Aim of the present study is to investigate the influence of Body Mass Index (BMI) on compli-cations following THR in a single surgeon in the short term follow-up. Material and method: This study was based on the retrospective review of charts and BMIs from 171 patients who had undergone THR between April 2005 and March 2006 at our hospital. All operations were per-formed by a single surgeon. All patients were followed up 6 weeks after operation. Results: 27 / 171 patients (15.8%) were found to have com-plications. Systemic minor complications in-cluded arrythmia in 1 case, urinary tract infec-tion in two cases, ileus in two cases, renal in-sufficiency in 3 cases, confusion in 2 cases and anaemia in 14 cases (8.2%) requiring blood tr- ansfusion. There was one case of pulmonary embolism as a major systemic complication. Local minor complications included one single dislocation and 1 superficial wound infection. Body mass index ranged from 20.8 to 46.7 with a mean of 28.6. Hospital length of stay ranged from 10 to 42 days with a mean of 13. The leng- th of operation time between obese and non- obese patients varied significantly in our study. There was no increased risk for complications and length of hospital stay. Discussion: We can conclude that there are no economic or medical reasons for excluding obese patients from THR as there is no increased risk for complications and length of hospital stay.展开更多

The aim of our study was to show our experiences and mid-term results of TKA after a previous DFVO. Material and method: In a retrospective study we identified 36 consecutive patients who had undergone TKA after a previous distal femoral varus osteotomy. The average duration of follow-up after the TKA was 8.2 years (min: 5.0, max: 9.2). X-rays were taken in 2 planes before TKA, 1 week after TKA and at latest follow-up. Tibiofemoral alignment was measured on weightbearing long-leg anteroposterior radiographs. Ra- diolucent lines at latest follow-up were documented. Functional evaluations were performed preoperatively and postoperatively (at the time of latest follow-up). Results: The mean Knee Society knee score in- creased from 42 points before the arthroplasty to 91.3 points after the arthroplasty. The mean Knee Society function score increased from 27.4 points preoperatively to 93.2 points postoperatively. The mean overall Knee Society score increased from 91.3 points preoperatively to 163.4 points postoperatively. The mean radiographic alignment was 4.5? of valgus (10? of varus to 19? of valgus) before TKA and 3.1? of valgus (range, 3? of varus to 6? of valgus) at the time of latest follow-up. Postoperative complications included one deep vein thrombosis with non-lethal pulmonary embolism, one wound infection requiring revision and one septic loosening. Discussion: It is possible to perform TKA following DFVO with good mid-term results. In comparison to the literature there is no higher risk of complications in TKA following DFVO in comparison to primary TKA.展开更多
