CoQ10 alleviates knee osteoarthritisCoenzyme Q10 ameliorates pain and cartilage degradation in a rat model of osteoarthritis by regulating nitric oxide and inflammatory cytokines.
Directly assesses CoQ10 efficacy
We explored the impact of Coenzyme Q10 (CoQ10) on knee pain and cartilage health using a rat model of osteoarthritis (OA). Our investigation involved inducing OA in rats through an injection of monosodium iodoacetate into the knee joint. Subsequently, we administered CoQ10 orally starting on the fourth day after the injection.
Pain severity was evaluated by assessing tactile sensitivity, and we also examined the state of cartilage by measuring its thickness and proteoglycan levels. Notably, CoQ10 demonstrated a significant reduction in pain, indicated by increased pain withdrawal thresholds. We observed that the treatment led to a decrease in cartilage degeneration as well.
Moreover, CoQ10 lowered the levels of several inflammatory markers associated with OA, including matrix metalloproteinase-13 and various interleukins. Based on our findings, we conclude that CoQ10 is a promising option for alleviating pain and protecting cartilage in individuals suffering from osteoarthritis.

CoQ10 reduces knee pain post-surgeryCoenzymeQ10 and Ischemic Preconditioning Potentially Prevent Tourniquet-Induced Ischemia/Reperfusion in Knee Arthroplasty, but Combined Pretreatment Possibly Neutralizes Their Beneficial Effects.
Study includes complicating factors.
This study examined the effects of coenzyme Q10 (CoQ10) and ischemic preconditioning (IPC) on knee pain following total knee arthroplasty (TKA). We enrolled 44 patients in four groups: a control group, a group receiving CoQ10, a group undergoing IPC, and a group that received both treatments.
CoQ10, taken at a dosage of 300 mg per day for 28 days, showed some positive effects by reducing pain scores and lowering the need for morphine up to 24 hours after surgery. We noted that CoQ10 improved baseline mitochondrial function, suggesting it may aid in recovery after the surgical and ischemic effects of the tourniquet used in TKA.
However, when CoQ10 was combined with IPC, the beneficial analgesic effects were negated. IPC alone did enhance mitochondrial function and provided a temporary boost in energy production, but it seems that the combination interfered with the individual advantages offered by each treatment. Overall, while CoQ10 appears to help in reducing knee pain post-surgery, its benefits could diminish when used alongside IPC.
