Synopsis: 591 patients scheduled to undergo major orthopedic surgery were randomized to receive either sublingual sufentanil or intravenous patient-controlled morphine for postoperative analgesia. This was done to assess the onset of action of a sufentanil sublingual tablet system compared to that of intravenous patient-controlled analgesic morphine. Pain intensity and Read More »
Conference Report
Synopsis: 18 patients with adult flexible flatfoot deformity scheduled to undergo surgical treatment were randomized to receive either lateral column lengthening or subtalar arthroereisis. The purpose of this study was to compare the efficacy of the two procedures in terms of radiological and clinical results. Radiographs, AOFAS Midfoot Read More »
Conference Report
Synopsis: 82 knees of patients undergoing total knee arthroplasty (TKA) were randomized to either receive a deep intra-articular drain or not. The purpose of this study was to compare the two approaches based on complications and early knee functional outcomes. Patients in the Read More »
Conference Report
Synopsis: This trial conducted randomized sub-studies on patients undergoing total knee arthroplasty with a pneumatic tourniquet. The first study randomized 160 patients to the use of either low (SBP + 120 mmHg) or high (SBP + 150 mmHg) tourniquet pressures with the purpose of quantifying an effective and safe tourniquet pressure. Following the intraoperative Read More »
Conference Report
Synopsis: 18 patients (28 hips) with osteonecrosis of the femoral head (ONFH) were randomized to receive core decompression with or without a concentrated bone marrow injection. The aim of this study was to compare the aforementioned treatments, in order to determine the effects of stem cell augmentation on ONFH. Patients were assessed Read More »
Conference Report
Synopsis: 30 orthopaedic trainees were included in this randomized trial investigating the effect of simulation-based training on ankle arthroscopy performance. Following baseline simulation-arthroscopy and cadaveric diagnositc arthroscopy, participants were randomized to either four sessions of ankle arthroscopy simulator training, or to standard arthroscopic exposure. Performance evaluation was Read More »
Conference Report
Synopsis: 80 patients scheduled for minimally invasive total knee arthroplasty (MIS-TKA) were randomized to undergo the procedure with the use of a new hand-held navigation device (iAssist group) or not. The purpose of the study was to compare radiographic outcomes of alignment and positioning of the prosthesis, as well as surgical outcomes (operative time, bone cutting time, blood loss). The results of Read More »
Conference Report
Synopsis: 49 patients who underwent open reduction internal fixation for tibial plateau fractures were randomized to receive bracing for 6 weeks or no bracing following the procedure. The purpose of this study was to compare functional, subjective, and radiographic outcomes of brace use to no bracing after ORIF of tibial plateau fractures. Results indicated no Read More »
Conference Report
Synopsis: 128 patients with knee cartilage defect were randomized to compare the efficacy and safety of matrix-induced autologous chondrocyte implantation (MACI implant) and microfracture (MFX) surgery. Primary outcomes were mean improvement Knee Injury and Osteoarthritis Outcome Scores (KOOS) Pain and Function subscales, and secondary outcomes were mean improvement in KOOS ADL, knee-related QoL, and other symptoms subscales, response rate (>10-pt improvement in KOOS Pain and Function score), Modified Cincinnati Knee Rating System, IKDC Subjective Knee Evaluation Overall Score, and failure rate (surgical re-treatment due to treatment response failure). After 3 years, Read More »
Conference Report
Synopsis: 390 patients with chondral knee defects and previously failed surgery were randomized to undergo either autologous chondrocyte implantation (ACI) or an alternative standard repair procedure (ie. microfracture, autologous matrix-induced chrondrogenesis, mosaicplasty, debridement), with the choice of standard treatment left to the patient and surgeon. The purpose of this study was to determine if ACI conferred a significant functional benefit when compared to standard chondral repair procedures over the long-term. Primary outcomes were Read More »
Conference Report
Synopsis: 50 patients undergoing unilateral total knee arthroplasty without a pneumatic tourniquet were randomized to receive tranexamic acid (TXA) perioperatively or placebo. The purpose of this study was to evaluate the safety and efficacy of TXA in patients being operated without a tourniquet, as compared to a placebo-controlled group. Total blood loss, Read More »
Conference Report
Synopsis: 45 orthopaedic residents were invited to participate in this study evaluating improvement in knee arthroplasty performance, and were randomized to either cadaveric training, a virtual reality simulation, or no training. The aim of this study was to determine the efficacy of each training modality in improving knee arthroscopy performance among residents, and to assess the cost-effectiveness of each method. Video recordings were Read More »
