A proper restoration of hip biomechanics is fundamental to achieve satisfactory outcomes after total hip arthroplasty (THA). A global hip offset (GO) postoperatively reduction of more than 5 mm was known to impair hip functionality after THA. This study aimed to verify the restoration of the GO radiographic parameter after primary THA by the use of a cementless femoral stem available in three different offset options without length changing. From a consecutive series of 201 patients (201 hips) underwent primary cementless THA in our centre with a minimum 3-year follow up, 80 patients (80 hips) were available for complete radiographic evaluation for GO and limb length (LL) and clinical evaluation with Harris hip score (HHS). All patients received the same femoral stem with three different offset options (option A with – 5 mm offset, option B and option C with + 5 mm offset, constant for each sizes) without changing stem length.Introduction and Objective

Difficult primary total knee arthroplasty (TKA) and revision TKA are high demanding procedures. Joint exposure is the first issue to face off, in order to achieve a good result. Aim of this study is to evaluate the clinical and radiological outcomes of a series of patients, who underwent TKA and revision TKA, where tibial tubercle osteotomy (TTO) was performed. We retrospectively reviewed a cohort of 79 consecutives TKAs where TTO was performed, from our Institution registry. Patients were assessed clinically and radiographically at their last follow-up (mean, 7.4 ± 3.7 years). Clinical evaluation included the Knee Society Score (KSS), the pain visual analogue scale (VAS), and range of motion. Radiological assessment included the evaluation of radiolucent lines, osteolysis, cortical bone hypertrophy, time of bone healing of the TTO fragment, and the hardware complication.Introduction and Objective

The experience that we gathered using uncemented stems for revisions with diaphyseal anchorage gave us satisfactory outcomes both for survival curve (94% of cases – 15 yrs follow-up) and for clinical results in the aseptic mobilisations. Thus, we extended this technique in the re-implant of septic prostheses. We treated 43 cases of septic hip prostheses from 2003 to 2006. The treatment of choice has been the two-stage revision with the implant of temporary spacer, utilising the one-stage treatment just in few cases selected from needle-aspiration positive culture. The technique foresees the utilisation of Wagner uncemented revision stems in 98% of cases and 2% using a first implant prosthesis. Accompaniment antibiotic protocol has been protracted for 3 – 6 months till the negativity of the inflammation index. Average follow-up of 26 months shows good clinical and radiographical results with percentage of a new revision of the two-stage in 2.32% (1 case). The uncemented components are confirmed to be the best presidia for the implant stability retrieval in the immediate and long-term either, the two-stage strategy appears sure enough for the re-infections control especially associated with an adequate antibiotic treatment. Therefore, the choice strategy proposed by us favours the uncemented implants in combination with the two-stage.
Clinical evaluations show an average score of 78 (acc. to HHS); 82,3 percent of patients are pain free, while slight pain still persists in a 13,7 percent pain in a 3,9 percent. The radiographic analysis has put into evidence only 1 case of mobilization, and suffering bone in 4 percent of cases; by contrast, 79,5 percent show astonishing endosteal bone formation.
