Factors related to early recovery rate after partial knee meniscectomy.
A main role of clinicians treating patients after orthopedic surgery is to inform patients about their anticipated recovery rate and recovery endpoint. In estimating recovery rate, clinicians consider a series of potentially influencing factors, including the type and severity of injury and the characteristics of the patient. Unfortunately, this is done largely without evidence to support factors believed to be important in recovery rate. To our knowledge, no studies exist where factors that might influence recovery rate after arthroscopic partial meniscectomy have been evaluated. Eighty-three patients (11 women and 72 men) were evaluated 4 days after and then again 6 weeks after knee arthroscopic partial meniscectomy surgery. Recovery rate was calculated by dividing the change in a patient's Hughston Clinic knee self-assessment questionnaire during this period by his or her baseline Hughston score and relationships to independent variables (gender, age, body mass index [BMI], injury chronicity, affected meniscus, Hughston Clinic knee self-assessment score at baseline, knee flexion passive range of motion, and knee circumference). These were evaluated using backward stepwise regression analysis. The relationship between recovery rate and the independent variables was statistically significant (P,.05) for the following variables: injury chronicity, gender, and gender/injury type combination. The most unexpected finding in this study was the statistically nonsignificant relationship between recovery rate and the following variables: age, Hughston score, BMI, knee swelling, and knee flexion passive range of motion loss.
