To evaluate the effectiveness of post-operative pain management using the intra-operative peri-articular injection(PAI) and/or electromyography (EMG)-guided preoperative femoral nerve block (FNB) in total knee arthroplasty(TKA). From March 2013 to February 2014, 90 knees which underwent primary TKA by one surgeon were included in our study. The patients were classified into three groups; a single injection FNB with an EMG guide (Group I, 30 knees), intra-operative PAI (Group II, 30 knees) and both FNB and PAI (Group III, 30 knees). Pain at rest and moving was evaluated by Visual Analogue Scale (VAS) at postoperative 0, 4, 8, 24 and 48 hours. Postoperative range of motion, time to walking, total blood loss, amount of opioid consumption and complications were compared in each group.Purpose
Materials and Methods
To measure the vitamin D level of the patients who received total knee arthroplasty (TKA) and evaluate the effect of vitamin D level on the results of TKA. From February 2012 to January 2013, 151 female patients (204 knees) who underwent primary TKA by one surgeon were included in our study. Preoperative vitamin D level was measured and analyzed the relationship between that and preoperative Visual Analogue Scale (VAS), and Knee Society Knee Score (KS) and Function Score (FS). Thirty-nine patients (39 knees) who received unilateral TKA and could be followed up more than 1 year after operation were evaluated for the relationship between vitamin D level and postoperative VAS, KS and FS, and Western Ontario and McMaster Universities Arthritis Index (WOMAC) score.Purpose
Materials and Methods
The NexGen® legacy posterior stabilized (LPS)-Flex total knee system (Zimmer, Warsaw, IN) is designed to provide 150° of flexion following total knee arthroplasty (TKA). But, recent reports found a high incidence of loosening of the femoral component related to the deep flexion provided. We evaluated 9- to 12-year clinical and radiological follow-up results after NexGen® LPS-Flex TKA. A retrospective evaluation was undertaken of 209 knees in 160 patients (21 males, 139 females) who were followed up for more than 9 years after Nexgen®LPS-Flex TKA. Evaluations included preoperative and postoperative range of motion(ROM), Knee Society(KS) knee score, function scores, tibiofemoral angle and assessment of postoperative complications.Purpose
Materials and Methods
The purpose of this study was to compare the clinical and radiological results after total knee arthroplasty(TKA) with PCL sacrificing (PCS) Medial Pivot Knee (MPK) and PCL Substituting (PS) Nexgen® LPS. One hundred twenty knees in 80 patients after TKA with PCS ADVANCE® MPK (Group I) and 116 knees in 85 patients with PS Nexgen® LPS (Group II) were retrospectively evaluated. All the patients were followed up for more than 6 years. The evaluations included preoperative and postoperative range of motion (ROM), tibiofemoral angle, Knee Society (KS) knee and function score, Hospital for Special Surgery (HSS) knee score, WOMAC score and postoperative complications.Purpose
