Jumper's knee or infrapatellar insertional tendinopathy is a condition prim
arily found in athletes between 18 and 25 years of age who are engaged in e
xplosive running and jumping sports. It is caused by microtears or partial
macrotears through the patellar tendon. Conservative treatment is used as t
he primary approach. If conservative measures are insufficient or fail to r
elieve the symptoms, surgery is indicated. The patellar tendon is incised a
nd the hyaline inflammatory tissue is removed. Twenty-six patients have bee
n studied retrospectively, with specific attention to postoperative resumpt
ion of sports and residual subjective and objective findings. They all comp
leted a detailed questionnaire and subsequently underwent a physical and ul
trasound examination.
