  To report the clinical history and preliminary outcomes of patients who underwent posterior glenoid reconstruction using a distal tibial allograft (DTA) for the management of posterior shoulder instability with glenoid bone loss.
 
  Patients who underwent posterior shoulder stabilization with a DTA in our institution between 2011 and 2019 were retrospectively reviewed. Demographic characteristics, operative reports, and clinical and functional outcomes were recorded. Outcomes included postoperative range of motion (ROM), recurrent instability, complications, and revision surgery. All patients underwent at least 1 year of follow-up, except 2 patients who underwent revision surgery. Preoperative and postoperative ROM was compared using the 2-tailed Student 
  test for paired samples.
 
  Ten patients who underwent DTA augmentation for posterior instability were included, comprising 2 female and 8 male patients with an average age of 24 years (range, 17-35 years). Five patients had a prior sports-related traumatic event, and 2 patients had a seizure disorder. Seven patients had undergone a prior stabilization procedure. The average reverse bony Bankart lesion was 26% of the glenoid diameter. Concomitant procedures included 4 capsular repairs, 2 labral repairs, 2 capsular plications, and 1 repair for humeral avulsion of the glenohumeral ligament. One patient reported recurrent instability after surgery. Two patients underwent revision surgery, with one removal of symptomatic hardware and one early revision owing to screw penetration into the glenoid. There was no significant difference in preoperative versus postoperative ROM.
 
  Posterior shoulder instability with significant bony deficiency can be managed using DTAaugmentation with good outcomes and a reasonable complication rate in these challenging cases.

  To analyze return to sports, functional outcomes, and complications following the Latarjet procedure in competitive athletes with anterior glenohumeral instability and glenoid bone loss <20%.
 
  All the included patients were operated between 2010 and 2016. The inclusion criteria were competitive athletes with anterior glenohumeral instability, a glenoid bone defect <20% who participated in contact sports, forced overhead sports, or had a previous failed Bankart repair and had a minimum 2 years' follow-up. Return to sports, range of motion (ROM), the Rowe score, and the Athletic Shoulder Outcome Scoring System score were used to assess functional outcomes. Complications and bone consolidation were also evaluated.
 
  A total of 65 athletes were included in the study. The mean follow-up was 53 months (±13), and the mean age was 23.9 years (range, 16-31 years). Overall, 94% were able to return to sports and 84% returned at the same level. No significant difference in shoulder ROM was found between preoperative and postoperative results. The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after operation (
  .001). No significant difference in shoulder ROM and functional scores was found between primary and revision cases.  https://www.selleckchem.com/products/ly333531.html  The total complication rate was 11% and the revision rate was 1.5% The recurrence rate was 4.6%. The bone block healed in 95% of the cases.
 
  In high-risk competitive athletes with anterior glenohumeral instability and glenoid bone loss <20%, the Latarjet procedure resulted in excellent functional outcomes, with most of the patients returning to sports and at the same level they had before injury with a low rate of recurrences.

  To define the time required to achieve the minimally clinically important difference (MCID), substantial clinical benefit (SCB) and patient acceptable symptomatic state (PASS) for isolated arthroscopic partial meniscectomy (APM), and define preoperative and intraoperative factors that predict both early and late achievement of the stated metrics.
 
  Patients who underwent isolated APM between 2014 and 2017 were retrospectively included. Patients without preoperative and 6-month patient-reported outcome measure scores, revision procedures, and significant concomitant procedures were excluded. The MCID, SCB, and PASS were calculated for knee-based patient-reported outcome measure scores using receiver operating curve analysis. Kaplan-Meier survival analysis established the time required to achieve MCID, SCB and PASS. Hazard ratios from multivariate Cox regression allowed for the isolation of demographic and intraoperative factors predictive of the delayed time required to achieve MCID, SCB and PASS.

  To determine whether range of motion (ROM) varies with the location and extent of labral tear seen in patients undergoing arthroscopic anterior shoulder stabilization.
 
  Consecutive patients undergoing arthroscopic anterior shoulder stabilization who were enrolled in the Multicenter Orthopaedic Outcomes Network Shoulder Instability database underwent a preoperative physical examination and intraoperative examination under anesthesia in which ROM was recorded. Intraoperatively, the location and extent of the labral tear was recorded using conventional clock-face coordinates. Patients were grouped by combinations of quadrants involved in the labral tear (G1-G7) G1= anterior only,G2= anterior+ inferior, G3= anterior+ inferior+ posterior, G4= all quadrants, G5= superior+ anterior, G6= superior+ anterior+ inferior, and G7= posterior+ superior+ anterior. Statistical analyses were performed with the Kruskal-Wallis rank-sum test. When 
  < .05, a post-hoc Dunn's test was performed. For categorical variables, the χ
  test was performed.
