title: Predictors of the Clinical Outcome After Arthroscopic Partial Meniscectomy for Acute Trauma-Related Symptomatic Medial Meniscal Tear in Patients More Than 60 Years of Age.
abstract: To determine predictors of the clinical outcome after arthroscopic partial meniscectomy performed for acute trauma-related medial meniscal tear leading to mechanical symptoms in patients more than 60 years of age.
  
  
  
  In this retrospective study with 4.1 years' follow-up, the clinical data of 154 arthroscopic partial medial meniscectomies were evaluated. The body mass index (BMI), duration of symptoms, the hip-knee-ankle angle, type of the meniscal tear, presence of any chondral lesions, degenerative changes in the patellofemoral joint, the status of the cruciate ligaments and lateral meniscus, and the presence of any plica or synovitis were the independent variables. Visual Analog Scale (VAS) and Lysholm Knee Scoring Scale were the instruments used as outcome measures. Multivariate analysis was performed to determine the major predictors.
  
  
  
  The mean VAS score for 154 knees evaluated in this study improved from 5.6 points preoperatively to 2.3 points at the latest follow-up. The mean Lysholm score improved from 43 points to 72.7 points. VAS and Lysholm scores at the latest follow-up were significantly worse in patients with a preoperative BMI ≥ 26 kg/m(2), hip-knee-ankle angle > 5°, grade III or IV chondral lesion of the medial compartment according to Outerbridge classification, degenerative changes in patellofemoral joint surfaces, and an anterior cruciate ligament that was either partially ruptured or degenerative with increased laxity.
  
  
  
  A preoperative BMI ≥ 26 kg/m(2), Outerbridge grade III or IV chondral lesion of the medial compartment of the operated knee joint diagnosed during arthroscopic intervention, degenerative changes in patellofemoral joint surfaces, and the presence of an anterior cruciate ligament either partially ruptured or degenerative with increased laxity should be considered as the major predictors of the clinical outcome after arthroscopic partial meniscectomy performed for acute trauma-related symptomatic medial meniscal tear in patients more than 60 years of age.
