However, low-field MRI is feasible of measuring the relative position of bone and implant with comparable precision as obtained with marker-free RSA techniques.
Interestingly, results of the present study showed that low-field MRI is feasible of measuring the relative position of bone and implant with a precision which is comparable to marker-free RSA techniques.
However, low-field MRI is feasible of measuring the relative position of bone and implant with an error of μ ≤ 0.13 mm (σ ≤ 0.931 mm) for translation and μ ≤ 0.15° (σ ≤ 1.63°) for rotation when the manual registration algorithm is used, which indicates that with some improvements this technique could reach adequate precision.
Autografts and implants with banked bone continue as the treatments of choice, although each exhibits limitations and liabilities.
This systematic research has shown a growing interest in this biological treatment approach as augmentation procedure to favour integration of bone-graft, bone-graft substitutes, or bone implants with bone and soft tissues, by documenting an increasing number of published studies over time.
As biomaterials, such as bone cement and implants, closely interact with bone material, the structure property relation established here can provide a basis for better design of future biomaterials.
Moreover, because of unique properties such as high tensile strength, CNTs can act as bone substitutes and implants if filled with calcium and shaped/arranged in the bone structure [69, 70].
Systematic research showed a growing interest in this treatment approach for the integration of bone-graft, bone-graft substitutes, or bone implants, with an increasing number of published studies over time.
Both of these hurdles could potentially be overcome by introducing a number of pores in the structure of the Ti implant to match the properties of the bone as well as improve the mechanical integration between the bone and implant, and subsequently coating it with a biologically active ceramic coating to promote chemical integration.
Nevetheless, by virtue of conformity of articular surfaces in TKA, we can assume that soft tissue contacts with bone and implant surfaces are similar in a weight-bearing situation.
