Primary total knee replacement (TKR) is a known world-wide standard and definitive treatment of primary knee OA following failed adequate non-operative management. It is of clinical importance to assess the clinical and functional outcome of TKR to prognosticate the severity of primary knee OA. The new (2011) knee society scoring system (nKSS) is both surgeons and patients’ assessment tool for the treatment outcome of TKR. Study Design: Prospective interventional analytical study. Aim and Objective: The aim of the study was to determine early clinical and functional outcome of primary total knee replacement in patients with primary knee osteoarthritis using nKSS. The objectives were: 1) To determine the pre-operative nKSS and post operative nKSS;2) To determine relationships between pre-operative nKSS and post operative nKSS at 6 weeks, 3, 6, 9 and 12 months;3) To determine the complication rates in patients undergoing primary TKR in the study centre. Methods: A prospective interventional study of 59 patients aged 51 to 70 years who had 67 Total Knee Replacements (TKRs) participated in the study between November 2015 to June 2018 at National Orthopaedics Hospital, Lagos, Nigeria. Patients’ sociodemographic data, pre-operative and post-operative nKSS system were recorded at 6 weeks, 3, 6, 9 and 12 months during follow up. The data were analyzed using Statistical Package for Social Science (SPSS). Results: There were 41 females and 18 males (M:F = 1:2.3). There were total of 67 TKRs with 31 right TKRs, 20 left TKRs and 8 staged bilateral TKRs. The participants’ age ranged from 51 to 70 years with the mean age of 59.5 (±8.5) years. Four patients did not complete the study due to various reasons. The remaining 55 participants completed the study period with progressive improvement of their post-operative nKSS at 6 weeks, 3, 6, 9 and 12 months post-operatively when compared with pre-operative nKSS (P value 0.5). Conclusion: This study revealed improved early clinical and functional outcome of primary total knee replacement in primary knee osteoarthritis using nKSS in all the studied patients. There is no significant negative effect of lower pre-operative nKSS (and its components) on the post-operative nKSS outcome.展开更多

Now the construction of a well-off society in an all-round way enters a critical stage, so the original evaluation standards must change with gradual advancement of the construction goal of a well-off society. So it is very necessary for us to build a comprehensive evaluation index system and make it better and better to provide effective statistical consultation and statistical supervision for constructing a well-off society in an all-round way. This paper attempts to analyze the current evaluation index system, then puts forward the general thinking and flame work of the index system of building a well-off society in an all-round way.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
