TenJet for Chronic Tendinitis

TenJet Physician Finder

What is TenJet?

TenJet is a needle-like device specifically designed to treat tendinosis or chronic tendinitis and provide relief from chronic tendon pain. The device uses a pressurized, high-velocity jet of saline to selectively resect and remove diseased tendon tissue while sparing healthy tissue.

TenJet enables sports medicine physicians to treat patients suffering from chronic tendon pain due to Tennis Elbow or Golfers’ Elbow, Jumper’s knee, Achilles tendinosis, or tendon calcifications in the shoulder, elbow, hamstring, or hip. It can also be used to treat plantar fasciitis.

The minimally invasive tendon treatment requires only a small incision, is performed in an outpatient setting using real-time ultrasound imaging to visualize the diseased tissue, and aims to accomplish the goal of diseased tissue resection similar to open or arthroscopic surgery.

Frequently Asked Questions

At the beginning of the procedure, you may feel some discomfort when the physician administers a local anesthetic.  After your treatment, you may feel soreness in the treated area as the anesthetic wears off. 

On average, you should start experiencing improvement in tendon pain as early as 2 weeks after the procedure and continue to experience significant relief within three months of being treated for chronic tendinitis or tendinosis. Your physician will guide your post-treatment recovery plan through physical therapy and/or home exercises. Individual patient results and time to complete symptom relief may vary depending on compliance with post-procedure instructions and other variables. 

When TenJet is used in a minimally invasive procedure, stitches may not needed.

Most insurance companies provide reimbursement for tendon treatment procedures. TenJet may be used by your physician to perform the procedure.

Tendinitis vs Tendinosis

Most tendon injuries fall into two categories: Tendinitis and tendinosis

Tendinitis and tendinosis are different types of tendon injury. Although tendinosis is often referred to as chronic tendinitis, understanding which condition is affecting you could impact your treatment and time to resolution, as each requires different treatment approaches.

Tendon injuries can result from a single incident or activities that involve repetitive motion, resulting in micro-tears within the collagen fibers of the tendon.

Healthy Tendon

A healthy tendon is made up of strong, flexible bands of connective tissue that transmit the energy needed to create movement from muscle to bone. Ligaments, such as the plantar fascia, have a similar structure and composition to tendons and can develop injuries similar to tendons.

Tendinitis

Tendinitis refers to an inflamed tendon usually resulting from an acute injury or strain on the tendon. The condition can result in pain and tenderness in the fibrous connective tissue outside of the joint between the muscle and the bone.

Tendinosis

Tendinosis refers to a tendon with a breakdown in its structure and disorganized collagen fibers. At this stage, tendons may retain fluid, develop calcifications, and, if left untreated, develop partial tears or even full-thickness tears with a risk of rupture.
