Modularity in total hip replacement(THR) enables precise recreation of native hip biomechanics. However, there have been concerns about raised metal ion levels with increased number of interfaces. We present the 3 year results of ML taper with Kinectiv technology(MLKT), a modular neck uncemented stem. This system has modular neck options, but has only one [0] head in various diameters. 97 hips in 97 patients with a MLKT stem and Continuum socket were included in this prospective study. Harris hip score, Oxford hip scores (HHS and OHS) and yearly blood Cobalt(Co), Chromium(Cr) and Titanium(Ti) were recorded. The primary end point was revision for any reason. Paired t- test was used to assess improvement in functional scores.Background
Methods
If and how closed valgus osteotomy of tibia is possible to influence intra and post operative results of total knee arthroplasty. Since 1985 to 2002 196 high tibial osteotomies were performed. 57 of them were treated by T.K.A. In 21 of 196 cases diagnostic arthoscopy performed for evaluation of the lesion. All osteotomies were closed wedge. Stabilization of the knee was done with plaster clast and in 50% of cases staples used. The time interval from osteotomy to T.K.A was 2–17 years mean 8 years. Follow-up of T.K.A. was 3–20 years. Scars, patella Baja, shortens of patellar tendon increased operative time and degree of difficulty. Postoperative results of T.K.A, were evaluated according the WOMAC (pain, stiffness, function) KSS (function) KSRIS (x-ray findings) were the same with those of primary T.K.A. Postoperative complications:
11 cases decrease in range of knee movment 3 fractures of external tibial condyle 2 mechanical loosening of T.K.A skin necrosis rupture of extension complex. Intaoperative difficulties in high valgus tibial osteotomy and afterrwords in T.K.A. were increased although postoperative results were the same. This is the reason that surgical experience is the target point of the result
