Meta Analysis Comparative StudySuture versus screw fixation technique for tibial eminence fracture: A meta-analysis of laboratory studies.
The aim of this study was to compare the biomechanical properties between the suture fixation technique and the screw fixation technique for tibial eminence fracture (TEF). ⋯ The FiberWire suture fixation may be biomechanically superior to a single screw fixation in TEF treatment in mature knees regarding ultimate failure load, while no significant difference was found between the two fixations in terms of stiffness and displacement after the cyclic testing.

Meta Analysis Comparative StudyConservative versus repair of medial patellofemoral ligament for the treatment of patients with acute primary patellar dislocations: A systematic review and meta-analysis.
The aim of this study was to perform a meta-analysis to compare the effects of repair of medial patellofemoral ligament (MPFL) and conservative treatment in patients with acute primary patellar dislocation (PPD). ⋯ Based on the available data, MPFL repair did not reduce the risk of redislocation nor did it produce any significantly better outcome based on the clinical manifestations, including anterior knee pain and knee activities. Only the Kujala score was improved by MPFL repair compared with conservative treatment.

Comparative StudyThree-dimensional measurement of the course of the radial nerve at the posterior humeral shaft: An in vivo anatomical study.
Iatrogenic radial nerve injury caused by surgical exposure of the humerus is a serious complication. We aimed to describe the course of the radial nerve at the posterior humeral shaft using a three-dimensional (3D) reconstruction technique by utilizing computed tomography (CT) images of living subjects. We hypothesized that the course of the radial nerve in the posterior aspect of the humeral shaft would be reliably established using this technique and the measurements would have satisfactory intraobserver/interobserver reliabilities. ⋯ The course of the radial nerve at the posterior aspect of the humeral shaft can be reliably established using the 3D reconstruction technique, and all measurements had excellent intraobserver/interobserver reliability.

Preoperative denosumab treatment with curettage may be a risk factor for recurrence of giant cell tumor of bone.
Giant cell tumor of bone (GCTB) is a local aggressive bone tumor, histologically classified as intermediate malignancy. Recently, the RANKL inhibitor, denosumab, was developed as a novel and effective treatment option for GCTB. Since the risk of preoperative use of denosumab with curettage had been previously reported, this study aimed to investigate the relationship between recurrences and clinicopathological features associated with adjuvant denosumab treatment in GCTB. ⋯ Our findings revealed the use of denosumab in GCTB, prior to curettage, to possibly increase the risk of local recurrence. Together with previous reports, our finding might provide information for beneficial treatment of GCTB.

Randomized Controlled TrialComparison of epidural anesthesia with chloroprocaine and lidocaine for outpatient knee arthroscopy.
This study aimed to compare clinical efficacy and safety of chloroprocaine and lidocaine in epidural anesthesia for outpatient knee arthroscopy. Eighty patients undergoing knee arthroscopy were randomly allocated to receive 3% 2-chloroprocaine (group C, n = 40) or 2% lidocaine (group L, n = 40) for epidural block. Latency to anesthesia onset, highest block level, time to achieve peak effect, time to complete sensory and motor block regression, vital signs including respiration and hemodynamics, and complications during follow-up were recorded. ⋯ No adverse effects or neurologic complications were found in both groups. In conclusion, epidural chloroprocaine elicits rapid anesthetic effects, fast sensor and motor block, and faster recovery of motor function compared to lidocaine. These characteristics make chloroprocaine better than lidocaine as the choice of epidural anesthesia in short clinical operations such as knee arthroscopy.
