95 years). A total of 28 RP and 19 FB knees (58.8%) were analyzed at the final follow-up. Results Among all patients, KSS and WOMAC scores statistically improved from pre-op to 2-year, while KSS statistically worsened from 2-year to final follow-up. The RP group averaged better follow-up scores in all assessments at the final follow-up with exception of overall satisfaction. There was no statistically significant difference in the functional Knee Society Score, Short Form-36, WOMAC scores, patient satisfaction or implant survival between the two groups at any measured period. Conclusions The use of a fixed-bearing or rotating-platform design does not convey significant superiority in terms of function or implant longevity at a minimum twelve years after total knee arthroplasty. Level of evidence Level I, Experimental study, randomized controlled trial (RCT). © 2019.Objectives Though the role of chronic kidney disease (CKD) has been studied previously in primary arthroplasty procedures of the hips and knees, there is a paucity of literature analyzing CKD's impact on surgical outcomes in revision total knee arthroplasty (rTKA) patients. As the number of patients with CKD requiring revision surgery increases, more vigilant pre-operative and post-operative measures can be taken to ensure successful outcomes. This retrospective study sought to 1) determine differences in demographics and preoperative comorbidities of patients with normal or mild CKD and those with moderate/severe CKD and 2) establish moderate/severe CKD as an independent risk factor for complications in the 30-day postoperative period in patients undergoing rTKA. Methods The ACS-NSQIP database was queried for patients who had undergone rTKA from 2005 to 2016. Patient were assigned to one of five CKD severity classes after eGFR calculation and were further stratified into two cohorts stages 1/2 vs. stages 3/4 healthcare professionals for better patient-optimization. Orthopaedic surgeons should factor in CKD severity in the management of patients undergoing rTKA to effectively mitigate the effects of adverse events. © 2019 Delhi Orthopedic Association. All rights reserved.Objectives Assessing the effects of diabetes mellitus (DM), non-insulin-dependent diabetes mellitus (NIDDM), and insulin-dependent diabetes mellitus (IDDM) on revision TKA (rTKA) has become increasingly imperative due to the increased rates of revisions associated with DM. This study sought to identify complications in rTKA that were independently associated with NIDDM/IDDM compared to non-diabetic (Non-DM) patients and whether IDDM was associated with specific postoperative complications compared to NIDDM. Methods and materials 16,428 rTKA patients were identified from the ACS-NSQIP database from 2005 to 2016 and stratified into three separate cohorts. 12,922 (78.66%) were Non-DM, 2335 (14.21%) had NIDDM, and 1171 (7.13%) had IDDM. Univariate analyses were utilized to assess for differences in demographics, preoperative comorbidities, and postoperative complication rates. Multivariate logistic regression analyses were then employed to control for significant differences in patients characteristics to assess diabetes patients further divided based on insulin dependence status were also noted. Future work examining whether targeting perioperative glucose levels less then 200 mg/dL in DM rTKA patients decreases infectious complications is warranted. Future work analyzing the role of tranexamic acid administration and 24-h postoperative antibiotics in rTKA IDDM patients may be warranted given the elevated risk of pneumonia, septic shock, and blood transfusions. © 2019 Delhi Orthopedic Association. All rights reserved.Background Total Knee Arthroplasty (TKA) is one of the most effective treatment modalities for chronic knee pain and disability. A strong association exists between obesity and early knee osteoarthritis. Various studies on outcomes of TKA in obese patients have been inconclusive. The purpose of this retrospective evaluation is to assess the influence of obesity on outcomes of TKA in Indian patients. Methods This retrospective study conducted from 2010 to 2016 included 402 knees in 213 patients with Body Mass Index (BMI) between 30 and 39.99 kg/m2 followed up for a minimum of 12 months. All cases of revision TKAs and those with follow up less than a year were excluded from the study. Patients were followed up regularly for examining their wound healing, post operative complications if any and knee range of motion. Regular radiographs were taken to observe any evidence of loosening. Post-operative knee society scores(KSS) were recorded at each follow up. Improvement in the scores and activity level was noted. Results The objective KSS improved from 55.88 to 93.01 at the last follow up while the functional scores improved from 52.91 to 80.63. Post surgery improvement in activity level was seen in 71.83% patients. Complications seen in the study included patello-femoral pain, superficial wound infections, deep vein thrombosis and delayed wound healing. No cases of deep infection or revision surgeries were seen in our series. Conclusions The outcome of TKA in non-morbidly obese patients is comparable to non-obese patients with excellent post-operative objective and functional scores. The benefits are sustainable over a long duration of time. The complication rates in obese patients is no different than non-obese patients. © 2018 Delhi Orthopedic Association.

In this retrospective study, we compared whether clamped or unclamped drainage has any advantages over the other in unilateral TKA. Methods Group-A (n = 351) had an unclamped drain removed at 24 h postoperative, with measurement of total drainage at 24 h between January 2011 and February 2013. Group B (n = 349) had drains kept for a total of 8 h-clamped for the first 4 h and unclamped for a further 4, between March 2013 to September 2016. Drainage volume, as well as the hemodynamic markers-hemoglobin (Hb) drop, transfusion rate were evaluated. Results Mean drain output in Group- A was significantly higher than Group- B (215.64 ml versus 28.34 ml). The postoperative Hb was significantly higher in Group-B (11.46 g/dl versus 10.57 g/dl). Mean Hb drop was significantly higher in Group A (2.16 g/dl versus 1.18 g/dl). https://www.selleckchem.com/products/kpt-330.html The transfusion rates were lower in Group-B, though not statistically significant.
