Knee Arthritis

The purpose of this study is to see if cannabidiol (CBD) orally dissolving tablets (ODTs) can lessen pain, improve function, and improve patient satisfaction in cases of knee osteoarthritis. CBD comes from the cannabis plant and is non-psychoactive (i.e. does not produce a 'high' or altered mental state) as compared to tetrahydrocannabinol (THC), another compound found in cannabis. Researchers are studying different forms of CBD for potential use in treating pain, inflammation, and illnesses.

This study is a prospective, single-arm interventional trial enrolling patients undergoing total knee arthroplasty (TKA) for knee arthritis. All participants will receive Suzetrigine (brand name Journavx by Vertex Pharma) as part of a standardized multimodal perioperative analgesic regimen in addition to standard of care.

A prospective, multi-center, double-arm, parallel, interventional, randomized, controlled clinical trial to assess the rate of periprosthetic joint infection (PJI) in patients undergoing primary total knee arthroplasty (TKA), total hip arthroplasty (THA) or hip resurfacing (HR) with XPERIENCE™ (XP) Advanced Surgical Irrigation versus dilute Betadine (DB).

The ARC Study is a national observational cohort study to investigate patient reported and clinical outcomes after hip and knee replacements. The study has the following objectives: 1. To evaluate outcomes following hip and knee replacements. 2. To determine risk factors for adverse outcomes in primary hip and knee replacements. 3. To identify targets for future research and intervention in patients undergoing primary hip and knee replacements 4. To provide a resource from which to identify potential participants for future clinical trials, and to use data collected in the ARC Study as comparison or control data for trial participants who have been randomised to receive one or more interventions. Participants are recruited and consented online. Patients are invited to participate by collaborating surgical teams nationally in outpatient clinics at the time of being added to a waiting list, in addition to an advertising campaign to recruit patients. They are directed to an online portal where they will be able to review further information. Consent and data collection is completed electronically through patients entering data online. Baseline demographics and characteristics are recorded, including details of socio-demographics, lifestyle, health status and patient reported outcome measures (PROMs). Patients then undergo hip/knee replacement and postoperative rehabilitation according to the standard care and protocols of the hospital and the preferences of their treating surgeon. Follow-up data, including PROMs, is collected via online questionnaires up to two years following surgery. The study will ultimately also enable multiple trials to be embedded within the cohort study, using a 'Trials within Cohorts' (TwiCs) methodology.

The purpose of this study was to investigate the effect of bupivacaine liposomes on postoperative pain in TKA ( total knee replacement ) patients.The main questions answered are: 1. Is bupivacaine liposomes superior to bupivacaine in femoral triangle block or adductor block in terms of 72 hours opioid consumption after knee replacement 2. Which block method(Femoral triangle block or adductor block) combined with bupivacaine liposome was more effective in alleviating pain score and 72 hours opioid consumption after total knee surgery. investigators will investigate the effect of bupivacaine liposomes combined with bupivacaine and pure bupivacaine on pain after total knee arthroplasty using femoral triangle block or adductor block. Participants will: 1. Receive liposomal bupivacaine or bupivacaine as a regional anesthetic for femoral triangle block or adductor block under ultrasound guidance. 2. Undergo total knee replacement surgery under spinal anesthesia. 3. Follow-up within 72 hours after surgery , opioid consumption, NRS score, PCA（Patient controlled analgesia，PCA） data, first postoperative remedial analgesia time, quadriceps muscle strength and complications were recorded

Patients will be prospectively recruited for knee joint distraction who are undergoing knee arthroscopy. Patient demographics, operative factors, and rates of medical comorbidities will be collected and evaluated. Intraoperative arthroscopic images will be evaluated by the attending Orthopaedic surgeon with standard and testing mechanism and a measuring device will be used to measure the distance between the femur and tibia in the medial and lateral compartments.

The goal of this prospective study is to compare two different knee replacement robots. This study will look at patient reported outcome measures and data collected during the operation. The main questions this study aims to answer include: * Will the patient reported outcomes differ between the two groups? * Will the intraoperative data differ between the two groups? Participants will undergo total knee replacement with one of the two robots, complete standardized surveys, and have x-rays taken.

This clinical trial is conducted to assess the long-term safety of "jointstem" in patients with degenerative knee arthritis who participated in the previous BS-JS-IIT1 investigator initiated trial.
