Untreated or overlooked medial meniscus posterior root tears (MMPRTs) induce sequential knee joint degradation. We evaluated epidemiological features of acute MMPRT for its early detection and accurate diagnosis.Among 330 patients from 2018 to 2020, those who underwent arthroscopic pullout repairs were enrolled. Patients non-operative treatment arthroplasty, with a cruciate ligament-deficient advanced osteoarthritis the knee, insufficient data excluded. Finally, we retrospectively 234 MMPRTs...

This study aimed to assess quadriceps muscle strength after medial meniscus (MM) posterior root repair and determine its relationship with clinical scores MM extrusion (MME).Thirty patients who underwent pullout for tear were evaluated preoperatively at 1 year postoperatively included in this study. Quadriceps was measured using the Locomo Scan-II instrument (ALCARE, Tokyo, Japan). MME (i.e., Knee Injury Osteoarthritis Outcome Score [KOOS], International Documentation Committee score,...
Introduction Implant technology for total hip arthroplasty (THA) was developed to improve function and patient satisfaction. Actis (DePuy Synthes, Warsaw, IN, USA) is a short fit-and-fill titanium stem, with medial-collared triple-taper (MCTT) geometry, that fully coated hydroxyapatite (HA). We evaluated the radiographic clinical outcomes of Total Hip System during mean follow-up five years. Patients methods retrospectively analyzed data from 80 patients (14 male 66 female, age: 65 ± 8.4...
Abstract Purpose To assess postoperative progression of patellofemoral (PF) cartilage degeneration after medial meniscus posterior root (MMPR) repair and identify potential risk factors. Methods Data from patients who underwent transtibial pullout for complete radial MMPR tears between April 2018 October 2021 were retrospectively investigated. Patients with severe chondral lesions the PF joint at primary surgery excluded. All second‐look arthroscopy 12 months postoperatively. Postoperative...
Abstract Background We investigated whether the preoperative flexion tear gap (FTG) observed in open magnetic resonance imaging (MRI) affects meniscus stability after medial (MM) posterior root (MMPR) repairs. Furthermore, time-correlated MRI findings from MMPR occurrence were evaluated. Methods This retrospective observational study included 54 patients (mean age, 64.6 years; 13 males and 41 females) who underwent pullout repair for radial degenerative tear. Meniscus (scored 0–4 points) was...
Posterior root repair of the medial meniscus (MM) can prevent rapid progression knee osteoarthritis in patients with a MM posterior tear (MMPRT). The anatomic reattachment is considered to be critical transtibial pullout repair. However, tibial tunnel creation at attachment technically difficult. We hypothesized that newly developed point-contact aiming guide [Unicorn Meniscal Root (UMR) guide] create better position rather than previously designed MMPRT guide. aim this study was compare...
