What is The TenJet Procedure?


The TenJet System is a minimally invasive surgical procedure designed to treat chronic tendon pain, however it can also be used for chronic plantar fasciitis. TenJet delivers a high-pressure stream of saline that is said to differentiate between healthy and damaged tissue. The flow dynamics of the high powered saline stream create a suction effect, which cuts and removes diseased tissue instantaneously, while sparing healthy tissue. The TenJet is considered to be an improved version of Tenex procedure because the use of water jet is better than the suction of Tenex.

Does it Work?

The TenJet procedure is new and has not been used extensively on plantar heel pain. There are no clinical studies published investigating the success of this procedure for plantar heel pain, however as it is a similar procedure to Tenex, one can reasonably expect it to provide similar success rates.



The TenJet procedure is considered to be safer than the Tenex procedure as through the water jet technology of the TenJet Hydrocision system, scar formation is very easily broken down and removed via negative pressure. With the Tenex system a blade is passed back and forth to break up the scar tissue. This makes the Tenex system far inferior because it also breaks down the good tissue as the probe is passed back and forth. TenJet water jet system, on the other hand, only breaks down the scarred and damaged tissue allowing for less trauma and improved healing capability of the region. 


My Verdict

The principles of the TenJet procedure make sense as the aim of the treatment is to remove/breakdown degenerative tissue in a minimally invasive manner and it sounds like this technology is safer than the Tenex proecedure. Personally I would lean towards other treatment options that have strong evidence to proove their effectiveness prior to considering Tenjet. As TenJet is a newer treatment for plantar fasciitis owing to its recent development, there is lack of evidence available to test how safe and effective this procedure is for plantar fasciitis and until there is more research on this treatment, I will not be actively recommending to my patients. Currently this treatment is not available in the UK.
