Abstract Purpose We aimed to evaluate the longitudinal changes in medial meniscus extrusion (MME) and clinical scores at multiple time points up 3 years after pullout repair for posterior root tears (MMPRTs). Methods This retrospective case series study included 64 patients who underwent MMPRTs four MRI evaluations (preoperatively months, 1 year, postoperatively). MME was measured during same points. Clinical were assessed times: preoperatively 1, 2, postoperatively. Additionally, a...
Ramp lesions are characteristic medial meniscus injuries seen in anterior cruciate ligament-injured knees. Anterior ligament combined with ramp increase the amount of tibial translation and external rotation. Therefore, diagnosis treatment have received increasing attention. However, can be difficult to diagnose on preoperative magnetic resonance imaging. Additionally, observe treat intraoperatively posteromedial compartment. Although good results been reported use a suture hook through...
Abstract Purpose The second‐look arthroscopic score of pullout repair for medial meniscus posterior root tears (MMPRTs) is associated with contemporaneous clinical scores and progression cartilage damage. However, the relationship among these scores, midterm magnetic resonance imaging (MRI) evaluations unknown. between at 1 year or MRI 3 years was evaluated. Methods Sixty‐three patients were included. Medial extrusion (MME) evaluated preoperatively postoperatively. Clinical preoperatively,...
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...
The use of various strategies for arthroscopic meniscal repairs to save the meniscus and prevent progression knee osteoarthritis has gradually increased. We investigated frequency treatments short-term clinical outcomes symptomatic isolated medial (MM) injuries. This retrospective observational study included 193 patients (197 knees) who underwent treatment MM injuries between January 2016 April 2019. Arthroscopic were divided into two groups: transtibial pullout posterior root tears...
This study aimed to evaluate the association between progression of medial joint space (MJS) narrowing, meniscus extrusion (MME) and clinical scores tibial tunnel position in pullout repairs for posterior root tears (MMPRTs).
Medial meniscus (MM) posterior root tears (PRT) cause pathological medial extrusion (MMME) and (MMPE), particularly during knee flexion, leading to rapidly progressive osteoarthritis. We investigated pre- postoperative MM using three-dimensional open magnetic resonance imaging (MRI) following two pullout repair techniques: simple stitches (TSS) TSS with an additional all-inside suture the posteromedial capsule (TSS-PM). hypothesized that TSS-PM would decrease more effectively than TSS.
Abstract Purpose Medial meniscus (MM) posterior root tears (PRT) can lead to excessive knee loading and unsatisfactory clinical outcomes after non-operative treatment or meniscectomy. Although favourable MM (PR) repair have been reported, no study has specifically investigated the of different types MMPRT. This aimed compare patients with complete radial oblique MMPRT following MMPR repair. Methods Forty who had undergone were retrospectively investigated. Patients type 2 (20 knees) 4...
Abstract Introduction The outcomes of unicompartmental knee arthroplasty (UKA) in the presence and absence medial meniscus posterior root tears (MMPRTs) have not been compared. This study compared characteristics clinical patients undergoing UKA with without MMPRTs. Materials methods analyzed 68 patients. or MMPRTs was evaluated using preoperative magnetic resonance imaging. Patient characteristics, scores before surgery at final evaluation, imaging findings were between Multiple regression...
This study aimed to compare medial meniscus extrusion (MME) in patients with partial posterior root tears (MMPRTs) through magnetic resonance imaging (MRI) conducted at two-time points and determine whether patient characteristics or MME measurements differ who respond nonoperative treatment compared those require surgical treatment.Thirty-seven MMPRTs underwent two MRI scans during management before pull-out repair. Among these, 17 received management, 20 Partial were diagnosed based on the...
