Medium-term results of the AMC-unicompartmental knee arthroplasty

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

“…Although TiN coatings have been used in arthroplasty for many decades, there is very little data available regarding their performance in knee replacements (Bone & Naylor, ; Breugem et al, ; Buechel Sr et al, ; Buechel Sr et al, ; Fabry et al, ; Haider et al, ; Harman et al, ; Łapaj et al, ; Łapaj, Markuszewski, et al, ; Lappalainen & Santavirta, ; Malviya et al, ; Mohammed et al, ; Österle et al, ; Park et al, ; Park et al, ; Raimondi & Pietrabissa, ; Reich et al, ; Saxler et al, ; Serro et al, ; Sonntag, Reinders, & Kretzer, ; Subramanian, Muraleedharan, Ananthakumar, & Jayachandran, ; Weisenburger et al, ). Clinical studies indicated comparable mid‐term outcomes of Ti(Nb)N coated and conventional knee arthroplasties (Breugem et al, ; Mohammed et al, ; Park et al, ; Park et al, ; Van Hove et al, ).…”

“…Titanium nitride (TiN) and titanium niobium nitride (TiNbN) coatings have been used in arthroplasty since the 1980s because of their hardness and good tribological properties (Bone & Naylor, ; Breugem, Linnartz, Sierevelt, Bruijn, & Driessen, ; Buechel, Pappas, & Helbig, ; Buechel Sr, Buechel Jr, Helbig, D'Alessio, & Pappas, ; Buechel Sr, Buechel Jr, & Pappas Jr, ; Fabry, Zietz, Baumann, Ehall, & Bader, ; Harman, Banks, & Hodge, ; Hirschmann, Helfrich, & Friederich, ; Łapaj, Markuszewski, Wendland, Mróz, & Wierusz‐Kozłowska, ; Łapaj, Wendland, Markuszewski, Mróz, & Wiśsniewski, ; Mohammed, Metcalfe, & Woodnutt, ; Pappas, Makris, & Buechel, ; Park, Kang, Bae, & Song, ; Park, Kim, & In, ; Raimondi & Pietrabissa, ; Saxler, Temmen, & Bontemps, ). Their application is relatively inexpensive and can be easily performed in implants already used clinically without any major modifications of their design (Reich et al, ).…”

“…In such applications, the integrity and durability of the coating are of paramount importance, but despite a long history of clinical use, only a small number of studies regarding TiN coated total knee replacements (TKRs) are available (Breugem et al, ; Buechel et al, ; Fabry et al, ; Haider, Weisenburger, Croson, Namavar, & Garvin, ; Malikian, Maruthainar, Stammers, Wilding, & Blunn, ; Mohammed et al, ; Pappas et al, ; Park et al, ; Park et al, ; Saxler et al, ; Thienpont, ; Van Hove, Brohet, van Royen, & Nolte, ). Most of these papers demonstrated clinical results comparable to those of conventional TKRs, but very little is known about the durability of TiN coatings in vivo (Breugem et al, ; Fabry et al, ; Mohammed et al, ; Park et al, ; Saxler et al, ; Thienpont, ; Van Hove et al, ). The only retrieval analysis conducted so far used semiquantitative damage scoring and optical microscopy examination.…”

Survivorship and clinical outcome of the minimally invasive Uniglide medial fixed bearing, all-polyethylene tibia, unicompartmental knee arthroplasty at a mean follow-up of 7.3years

“…These may have advantages in reducing linear polyethylene wear and have been shown, in some studies, to be capable of producing good long term survivorship [11]. However bearing dislocation may occur in 1-5.3% of medial UKAs [12,13] and has been identified as the fourth most frequent mode of failure for mobile-bearing implants [14]. Fixed bearing designs have been shown in several studies to have equivalent clinical and radiographic outcomes compared to mobile-bearing implant designs at mid and long term follow up [15].…”

Hip and Knee Section, Treatment, Surgical Technique: Proceedings of International Consensus on Orthopedic Infections

“…Three studies successfully treated deep infection following UKA with retention of the implant with the first reporting 1 case treated with debridement and inlay exchange [34], the second reporting 2 cases treated with washout, debridement, and bearing/liner change [35], and the third reporting 1 case treated with synovectomy and placement of gentamicin chains [37].…”
