Osteoarthritis of the Knee

The study compares two exercise strategies in people with knee osteoarthritis. The first is aerobic exercise on a recumbent cycle ergometer, with effort controlled by the Borg scale. The second is a therapeutic exercise program with resistance, neuromuscular, mobility, and balance components. The primary objective is to determine which approach produces greater exercise induced hypoalgesia, measured by the increase in pressure pain threshold at the knee within the session across four anchor sessions during a ten week program. This is a randomized clinical trial with two parallel arms. Ninety participants, between forty five and seventy five years of age, will be allocated to one of the two groups. Allocation sequence concealment will be ensured using opaque envelopes. The outcome assessor will remain blinded to group allocation. The interventions will take place three times per week for ten weeks. Assessments will be performed at baseline and after ten weeks. Within session measurements will also be taken in weeks one, four, seven, and ten. The primary outcome is the intra session change in pressure pain threshold at the medial compartment of the knee. Secondary outcomes include exercise induced hypoalgesia in the quadriceps and trapezius, chronic adaptation of pressure pain threshold, conditioned pain modulation, pain intensity, pain self efficacy, knee related health status, functional performance, quadriceps strength, global perceived effect, and adherence. The planned sample size is forty five participants per group. The analysis will follow the intention to treat principle. The primary outcome will be compared using linear mixed models with group and time effects. Clinical outcomes at T1 will be adjusted for baseline values. Estimates, confidence intervals, and interpretation in light of minimally important differences will be reported.

This study aims to understand the safety, drug concentration and distribution of an intra-articular injectable formulation of celecoxib, AVD275, in patients with knee osteoarthritis. One single injection at three different doses of the drug will be studied in a sequential order, and each participant will be monitored for 24 weeks over ten clinical visits.

To evaluate the efficacy and safety of CLS2901C human allogenic chondrocyte sheets used in the osteotomy + RMSC group compared to in the osteotomy alone group of patients with osteoarthritis of the knee (OAK).

This clinical trial is being done to better understand how daily treatment with Tetrahydrocannabinol (THC), Cannabidiol (CBD), or the combination of CBD plus THC affects knee osteoarthritis pain and other related symptoms. Consented participants will have a screening period and visit (up to 30 days to treatment start). If participants pass the screening phase, they will be randomly assigned to take one of the investigational study drugs. For this study, participants will not know when or if they are taking CBD, THC, THC plus CBD, and when or if taking placebo. Clinical pain will be assessed at multiple times throughout the study, and eligibility will be re-assessed at two weeks into the treatment period. It is possible that subjects will not be able to participate in the study after 14 days of of treatment. The treatment period will take approximately 16 weeks and then a follow-up period for approximately 2 weeks. In addition to treatment, participants will have clinical assessments, blood draws, questionnaires, daily pain diaries, sensory testing, as well as have functional connectivity magnetic resonance imaging (fcMRI).

Prospective single-masked (study participant will be masked), randomized controlled trial to examine the influence of BMAC on patient-reported outcomes (PROs) in patients with primary knee osteoarthritis.

Rationale for conducting the study: The study aims to systematically evaluate the clinical and economic impacts of Robotic-Assisted Total Knee Replacement (RTKR) compared to conventional Total Knee Replacement (TKR). It focuses on the potential benefits of RTKR, including improved precision in surgery, potentially leading to better patient outcomes and reduced healthcare costs. Our primary endpoint is the Forgotten Joint Score (FJS), aimed at measuring patients awareness of their knee joint in everyday life, indicating the success of the knee replacement surgery in restoring natural joint function. Secondary endpoints include patient-reported outcome measures (PROMs), patient activity levels, the accuracy of implant positioning on x-ray, and the incidence of adverse events. Study design: Multicentre,, preference-tolerant, randomized, controlled, superiority trial with two treatment arms that compares the outcomes of RTKR with traditional TKR techniques. Study population: Adult patients aged 18 years and older who are eligible for TKR as per local guidelines and who have given informed consent to participate in the study. Number of patients: 400 Inclusion criteria: Patients must be adults aged 18 years and older, eligible for TKR according to local guidelines, and willing to participate in the study. Exclusion criteria: Patients with extreme malalignment requiring special implants or techniques, patients unfit for surgery due to medical reasons, and those deemed unsuitable to participate in the study for other reasons. Primary outcome variables: The Forgotten Joint Score (FJS) at 2 years after surgery
