Effect of intraoperative cold solution irrigation to reduce postoperative pain in knee osteoarthritis patients who underwent unilateral primary total knee arthroplasty: a double-blinded randomized controlled trial.

Purpose: To compare the postoperative pain score, opioid consumption, and blood loss in knee osteoarthritis patients who underwent unilateral primary total knee arthroplasty with and without intraoperative cold solution irrigation.

Method: In total, 70 knee osteoarthritis patients were randomly included in the study and allocated into 2 groups. The first group was irrigated intraoperatively with a cold solution and the second group was irrigated intraoperatively with a room-temperature solution.

No association between different in tibial resection level and clinical outcomes six months after Oxford unicompartmental knee arthroplasty: a prospective cohort study.

Background: Localized tibial strain is one of the hypotheses to explain residual pain after Oxford UKA. We evaluate whether the depth of the vertical cut during tibial resection correlates with medial knee pain. We aimed to investigate the association between the depth of tibial resection and medial knee pain after OUKA.

No Effect of Oral Mecobalamin on Skin Numbness at 3 Months After Total Knee Arthroplasty: A Randomized, Double-Blinded, Placebo-Controlled Superiority Trial.

Background: An area of skin numbness (AON) around an incision commonly occurs following total knee arthroplasty (TKA). Mecobalamin has been shown to facilitate peripheral nerve recovery in various conditions; accordingly, the present study aimed to investigate the ameliorative effect of mecobalamin on AON following TKA, as compared with a placebo.

Methods: This superiority study was a double-blinded, randomized controlled trial.

Blood loss and transfusion rate compared among different dosing regimens of tranexamic acid administration in patients undergoing hip hemiarthroplasty for femoral neck fracture: A randomized controlled trial.

Background: Intravenous tranexamic acid (TXA) administration is a proven safe and effective method for reducing both blood loss and transfusion in total joint arthroplasty. However, data specific to its efficacy in hip hemiarthroplasty (HHA) for femoral neck fracture are scarce. Furthermore, no study has investigated the efficacy of an additional dose of TXA administration.

Cosmetic outcomes and patient satisfaction compared between staples and subcuticular suture technique for wound closure after primary total knee arthroplasty: a randomized controlled trial.

Introduction: Staples and subcuticular suture are commonly used wound closure techniques after total knee arthroplasty (TKA). To date, only a few studies have investigated the differences between these two wound closure methods in TKA. Accordingly, this study aimed to compare cosmetic outcome and patient satisfaction between staples and subcuticular suture for post-TKA wound closure.

Heterotopic ossification after closed femoral nailing.

Background: Heterotopic ossification is defined as pathological bone formation in soft tissue, it usually occurs postoperatively and varies in amount from faint to massive ossification, which are frequently asymptomatic. The cause of heterotopic ossification is unknown, but it occurs more commonly after the procedure, in which considerable bone and soft tissue are dissected extensively. The heterotopic ossification in the abductor region of the hip following closed femoral nailing has rarely been documented.

A randomized control trial between fosfomycin and cefuroxime as the antibiotic prophylaxis in knee arthroplasty.

Background: Antibiotic prophylaxis is used in all patient underwent total knee arthroplasty to prevent post operative infection which produced poor outcome. The suitable drug should be safe and good efficacy.

Objective: To study safety and efficacy of fosfomicin and cefuroxime as antibiotic prophylaxis for total knee arthroplasty.

Cementless hemispheric porous-coated sockets implanted with press-fit technique without screws: average ten-year follow-up.

Background: Press-fit implantation of a porous-coated hemispheric acetabular component without screws is an option for primary total hip replacement. The purpose of the present study was to evaluate the results of this technique after an average duration of follow-up of ten years to determine if there was any loss of fixation or increase in osteolysis over time.

Methods: From June 1988 to November 1990, 132 primary total hip replacements were performed with a porous-coated socket that was implanted with use of a press-fit technique.

Jumbo femoral head for the treatment of recurrent dislocation following total hip replacement.

Background: The purpose of this study was to assess the results of the use of a jumbo femoral head to restore stability in hips that had sustained recurrent dislocations after total hip replacement.

Methods: Twelve hips in twelve patients who had had multiple hip operations and recurrent instability of the hip underwent a total hip replacement with use of a femoral head with an average diameter of 44 mm (range, 40 to 50 mm). The average age of the patients was fifty-nine years (range, twenty-nine to eighty-four years).

Intraoperative monitoring for safety of bilateral total knee replacement.

Cardiopulmonary hemodynamics in 79 consecutive patients who had one-stage bilateral total knee replacements were monitored prospectively with a pulmonary artery catheter. The pulmonary vascular resistance, wedge pressure, pulmonary artery pressure, and systemic vascular resistance were measured before skin incision, 5 to 10 minutes after implanting the first total knee replacement, and after the second knee replacement. The second knee replacement was cancelled in five patients because the pulmonary vascular resistance after the first knee replacement was more than double the baseline, or above 200 dyne/second/cm(5).
