis and recovery to ensure mental fitness, and this may be especially true for adolescents. A comprehensive and personalized approach to injury recovery is optimal.

The Treatment of Adult Osteochondritis Dissecans with Autologous Cartilage Implantation: A Systematic Review.

We sought to evaluate the effectiveness of autologous chondrocyte implantation (ACI) for the treatment of adult osteochondritis dissecans (OCD) lesions according to patient-reported outcomes, complication rates, and failure rates. A search of MEDLINE, Scopus, and Cochrane Library was performed to identify clinical studies (levels I-IV) reporting outcomes after ACI treatment for OCD in adult knees. Our inclusion criteria included the following: (1) published between January 2000 and April 2017, (2) stable and unstable OCD lesions of the knee, (3) use of ACI in at least one group, (4) subjects ≥18 years old or skeletally mature, (5) inclusion of at least one patient-reported clinical outcome measure, and (6) written in English. A total of nine studies (179 patients), mean age of 27.6 years (range: 18-49 years), were included. There were 227 OCD lesions with an average size of 4.1 cm2 (range: 1.2-9.4 cm2). The average follow-up was 61.3 months (range: 6.5-120 months). In general, there was significant improvement in symptoms, but better results occurred among active male patients with smaller lesions as well as younger patients. Statistically significant improvement in patient-reported outcomes was reported in all studies. There were 23 complications reported (15.6%), including 12 failures (8.2%). Significant improvement in clinical outcome measures demonstrates clinical efficacy of autologous cartilage therapies for the treatment of OCD in adult patients. Better outcomes are often observed with males, active patients, smaller lesion sizes, and younger age at the time of surgery.
