Two- to 12-year evaluation of cementless Buechel-Pappas total hip arthroplasty

Retrieval analysis of TiN (titanium nitride) coated knee replacements: Coating wear and degradation in vivo

“…There are several limitations to this study, most importantly, the low number of examined components with a relatively short in vivo service time. It is very difficult to collect such retrievals because TiN coated implants are not routinely used in large groups of patients (Breugem et al, ; Buechel Sr et al, ; Buechel Sr et al, ; Park et al, ; Thienpont, ; Van Hove et al, ). This is reflected by lack of registry data and a small body of literature regarding Ti(Nb)N coated arthroplasties, and retrieval studies focused on such implants also involved small sample numbers (Bone & Naylor, ; Fabry et al, ; Harman et al, ; Khatkar et al, ; Łapaj et al, ; Łapaj, Markuszewski, et al, ; Malviya et al, ; Raimondi & Pietrabissa, ).…”

“…Conflicting results were presented in a simulator study where severe wear of the TiNbN coating was observed on femoral components during 5 million cycles of testing (Haider et al, ). There is more data regarding the performance of Ti(Nb)N coatings in total hip replacements (THRs) with most studies reporting good clinical outcomes (Buechel Sr et al, ; Harman et al, ; Khatkar et al, ; Łapaj et al, ; Łapaj, Markuszewski, et al, ; Malviya, Lobaz, & Holland, ; Pappas et al, ; Raimondi & Pietrabissa, ; Weisenburger, Haider, & Garvin, ). Some publications documented gross wear of the coating in vivo, whereas one study indicated good wear resistance, but an inconsistent coating quality and presence of various defects (Harman et al, ; Khatkar et al, ; Łapaj et al, ; Raimondi & Pietrabissa, ).…”

Ceramics and ceramic coatings in orthopaedics

“…The first of these was PVD deposited titanium nitride (TiN) on titanium. It was developed and introduced into the marketplace for total joint arthroplasty beginning in the late 1980s [128] with formal clinical investigations beginning in 1990 [129][130][131]. At about this same time, another hard coating, diamond-like carbon (DLC), was applied to titanium implants for shoulder, ankle, and knee arthroplastic devices in Europe.…”

The effects of total ankle replacement on gait disability: Analysis of energetic and mechanical variables

“…The new generation of prostheses has shown improved clinical outcomes [6][7][8][9][10]. Several studies have shown near normal kinematics of the ankle joint after TAR in cadavers [11][12][13].…”
