Postoperative Kujala scores for isolated trochleoplasty ranged from 80 to 92, whereas those for combined stabilization procedures ranged from 76 to 95. The dislocation rate among the studies ranged from 0 to 8%. There was a persistent J-sign in 0 to 12% of treated knees among all studies, and a persistent apprehension test in 0 to 29% of treated knees. Return to play ranged from 65% to 83% in studies in which this was reported as an outcome.
 
  Sulcus-deepening trochleoplasty performed for recurrent patellar instability in the setting of trochlear dysplasia results in improved Kujala scores and a low redislocation rate, when performed as an isolated procedure or in combination with other stabilization procedures. Greater-level evidence is needed to better evaluate the overall efficacy of this procedure in addressing patellar instability.

  The purpose of this study is to identify and summarize the current utility of intraoperative ultrasound (US) during hip arthroscopy.
 
  A systematic database query of the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, EMBASE, PubMed (1980 to 2019), and Ovid MEDLINE (1980 to 2019) was performed. After article identification, descriptions of the surgical procedure, use of intraoperative US, procedural complications, and conclusions from each article were recorded and summarized.
 
  Five studies met inclusion criteria, all of which were surgical techniques or technical notes.  https://www.selleckchem.com/products/SB-743921.html  Four of the 5 studies described US used for placement of arthroscopic portals, and 1 described the use of an intraarticular US catheter for the assessment of an osteochondritis dissecans (OCD) lesion. Of the 4 studies using US for portal placement, 3 were performed supine and 1 was performed in the lateral decubitus position. All studies recognized the need for additional US training or the required assistance of a radiologist to incorporate US into a surgical practice.
 
  Descriptions of intraoperative US during hip arthroscopy are limited in the literature. However, existing technique reports demonstrate the feasibility of US for both portal placement with superficial probes and limited evaluation of cartilage using intraarticular US catheters.

  To evaluate the effectiveness of various graft options for anterior cruciate ligament reconstruction using network meta-analysis.
 
  A medical literature search was conducted of PubMed, the Cochrane Library, Embase, SCOPUS, and Web of Science from their inception through March 1, 2019. The outcomes, including International Knee Documentation Committee (IKDC) form, Lachman test, Lysholm score, Pivot shift test, and Tegner score, were evaluated among graft options. Data extraction was carried out according to inclusion and exclusion criteria, and a network meta-analysis was performed using STATA 14.0.
 
  A total of 45 trials with 3992 patients were included. The forest plots revealed no significant differences in IKDC, Lysholm, or Tegner score among the grafts. In Lachman score, a significant difference was found in the comparisons of hamstring tendon allograft (HT-AL) versus patellar tendon autograft (PT-AU) and HT-AL versus hamstring tendon autograft (HT-AU). In pivot shift test, PT-AU was superior to all the other grafts, and quadriceps tendon autograft (QT-AU) was superior to HT-AL and artificial ligament (Art-L) in the number of cases with negative results. According to surface under the cumulative ranking area (SUCRA), PT-AU had the highest probability to be the best intervention in Lachman test and Tegner score; tibialis anterior tendon allograft (TA-AL) in IKDC and Lysholm score; and QT-AU in pivot shift test. Based on the cluster analysis of SUCRA, PT-AU was considered the most appropriate intervention by IKDC and Lachman test.
 
  This study suggests that PT-AU may be the most appropriate graft for ACL reconstruction according to IKDC and Lachman test results.

  The purpose of this systematic review was to examine the effect that sex has on recurrence of anterior shoulder instability following primary arthroscopic anterior shoulder stabilization.
 
  A systematic review using PRISMA guidelines was performed by searching PubMed, Embase and Cochrane Library databases to identify studies reporting recurrence rates following arthroscopic anterior shoulder stabilization with a minimum follow-up period of 2 years. Patient demographics as well as preoperative, intraoperative and postoperative findings, including patient-reported outcomes and recurrence rates, were analyzed by 2 independent reviewers. Recurrence was defined as an episode of dislocation, subluxation or instability following primary arthroscopic anterior shoulder stabilization. Study methodological quality was evaluated with the Modified Coleman Methodology Score (MCMS). Risk bias was evaluated using the Methodological Index for Non-randomized Studies (MINORS score). Descriptive statistics are presented.
 
  Ten studies (1 Level I, 1 Level II, 5 Level III, and 3 Level IV), including a total of 7,102 patients with primary traumatic and/or recurrent traumatic shoulder instability without previous procedures who underwent primary arthroscopic anterior shoulder stabilization, were included (mean follow-up, 34.6 months; mean age, 25.4 years). There was a total of 5,097 males (71.8%) and 2,005 females (28.2%). There was a higher recurrence rate in males (6%-37%) compared to females (0-32%). Clinical outcomes were inconsistently reported, so no quantitative analysis of clinical outcomes or return-to-sport between sexes was possible. The average MCMS of all 10 studies was 76.8 ± 8.0, indicating good methodology.
 
  Males may have higher recurrence rates than females following primary arthroscopic anterior shoulder stabilization; however, the heterogeneity of the included studies precludes any definitive conclusions.
