“…There is much controversy on the benefits of cemented versus uncemented fixation techniques of TKRs. Uncemented fixation for TKR was introduced as a method of potentially increasing implant longevity [9]. The presence of a more physiological bond between the bone and the implant is considered by some to provide a stronger device [10].…”

Various approaches have been studied to engineer the implant surface to enhance bone in-growth properties, particularly using micro- and nano- topography. In this study, the behavior of osteoblast (bone) cells was analyzed in response to a titanium oxide (TiO2) nanotube-coated commercial zirconia femoral knee implant consisting of a combined surface structure of a micro-roughened surface with the nanotube coating. The osteoblast cells demonstrated high degrees of adhesion and integration into the surface of the nanotube-coated implant material, indicating preferential cell behavior on this surface when compared to the bare implant. The results of this brief study provide sufficient evidence to encourage future studies. The development of such hierarchical micro and nano topographical features, as demonstrated in this work, can provide for insightful designs for advanced bone-inducing material coatings on ceramic orthopedic implant surfaces.

“…Indeed, the minimal clinically important difference (MCID) is 7.2 points for KSS knee according to by Lizaur-Utrilla et al [ 30 ]. In the literature, some series comparing cementless and cemented fixations, report statistically higher KSS knee [ 4 , 9 ] and function scores [ 9 ] in the cementless group, as in the Hu et al’s meta-analysis [ 31 ] but none of them are higher than the MCID. The other studies did not report significant difference.…”

“…On the one hand, cemented fixation advantages are the instantaneous, spontaneous, and strong primary fixation after acrylic cement polymerization [ 6 ], and the possibility to correct a slightly inaccurate bone cut by the cement thickness, with excellent clinical results and survival rate at 20-year follow-up (FU) in several series [ 7 , 8 ], but on the other hand, cementless fixation allows mechanical and biological fixation by bony ingrowth on the implant surface, reduction of operating time and an osseointegration that would allow a durable fixation [ 2 , 4 , 9 ]. Outcomes at long-term follow-up are also excellent [ 8 , 10 ].…”

Introduction: Knee osteoarthritis is the main indication for primary total knee arthroplasty (TKA). It is now accepted that cementless implantation of the femoral component provides equivalent results to cemented one, however, the optimal fixation method of the tibial component remains controversial. The purpose of this study was to compare the survivorship of cemented versus cementless tibial baseplate in primary total knee arthroplasty. Materials and methods: We carried out a retrospective, monocentric study, including 109 TKA (Zimmer® Natural Knee II ultra-congruent mobile-bearing) implanted between 2004 and 2010 for primary osteoarthritis, comparing 2 groups depending on tibial component fixation method, one cemented (n = 68) and one cementless (n = 41). Clinical (Knee Society Rating System (KSS), Hospital for Special Surgery (HSS) scores, range of motion) and radiodiological outcomes were assessed at last follow-up with a minimal follow-up of 5 years. Results: Mean follow-up were 8.14 [5.31–12.7] and 8.06 [5.22–12.02] years, respectively, in cemented and cementless groups. The tibial component survival rate was 100% [95CI: 91.4–100] in the cementless group and 97.1% [95CI: 89.78–99.42] in the cemented group (2 aseptic loosenings) (p = 0.27). Radiolucent lines were present in 31.7% (n = 13) of the cementless and 44.1% (n = 30) of the cemented baseplates (p = 0.2). The postoperative KSS knee score was higher in the cementless group (99 ± 3 vs. 97 ± 7.5; p = 0.02), but there was no significant difference in KSS function, global KSS and HSS scores. Mean range of flexion was 120 ± 10° in the cementless group and 122.5 ± 15° in the cemented group (p = 0.37). No significant differences were found on the radiographic data or on complications. Conclusion: In this study, the survival rate of the tibial component is not influenced by its fixation method at a mean follow-up of 8 years in osteoarthritis, which confirms the reliability of cementless fixation in primary TKA.

Complications from total knee arthroplasty caused by the implanted material are rare, with the exception of polyethylene wear. Descriptions of screw migration into the knee joint cavity are very rare. The authors report intra-articular migration of a polyethylene safety screw in a case of total knee arthroplasty, with sacrifice of the posterior cruciate ligament (TKA Performance; Biomet, Warsaw, IN, USA), which necessitated new surgery to remove the screw, replace the polyethylene insert and emplace a new fixation screw.
