Abstract

Patellar tendinopathy is one of the most common injuries caused by overuse. Generally, histological findings in tendinopathy indicate a degenerative process and loss of healing response. The symptoms of tendinopathy are pain and/or disability due to pain. Although many treatment methods are available for patellar tendinopathy, no consensus has been reached as to the proper use of these therapies because of the limited evidence from their application. Only eccentric exercise has strong evidence of effectiveness for patellar tendinopathy. Moderate evidence was found for heavy slow resistance training. Moreover, the evidence for sclerosing injections, shockwave therapy, and surgery is limited. The success rate of conventional conservative treatment of tendinopathy, including eccentric exercise, was >80%. For the remaining patients, invasive therapies such as arthroscopic and open surgeries are needed. The success rate of surgery for patellar tendinopathy was reported to be 60–90%. The mean period of return to sports after arthroscopic surgery was significantly shorter than that after open surgery, although the success and return-to-play rates were not significantly different between open and arthroscopic surgeries.
