  1. Data are mean (range). P for between-group comparisons was determined using t tests
  2. CAS-TKA knees treated with computer-assisted surgery—total knee arthroplasty, Bone-Resect-TKA knees treated with intra-articular bone resection—total knee arthroplasty, IKS Score International Knee Society Score
  3. Statistically significant (P < 0.05)
