Abstract The efficacy and outcomes for the concurrent repair of medial meniscus posterior horn root tear (MMPHRT) during open wedge high tibial osteotomy (OWHTO) are unclear. This study compared radiologic, arthroscopic, clinical between repaired unrepaired MMPHRT OWHTO. Fifty-seven patients were prospectively enrolled from 2014 to 2016. 25 who underwent OWHTO with all-inside MMPRT using FasT-Fix (repaired group) 32 without (unrepaired a mean 2-year follow up in both groups. meniscal healing...

Bioabsorbable anchors may lead to osteolysis and cyst formation. However, the prevalence of these outcomes is not known for rotator cuff repairs.To evaluate formation after placement bioabsorbable repairs verify whether degraded as intended preserved bone stock possible revision compared with metal anchors. The null hypothesis was that rate severity around anchor are negligible.Case series; Level evidence, 4.Between April 2008 November 2011, a total 209 patients (85 men, 124 women) underwent...

High tibial osteotomy (HTO) produces valgus limb alignment, and this change can affect lower length.To compare the in length discrepancy compared with contralateral after unilateral lateral closing wedge HTO (CWHTO) medial opening (OWHTO).Randomized controlled trial; Level of evidence, 1.In study, 30 knees undergoing CWHTO OWHTO for compartmental osteoarthritis were analyzed 1-year follow-up. The length, measured preoperatively 1 year postoperatively. patients' subjective sensation of,...

It is unclear whether postoperative outcomes are associated with the cartilage regeneration after open wedge high tibial osteotomy (OWHTO) combined microfracture. The purpose of this study was to evaluate articular cartilage, radiologic, and clinical OWHTO without Eighty-seven patients who underwent from 2014 2015 were retrospectively included in study. Fifty-seven OWHTOs microfracture on medial femoral condyle (MFC) (group 1) 30 2) compared at a mean 2-year follow-up. evaluated using...

The purpose of this study was to evaluate the disparity between preoperative target correction amount and postoperative in open wedge high tibial osteotomy (OWHTO) patients divided according planned gap.Seventy-two were into two groups (group 1 with opening gap lager than mean length total group 2 a smaller gap). determined weight bearing line (WBL) ratio on whole leg radiograph. Absolute relative values WBL ratios compared order clarify whether deviated toward over- or under-correction.The...

The purpose of this study was to evaluate changes in the coronal alignment knee and ankle joints after open wedge high tibial osteotomy (OWHTO) determine factors related recurrence (R) varus deformity by serial analysis.Sixty-four OWHTOs were enrolled study. weight bearing line (WBL) ratio, joint convergence angle (JLCA), inclination, mechanical axis-tibial plateau angle, talar inclination (TI), distal tibia articular (DTAA) serially assessed. Serial correlation analysis between all...

Abstract The present study was conducted to evaluate the force distribution in knee joint during daily activities after open-wedge high tibial osteotomy (OWHTO). A three-dimensional proximal finite element model (FEM) created using Mimics software computed tomography (CT) scans of tibia OWHTO. anterior and posterior gaps were 7.0 12.1 mm, respectively, target opening angle 12 degrees. loading ratio medial lateral plateaus 6:4. To living (ADLs) OWHTO, peak von Mises stresses (PVMSs) analyzed...

Retrospective fusion level(s)-, age-, and gender-matched analysis.To determine whether the application of a topical gelatin-thrombin matrix sealant (Floseal) at end anterior cervical discectomy (ACDF) can reduce amount postoperative hemorrhage.The effect in decreasing hemorrhage following ACDF has not been reported.Matrix was (n=116, study group) or applied (n=58, control ACDF. Patients were selected by 1:2 matching criteria level(s), age, gender. Seven parameters described below compared...
