    IV, retrospective case series.

    The aims of this study were to confirm the relationship between osseous coverage and labral size and toinvestigate the severity of intra-articular damage in borderline dysplastic hips in correlation to labral size.

    Patients treated with primary hip arthroscopy for symptomatic labral tears between 2010 and 2018 were considered for this study. Patients were included if they had preoperative radiographic measures and intraoperative assessments of the labra and cartilage. The study group was divided into borderline dysplastic and nondysplastic groups via 3 measurements lateral center edge angle (LCEA), acetabular index (Ax), and anterior center edge angle (ACEA). Undercoverage was defined as LCEA ≤ 25°, Ax ≥ 10°, and ACEA ≤ 20°. The labrum was measured in four quadrants anterosuperior (AS), anteroinferior (AI), posterosuperior (PS), and posteroinferior (PI). Additionally, to assess cartilage damage in borderline dysplastic hips, hips with average labral size in the top quartile were compared to hips with averII, case-control study.

    To evaluate the biomechanical properties of the labral suction seal in the native labrum and after rim preparation, labral augmentation, and labral reconstruction.

    Eight hemi-pelvises were dissected to the level of labrum and mounted for biomechanical testing. Each specimen was tested in axial distraction starting with the native labrum and then sequentially following rim preparation from 12 to 3 o’clock, labral augmentation, and segmental labral reconstruction using the iliotibial band allograft. In each condition, the specimens were compressed to 250 N and then distracted at 10 mm/s with force and displacement continuously recorded. Each test was repeated 3 times, and the mean peak force, displacement at peak force, and work were calculated. Data were reported as a percentage of the intact values to account for sex and size differences. Statistical testing was performed via a repeated-measures analysis of variance with a post hoc Tukey analysis.

    Peak loads occurred within 2.21 to 3.11 mm of displaceme

    The results show that the suction seal is not significantly changed following rim preparation. Relative to the rim preparation, labral augmentation may re-create the labral suction seal better than labral reconstruction.

    This study provides a biomechanical basis for surgical decision making and clinical management of patients with labral tears of the hip.

    To assess recurrent instability of the shoulder following open Latarjet performed as the primary stabilization procedure or as a salvage procedure.

    A retrospective, comparative cohort study was performed for a consecutive series of patients in the Military Health System who underwent open Latarjet from January 1, 2010, to December 31, 2018. IPI-145 All patients were diagnosed with recurrent anterior shoulder instability and had a minimum of 2 years of postoperative follow-up. Patients were categorized as either having a primary Latarjet (PL; no prior shoulder stabilization procedure) or salvage Latarjet (SL; ≥1 previous arthroscopic surgical stabilization procedures).

    A total of 234 Latarjet procedures were performed in 234 patients. The overall recurrent instability rate was 15.8% (37/234), the overall reoperation rate was 16.7% (36/234), and the overall complication rate was 14.2% (33/234) over a mean 5.0 years of follow-up. There were 99 PL procedures and 135 SL procedures. The SL group had significantly more recurrent instability than the PL group (SL 28/135, 20.7%; PL 9/99, 9.1%; P= .0158). There was no difference in overall reoperation rates (SL 26/135, 19.3%; PL 13/99, 13.1%; P= .2140) or complication rates (SL 20/135, 14.8%; PL 13/99, 13.3%; P= .9101).

    The rate of recurrent instability following the Latarjet procedure in an active, high-risk population is 15.8%. Primary Latarjet was found to have lower rates of recurrence compared with salvage Latarjet procedures (9.1% versus 20.7%).

    To assess the efficacy of platelet-rich plasma (PRP) for lateral epicondylitis and evaluate its impact on pain and functional outcomes.

    This study followed Preferred Reporting Items and Systematic Reviews and Meta-Analyses guidelines. A comprehensive literature search was conducted in September 2019 and repeated in April 2020 using electronic databases PubMed, MEDLINE, and the Cochrane Library. Baseline and 3-, 6-, and 12-month data were extracted for visual analog scale (VAS), Disabilities of the Arm, Shoulder, and Hand (DASH), and modified Mayo Clinic performance index for the elbow (MAYO) scores. Only level 1 studies with patients who had not undergone surgery were included. Outcomes data, study design, demographic variables, PRP formulation, and comparator treatments were recorded. Statistical analyses of pooled weighted mean differences (WMDs) were performed and compared with estimated minimal clinically important difference (MCID) values. The Coleman Methodology Score (CMS) was used to assess methodbsolute difference estimate for their respective MCIDs but fell short of the 10% estimate.

    Considering the small number of comparable studies, lack of quantification of specific PRP content, considerable heterogeneity between randomized control trials, and most effect sizes being equivocal within the framework of 2 estimated MCID values, the authors can neither scientifically support nor discourage the usage of PRP for lateral epicondylitis despite finding statistically significant improvements in pain and functional outcomes.

    To determine the invivo effectiveness of a single-stage surgical procedure that combines microfracture and an autologous platelet-rich fibrin (PRF) membrane for cartilage repair in a rabbit model.

    Cartilage defects were created in the trochlear groove of the knees of adult white rabbits. Defects were divided into 2 treatment groups microfracture only (control group) and microfracture covered by a PRF membrane (PRF group). To evaluate the repair cartilage, assessments were performed at 4, 12, and 24 weeks postoperatively using the International Cartilage Repair Society (ICRS) macroscopic scoring system and modified Wakitani histologic grading system.

    The mean ICRS macroscopic scores in the control and PRF groups were 4.1 and 5.8, respectively, at 4 weeks (P= .0623); 6.3 and 9.8, respectively, at 12 weeks (P= .006); and 6.5 and 10.3, respectively, at 24 weeks (P= .010). The mean modified Wakitani scores in the control and PRF groups were 4.0 and 3.9, respectively, at 4 weeks (P > .999); 5.3 and 10.4, respectively, at 12 weeks (P= .
