“…The main factor limiting long-term THA survival is wear debris production from bearing surfaces ( 4 ). Femoral head wear has so far been described only in revision surgery with metal-on-polyethylene bearing after a primary ceramic-on-ceramic THA, when it was caused by ceramic particles embedded in the acetabular liner ( 3 ).…”

Excessive metal femoral head wear has been described only as revision surgery complication after primary ceramic-on-ceramic total hip arthroplasty (THA). Here, we present the first case of metal femoral head wear after primary metal-on-polyethylene THA. A 56-year-old woman was referred to our outpatient clinic 17 years after primary right-sided THA, experiencing pain and decreased right hip range of motion. Radiographic examination revealed acetabular cup dislocation, eccentric femoral head wear, damaged titanium porous coating of femoral stem, metallosis, and pseudotumor formation. Endoprosthetic components were extracted, but further reconstruction was impossible due to presence of large acetabular bone defect. Macro- and micro-structure of extracted components were analyzed. Acetabular liner surface was damaged, with scratches, indentations, and embedded metal debris particles present on the entire inner surface. Analysis of metal debris by energy-dispersive spectroscopy showed that it consisted of titanium and stainless-steel particles. Femoral head was gravely worn and elliptically shaped, with abrasive wear visible under scanning electron microscope. No signs of trunnionosis at head/neck junction were observed. Microstructure of femoral head material was homogeneous austenitic, with microhardness of 145 HV 0.2, which is lower than previously described titanium hardness. In conclusion, detached titanium porous coating of femoral stem can cause stainless-steel femoral head wear in primary metal-on-polyethylene THA. As soon as such detachment becomes evident, revision surgery should be considered to prevent devastating complications.

“…8 Most common agent of peri-prosthetic infection is Staphylococcus aureus, followed by coagulasenegative Staphylococcus and Streptococcus for total knee replacement. 1,3,9 Delayed infections may present with subtler symptoms which are for example joint pain and early loosening. These are caused by low-virulent organisms (coagulase-negative staphylococci or Cutibacterium species).…”

Hem diz ve hem de kalça artroplastileri, ortopedinin oldukta başarılı ameliyatlarıdır. Mükemmel ve uzun yaşam sonuçları vardır. Artan ameliyat sayılarına ve başarı oranlarına rağmen, genel ve ciddi komplikasyonları da artış göstermektedir. Literatürden yaptığımız derlemede, kalça ve diz artroplastilerinin yaygın komplikasyonları olan enfeksiyon, dislokasyon, periprostatik kırıklar, septik gevşeme ve ven tromboembolisini taradık. Bu komplikasyonlar çok dramatik problemlere neden olabilmekte ve dikkatli tedavi gerekmektedir. Bu komplikasyonları minimuma indirgemek icin gerekenler, kendini geliştirmiş tecrübeli ortopedik cerrahlar ve konusunda özelleşmiş, uygun çevresel ortama sahip bir takım ve uygunluğu ispatlanmış protezlerin kullanılmasıdır.

Aseptic loosening of a permanent prosthesis remains one of the most common reasons for bone implant failure. To improve the fixation between implant and bone tissue as well as enhance blood vessel formation, bioactive agents are incorporated into the surface of the biomaterial. This study reviews and compares five bioactive elements (copper, magnesium, silicon, strontium, and zinc) with respect to their effect on the angiogenic behavior of endothelial cells (ECs) when incorporated on the surface of biomaterials. Moreover, it provides an overview of the state-of-the-art methodologies used for the in vitro assessment of the angiogenic properties of these elements. Two databases are searched using keywords containing ECs and copper, magnesium, silicon, strontium, and zinc. After applying the defined inclusion and exclusion criteria, 59 articles are retained for the final assessment. An overview of the angiogenic properties of five bioactive elements and the methods used for assessment of their in vitro angiogenic potential is presented. The findings show that silicon and strontium can effectively enhance osseointegration through the simultaneous promotion of both angiogenesis and osteogenesis. Therefore, their integration onto the surface of biomaterials can ultimately decrease the incidence of implant failure due to aseptic loosening.
