Table 4 Comparison of percentage of postoperative lower limb alignment (within 3° deviation) and component alignment

From: Total knee arthroplasty in patients with Ranawat type-II valgus arthritic knee with a marked coronal femoral bowing deformity: comparison between computer-assisted surgery and intra-articular resection

  1. Data are n (%). P for between-group comparisons was determined using χ 2 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
  3. *Statistically significant (P < 0.05)
