      Associated With Worse Short-Term Outcomes.

AB  - BACKGROUND: Patients undergoing total knee arthroplasty (TKA) who have prior 
      meniscectomy may have increased rates of postoperative infection, arthrofibrosis, 
      and revision. However, aside from an increased risk of complications, it is 
      unclear whether prior meniscectomy impacts functional outcomes after TKA. This 
      study was conducted to compare functional outcomes following TKA in patients who 
      did and did not have a prior meniscectomy. We hypothesized that patients who had 
      a prior ipsilateral meniscectomy would have worse functional outcomes after 
      undergoing TKA. METHODS: A retrospective matched case-control study was conducted 
      at a tertiary academic center. Patients who underwent both meniscectomy and TKA 
      (cases) or TKA alone (controls) from 2013 to 2020 were identified from our 
      institutional database using current procedural terminology codes. Cases were 
      matched in a 1:3 ratio to controls using age, sex, race, body mass index, and a 
      comorbidity index. Inclusion criteria comprised a minimum of 1-year follow-up for 
      the Knee Injury and Osteoarthritis Outcome Score Junior (KOOS-JR). Exclusion 
      criteria included patients undergoing revision TKA and patients who had a history 
      of ligamentous knee surgery or fracture. T- and Chi-squared analyses were 
      conducted, with significance threshold being P < .05. A total of 589 cases and 
      1,767 controls were included after matching. There were no significant 
      differences in demographic variables. Cases underwent TKA after their 
      meniscectomy at a mean of 2.9 years (range: 42 days to 16 years). RESULTS: While 
      no significant difference existed for preoperative KOOS-JR scores (46.4 versus 
      46.4; P = .984), postoperative KOOS-JR scores were significantly lower in the 
      case group (71.9 versus 75.3; P = .001). The case group also achieved the KOOS-JR 
      minimal clinically important difference (MCID) and patient acceptable symptom 
      state (PASS) at significantly lower rates than the control group [(MCID: 71.0 
      versus 77.3%; P = .011) (PASS: 69.4 versus 76.7%; P = .001);]. CONCLUSION: 
      Patients who had a prior meniscectomy may experience lower postoperative 
      functional outcome scores after TKA and had a lower rate of achieving the MCID 
      and PASS for KOOS-JR. Patient expectations should be adjusted accordingly.
