Summary
Arthroscopic partial meniscectomy (APM) generally yields favorable outcomes. However, preoperative physical functional status and Worker's Compensation claims significantly predict poorer results, alongside cartilage damage.
Area of Science:
- Orthopedics
- Sports Medicine
- Biomedical Engineering
Background:
- Knee osteoarthritis is a known predictor of poor outcomes following arthroscopic partial meniscectomy (APM).
- Previous studies highlight the need to investigate other preoperative factors influencing APM outcomes.
Purpose of the Study:
- To confirm osteoarthritis as a correlate of poor outcomes after APM.
- To identify additional preoperative characteristics impacting functional status post-APM using multivariable analyses.
Main Methods:
- 105 patients undergoing APM were analyzed.
- Demographic and clinical data were extracted from medical records.
- Preoperative and follow-up functional status assessed using SF-36 and Lysholm scales.
Main Results:
- Significant improvements observed in SF-36 scores (53.7 to 18.2) and Lysholm scores (5% to 73% satisfactory).
- Multivariable analysis revealed Worker's Compensation (p=0.003), poor baseline physical function (p=0.007), and Grade III-IV cartilage damage (p=0.05) as predictors of worse outcomes.
Conclusions:
- APM demonstrates generally favorable outcomes.
- Preoperative physical functional status and Worker's Compensation status are strong predictors of post-APM function.
- Routine assessment of these factors is recommended for orthopedic outcome studies.
