Metformin Safety and Efficacy in Osteoarthritis.

Knee osteoarthritis (OA) is a chronic, painful disease associated with considerable morbidity, costs and disability. It is estimated that over a third of people aged over 60 have radiographic knee OA2 and over 50% of these with knee OA will go on to have a total knee replacement in their lifetime. At present there are no licensed treatments that alter disease progress and management is primarily concerned with symptom control to retain or improve joint function, although a trial of strontium ranelate showed promising results.

Geniculate Artery Embolization for Osteoarthritis

The need for exploration of more definitive and cost effective non-arthroplasty treatments of osteoarthritis (OA) has been demonstrated by the orthopedic and health economic research. Embolotherapy of neovessels associated with OA joints has been shown to be promising in patients with knee OA. There is a need for level one evidence drawn from randomized clinical trials to prove the safety, feasibility and efficacy of knee embolotherapy compared to standard of care. This randomized pilot study will assign 10 patients with mild-moderate OA to undergo geniculate artery embolization plus standard of care (defined in this study as: physical therapy and oral anti-inflammatory medications, with a maximum of 1 joint injection at the time of enrollment) and 10 patients to receive only medical standard of care (also having had a maximum of 1 joint injection prior to enrollment). The goal of this pilot study is to obtain preliminary estimates of safety and efficacy of embolotherapy to provide sustained symptom control and modify disease progression in patients with mild to moderate knee OA.

The objective of the study is to evaluate by a randomized controlled, double-blind clinical trial the efficacy and safety of viscosupplementation-associated PRP infiltration compared with PRP-only or HA-only infiltration for the treatment of patients with knee osteoarthritis.

The Role of Vitamin K on Knee Osteoarthritis Outcomes

The appropriate form and dosing of vitamin K to benefit relevant outcomes in knee osteoarthritis (OA) are not known. In intervention studies for conditions other than knee OA (e.g., prevention of cardiovascular disease), the most commonly used forms and doses include phylloquinone (vitamin K1; 1000µg or 500µg daily) or menaquinone-7 (MK-7 or vitamin K2; 300µg daily). However, whether these doses are adequate to increase vitamin K to levels that ameliorate risk of adverse OA outcomes is not known. Furthermore, although some studies suggest enhanced bioavailability of MK-7 over vitamin K1, as well as extra-hepatic effects, whether this is relevant for an older population with knee OA is not known, The overall goal of this pilot randomized clinical trial (RCT) is to test different subtypes and doses of vitamin K supplementation in older adults with knee OA and to measure changes in relevant biochemical measures.

Effects of Fall Prevention Program on the Number of Falls Among Elderly Following Total Knee Replacement

Effects of Vitamin K on Lower-extremity Function in Adults With Osteoarthritis:

The overall goal of this pilot randomized trial is to obtain necessary prerequisite data to conduct a randomized controlled intervention to test the effect of vitamin K supplementation on knee osteoarthritis progression and related functional decline. To address critical parameters required to design this larger RCT, we will conduct a double-blind, 2-armed, parallel-group intervention study, with a placebo run-in, in which 50 adults with mild to moderate knee OA and low baseline vitamin K status will be randomly assigned to 1 mg phylloquinone/day or matching placebo, and treated for 6 months. Specifically, we will: (1) compare the effects of 1 mg/day phylloquinone vs. placebo on the non-functional circulating form of MGP; (2) estimate rates of recruitment and retention, follow-up rates and reasons for loss to follow-up, response rates to questionnaires, adherence/compliance rates, and potential for site differences; and (3) determine the responsiveness of the Osteoarthritis Research Society International (OARSI)-recommended performance-based tests of physical function in adults with low vitamin K status and mild to moderate knee osteoarthritis. We will also obtain preliminary data on the distribution of MGP genotype at two clinical sites for effect size generation. As of February 2025, based on attrition rate below what was initially expected, we revised our planned enrollment from 50 to 35, to achieve the original goal of 30 completers. This was approved by the study sponsor.
