Comparative StudyNo difference between knotless sutures and suture anchors in arthroscopic repair of Bankart lesions in collision athletes.
The purpose of this study was to compare the clinical results of knotless and knot-tying suture anchors in arthroscopic Bankart repair of collision athletes. Thirty-eight athletes underwent arthroscopic Bankart repairs. The mean age of the patients at the time of surgery was 23 years. ⋯ At the end of 40 months follow-up, both the knot-tying and the knotless suture anchor groups had similar postoperative results. There were no differences between Knot-Tying and Knotless repair about late disengagement and re-dislocation in this patient group. Knotless repair provided secure and low-profile repair without introducing complexities to the procedure of arthroscopic knot tying one.

Comparative StudyRupture of the anterior cruciate ligament in children: early reconstruction with open physes or delayed reconstruction to skeletal maturity?
The purpose of this study was to compare two different strategies of management for ACL rupture in skeletally immature patient. In group 1, patients were treated in a children hospital by ACL reconstruction with open physis. In group 2, patients were treated in an adult hospital by delayed reconstruction at skeletal maturity assessed radiologically. ⋯ At 27 months mean follow-up, a best subjective IKDC score was found in group 1. Objective IKDC and radiological results were similar in both groups. Early ACL reconstruction is therefore a recommended option.

Validity and responsiveness of the test of athletes with knee injuries: the new criterion based functional performance test instrument.
The purpose of this study was to evaluate the validity and responsiveness of the new criterion-based test instrument test for athletes with knee-injuries (TAK) which has been evaluated for reliability in an earlier study. Thirty-five subjects between 18 and 50 years were included in the study. They were all anterior cruciate ligament (ACL)-reconstructed and operated with hamstrings graft. ⋯ The total points for TAK/patients' assessment and TAK/physiotherapist's assessment showed large effect size (1.08 and 1.03), respectively. IKDC/total score and SF-36 scale physical functioning showed moderate effect size (0.79 and 0.41), respectively. The result of this study showed that the TAK is a reliable instrument with a large effect size for changes over time, indicating that the TAK is a very sensitive functional test instrument assessing the ACL-reconstructed patients during the rehabilitation period.

Is previous knee arthroscopy related to worse results in primary total knee arthroplasty?
According to literature, knee arthroscopy is a minimal invasive surgery performed for minor surgical trauma, reduced morbidity and shortens the hospitalization period. Therefore, this type of surgery before total knee arthroplasty (TKA) could be considered a minor procedure with minimum postoperative complication. A retrospective and cohort series of 1,474 primary TKA was performed with re-assessment after a minimum follow-up period of 2 years: 1,119 primary TKA had no previous surgery (group A) and 60 primary TKA had arthroscopic debridement (group B). ⋯ However, statistical analysis did not reveal a direct correlation between arthroscopy/primary TKA interval and postoperative complications/failures (P = 0.55). The Kaplan-Meier survival curves showed a survival rate of 98.1 and 86.8% at 10 years follow-up for groups A and B, respectively. Our data allow us to conclude that previous knee arthroscopy should be considered a factor related to postoperative primary TKA outcomes as demonstrated by the higher rate of postoperative complications and failures (P < 0.001) as well as a worse survival curve than group A.

A predictive factor for acquiring an ideal lower limb realignment after opening-wedge high tibial osteotomy.
Obtaining a correct postoperative limb alignment is an important factor in achieving a successful clinical outcome after an opening-wedge high tibial osteotomy (OWHTO). To better predict some of the aspects that impact upon the clinical outcomes following this procedure, including postoperative correction loss and over correction, we examined the changes in the frontal plane of the lower limb in a cohort of patients who had undergone OWHTO using radiography. Forty-two knees from 33 patients (23 cases of osteoarthritis and 10 of osteonecrosis) underwent a valgus realignment OWHTO procedure and were radiographically assessed for changes that occurred pre- and post-surgery. ⋯ There were significant differences in the delta angle [DA; calculated as (pre FTA - post FTA) - (pre TV - post TV)] among each group of patients. Our results thus indicate a negative correlation between the DA and preoperative TA (R(2) = 0.148, p < 0.05). Hence, given that the correction errors in our patients appear to negatively correlate with the preoperative TA, postoperative malalignments are likely to be predictable prior to surgery.
