Clinical Results in Posterior-Stabilized Total Knee Arthroplasty with Cementless Tibial Component in Porous Tantalum: Comparison between Monoblock and Two Pegs vs. Modular and Three Pegs

Nowadays, total knee arthroplasty (TKA) is widely considered to be the gold standard for treatment of end-stage osteoarthritis. Although optimal mode fixation in TKA continues an important area investigation, cementless offers possibility gain biologic fixation, preserve bone stock and mineral density, potentially improve survivorship. The purpose this retrospective study was evaluate clinical results a posterior-stabilized with tibial component porous tantalum, comparing two groups: Group A (30 patients), monoblock pegs, B (22 modular three pegs. Knee Society Score (KSS) Injury Osteoarthritis Outcome (KOOS) were submitted patients, radiographs collected at last follow-up. mean follow-up 26.32 (20–40) months. Significant differences not detected between postoperative KSS values groups (p = 0.44). Evaluating KOOS outcomes, we found that rating system showed statistically significant improvement from preoperative average 51.4 (SD ± 15) 72.66 19) final < 0.05).
