Research Study Confirms “Why You Should Not Get Injections for Knee Arthritis”

A knee injections is one of the last resort treatments – after natural anti-inflammatories, physical therapy and knee exercises.

Here’s why – beside the potential further knee cartilage damage, this study from National Institutes of Health Bethesda showed your thigh muscles turn off after knee injections making your bad knee even weaker and more painful.

OBJECTIVE: We tested the hypothesis that intrusion of the knee joint capsule alters quadriceps muscle metabolism and function independently from the damage induced to knee cartilage.

RESULTS: The interventional groups produced values of Pi/PCr ratio, [PCr], contractile force and pH that were significantly different from CTL. These changes in muscle function were accompanied by higher concentrations of interleukin-1 observed with PIA and SAL.

We did not observe any effect of cartilage damage on muscle function or metabolism.

CONCLUSIONS: Knee joint intrusion alters quadriceps muscle metabolism with accelerated depletion of energy stores and fatigue during stimulation. This study demonstrates that needle intrusion into the knee joint results in muscle dysfunction, independently from the extent of cartilage damage.

Dr. Paul’s Comments: Knee injections are never a good idea as a first line knee treatment.  Natural anti-inflammatories, physical therapy and knee exercise are much better choices!
