“…Few systems however present the features of a "full" non allergenic implant; they are characterized by an oxidized zirconium femoral component articulating with an all-polyethylene tibial component, implants with zirconium nitride femoral and tibial components, and systems with a ceramic femoral component. Encouraging outcomes comparable with standard Cr-Co alloys implants have been reported with a short to mid-term follow-up [19][20][21][22].…”

Purpose We evaluated the risk of hypersensitivity to metals in a population of consecutive subjects undergoing a total knee arthroplasty (TKA). We also proposed a diagnostic pathway to address any sensitivity to metals. We finally presented the mid-term outcomes of a full non allergenic knee implant. Methods We developed a protocol based on the medical history, patch testing, and on specific laboratory assays, in order to assess a sensitization to metals. Twenty-four patients (25 knees) with referred or suspected allergy to metals were found in more than 1,000 treated patients, with a mean age of 72.9 years. We proceeded to a radiologic study, a clinical evaluation by the visual analogic scale (VAS), and Knee Society rating system (KSS). In all cases a full anallergic cemented implant with an oxidized zirconium femoral component and an all-polyethylene tibial baseplate was chosen. Results Four (16.6%) of the 24 patients were considered to be hypersensitive to metals. The mean follow-up was 79.2 months. No patient reported any reaction related to hypersensitivity or complications after TKA. The VAS improved from a mean preoperative value of 7.2 to 1.8 postoperatively; the KSS and the functional score increased from 38 to 91 points and from 39 to 88 points, respectively. Conclusions We consider careful research of medical history for metals hypersensitivity crucial, and we perform patch testing and lab assays in case of doubtful sensitization. The choice of a modern hypoallergenic implant may prevent any kind of potential reactions.

Total knee arthroplasty following complex fractures of the tibial plateau is considered a challenge for orthopaedic surgeons and clinical outcomes may vary. A total of 29 total knee replacements were performed after a tibial plateau fracture: 25 patients (16 women, 9 men; average age: 57 years; mean follow-up: 92 months) were available. We had two significative complications: one partial avulsion of the patellar tendon, conservatively treated by bracing, and one case of deep venous thromboembolism, managed with low molecular weight heparin. In two cases (8%) there was a failure of the implant; nine cases were excellent, nine good, four fair and one poor. A percentage of patients with previous complex proximal tibia fractures had an increased rate of postoperative complications due to anatomical deformity, functional deficiency and post-traumatic arthritis and required solutions similar to revision surgery. Total knee arthroplasty is a suitable solution for the treatment of these challenging cases: compared to primary knee replacement, final KSS score is generally lower, but improvement is similar due to poorer pre-operative scores.
