Tendinopathy is a condition common to overburdening of a tendon.
When an athlete or other patient seeks traditional medical attention for tendon pain, the first line of treatment is often corticosteroid injections (CSI) to reduce inflammation and ease discomfort.
Oftentimes, steroid injections are given in conjunction with physical therapy, to help the patient withstand the discomforts associated with therapeutic exercises. However, new research suggests that CSI may actually interfere with physical therapy and delay rehabilitation.
Overload is the principle by which muscle and tendon cells become stronger. The idea is to stimulate an adaptive response at the cellular level. Overload is the underlying principle of the maxim, “No pain, no gain.”
It has been demonstrated that slow eccentric (muscle lengthening) movements performed with heavy resistance have a positive effect on strengthening and repairing tendon tissue. Exercise stimulates the formation of new collagen and matrix proteins within the tendon, a process called mechanotransduction, meaning exercise has a positive effect on tendon structure.
Emerging research suggests that while CSI treatment has a positive short-term effect on pain reduction, CSI may interfere with and delay tendon recovery. It appears that local glucocorticoid injections may have a harmful effect on newly forming tendon cells, reducing their viability and proliferation, and delaying the synthesis of collagen.
In addition to tendon cells in the long run.
A growing body of research points to the potentially harmful effects of CSI on tendon rehabilitation:
While evidence about the effect of CSI on tendon recovery is inconclusive, patients with tendinopathy, especially athletes whose careers hinge on recovery, should be wary of CSI as a first line of treatment.
