Abstract
Introduction: Meniscus surgery is one of the most commonly performed orthopedic surgical procedures in the United States. However, outcomes following a Total Knee Arthroplasty (TKA) in patients with a history of prior knee arthroscopy are varied with small patient cohorts, warranting further research. The research question investigates how the clinical outcomes of TKA compare between patients with and without prior meniscectomy history. It is hypothesized that there will be no significant difference in clinical outcomes between the two cohorts.
Methods: The study design is a retrospective case-control study. The study population included patients from Rothman Institute with TKA and prior meniscal surgery on the ipsilateral knee. Patients were matched on a 2:1 basis to the control group undergoing TKA without meniscal history. Physician chart notes, operative reports, and images were reviewed to compare outcomes. The outcomes were based on postoperative complications, including the rate of revision, re-operation, infection, and clinical outcome score.
Results: 1028 patients met the inclusion criteria for the study population and were available for analysis. To date, 111 patients have been analyzed. Preliminary data shows that 97% (108) of the study population experienced no TKA complications. 2.7% (3) of the analyzed patients experienced TKA complications, warranting revision. Statistical analysis between the study and control group complication rates is pending.
Discussion: The results implicate that there is no statistical difference between the two cohorts, which may support the hypothesis. This data might serve as a point of education for TKA patients and provide modifiable risk factors for meniscectomy patients.
