Patellar Tendinosis: (Jumper's Knee) POLIDOCANOL: Alfredson et al (2005)
Alfredson H; Ohberg L Neovascularisation in chronic painful patellar tendinosis--promising results after sclerosing neovessels outside the tendon challenge the need for surgery. Knee Surg Sports Traumatol Arthrosc (Germany), Mar 2005, 13(2) p74-80
Dr. Reeves' Notes: Fifteen elite or recreational athletes with patellar tendinosis/jumpers knee were injected with Polidocanol, targeting areas of neovascularization. At 6 month followup there was a good clinical result in 12/15 tendons. With previous sport level reached in 12/15 and pain decrease (VAS) from 81 to 10 on a 100 point scale.
An abstract of the study is available below.
Sclerosing injections targeting neovascularisation have been demonstrated to give promising clinical results in patients with chronic painful Achilles tendinosis. In this study, fifteen elite or recreational athletes (12 men and three women) with the diagnosis patellar tendinosis/Jumper's knee in 15 patellar tendons were included. All the patients had a long duration of pain symptoms (mean = 23 months) from the patellar tendon, and ultra-sonography + colour doppler examination showed structural tendon changes with hypo-echoic areas and a neovascularisation, corresponding to the painful area. The patients were treated with ultrasound and colour doppler-guided injections of the sclerosing substance Polidocanol, targeting the area with neovascularisation. At follow-up (mean = 6 months) after a mean amount of three treatments, there was a good clinical result in 12/15 tendons. The patients were back to their previous (before injury) sport activity level, and the amount of pain recorded on a VAS-scale had decreased significantly (VAS from 81 to 10). Our findings indicate that treatment with sclerosing injections, targeting the area with neovessels in patellar tendinosis, has the potential to cure the pain in the tendons and also allow the patients to go back to full patellar-tendon loading activity.
