Filter by:The mobile bearing unicompartmental knee arthroplasty has shown excellent clinical outcome and survivorship. However, some studies have shown that the patients still had medial knee pain and shown worst the clinical outcome, even though the survivorship was excellent. The medial knee pain after operation was the one cause of revision. The incidence of medial knee pain was 0%-9%. The cause of medial knee pain was overloading on the medial plateau, local inflammation, over hanging of the tibial component and overstretching of the MCL due to the application of excessive polyethylene. Therefore, the tibia in this study was cut with under resection technique for reducing the overloading on the medial tibial plateau. The purpose of this study is to compare medial knee pain between tibial bone cut preservation technique and conventional tibial bone cut technique following mobile bearing UKA.
Clinical studies on single-use ancillaries are still few; medico-economic benefits have to be assessed regarding their design and use. A foreseeable increase in the number of surgeries in the future, tends to change the techniques and consequently to question the medico-economic context. Single-use ancillaries attempt to provide solutions to today's imperatives and could be relevant from a global medico-economic point of view. For the moment, the conventional ancillaries for TKA are reused after sterilization. The objective of the study is to improve the fluidity of the intervention process with cost control.
The aim of the current project is to address a gap in the existing literature related to optimal placement of local anesthetic for an adductor canal (AC) block. The current study seeks to examine whether placement of the local anesthetic in the AC for knee surgery is more effective at reducing post-operative pain following arthroscopic knee surgery compared to a control. Specifically, if the anesthetic is more beneficial than the control group, the research will determine which location is optimal by comparing groups that receive anesthetic in the midpoint of the thigh, the proximal end of the thigh, or the distal end of the thigh.
Adductor canal block (ACB) is a peripheral nerve blockade technique that provides good pain control in patients undergoing total knee arthroplasty (TKA) which however does not relieve posterior knee pain. The recent technique of an ultrasound-guided local anesthetic infiltration of the interspace between popliteal artery and the capsule of posterior knee (IPACK) has shown promising results in providing significant posterior knee analgesia without affecting the motor nerves. The hypothesis was that the combination of ACB + IPACK will provide better pain relief and improve knee function in the immediate postoperative period compared to ACB alone.
The primary objective of this study is to compare effect of combined block of ACB (adductor canal block) with IPACK (Interspace between the Popliteal Artery and the Capsule of the posterior Knee) block and/or Intra-articular block in immediate postoperative and early postop rehabilitation and pain management in patients undergoing primary TKA. The secondary objective is to review both in-hospital and post-discharge pain levels and narcotic usage of primary TKAs, with a minimum 6-week postoperative follow-up.
Vitamin D status has been shown to have an effect on post-operative outcomes in total joint arthroplasty. The goal of this study is to determine if pre-operative supplementation and correction of Vitamin D deficiency can reduce postoperative complications.
Femoral nerve catheter for postoperative analgesia will be included in the adult patients undergoing total knee arthroplasty included in the study. These patients will be randomized to the catheter tip configuration as CEMP (closed-ended multiport catheter) group and OESP (open-ended single port catheter) group. Patient controlled analgesia device will be attached to the peripheral nerve catheter of these patients. Demographic data of the patients , the number of pushing the button the amount of bolus dose given, and the total dose given in the patient controlled anesthesia device, the need for additional analgesia and the amount, pain scores, complications will be recorded for three days postoperatively. Records will be compared statistically.
The ultrasound-guided selective blockade of the saphenous nerve in the adductor canal provides effective analgesia and reduces postoperative pain in patients undergoing arthroscopic medial meniscectomy. Selective blockade of the saphenous nerve in the adductor canal provides effective analgesia without quadriceps muscle weakness. It has been shown that the adductor canal block (ACB) block increases the spread of local anesthetics in a distal and proximal way. Therefore, the proximal spread of local anesthetics may cause possible quadriceps weakness. The distal spread of local anesthetics may increase analgesic effect via sciatic nerve. The different volumes for ACB is a topic of discussion. The aim of this study is to compare the different volumes of US-guided ACB performing for postoperative analgesia management after total knee arthroplasty surgery.
Total knee arthroplasty(TKA) is a successful orthopedic surgery with excellent clinical outcome and survival. However, there are concerns about patient satisfaction in previous reports, and dissatisfaction rate of 15-30% is reported in clinical outcomes(PROMs) of some studies. Therefore, for improving the patient's outcome and satisfaction after total knee arthroplasty, it is necessary to change the design of the conventional total knee arthroplsaty implant. The knee is a joint structure with several dynamic functions, and not only the skeletal structure but also the soft tissue balance plays an important role in the function of the knee joint. New implants are being developed to overcome the limitations of conventional TKA implant, including the Journey II Bi-cruciate substituting total knee system (JII-BCS; Smith & Nephew). JII-BCS implant has normal articular geometry, more anatomical femoral shape, lateral tibial convex geometry, and asymmetrical tibial plateau, anterior and posterior cams, which has been shown in experimental studies to produce nearly normal knee movement by reproducing the actual normal anatomical alignment in vivo. The clinical results of the kinematic effects of this anatomcally aligned change are insufficient, and there is also a lack of comparative studies with conventional total knee arthroplasty implant. The purpose of this study is to compare outcomes between anatomically aligned TKA(JII-BCS) and conventional TKA(Legion total knee system, Smith & Nephew). This study is a randomized controlled study in patients undergoing same-day bilateral total knee arthroplasty. A patient undergoing same-day bilateral total knee arthroplasty will use a random number to determine the instruments(JII-BCS or Legion), and both knee joints will be operated with the same instruments. Radiologic parameter, patients preference and clinical results was investigated in patients who received TKA during minimum 2 year follow up.

Design Randomized controlled trial. Setting Rehabilitation structure, inpatient Main outcome measures Pain subscale of the WOMAC and Lequesne's Algo-Functional Index (LIKERT scale), knee circumference (measured at the middle line of the knee joint space) and knee flexion /extension range of motion by goniometer.
