Sclerosing injections targeting the area with neovessels and nerves on the dorsal side of the patellar tendon has been demonstrated as giving promising clinical results in patients with chronic painful Jumper’s kneepatellar tendinosis PT However a mean number of three treatments with 6–8 weeks in between were needed for a good clinical result This study aimed to evaluate a more radical removal of the area with neovessels and nerves by using arthroscopic shaving Fifteen patients 12 men and three women with the diagnose Jumper’s kneePT in altogether 15 patellar tendons were included All patients had a long duration of painsymptoms mean 27 months from the patellar tendon and ultrasonography US + colour Doppler CD examination showed structural tendon changes with hypoechoic areas and a neovascularisation inside and on the dorsal side of the tendon corresponding to the painful area All patients were treated with arthroscopic shaving of the dorsal side of the proximal tendon At followup mean 6 months after treatment there was a good clinical result in 13/15 tendons 6/8 elite athletes The satisfied patients were back to previous before injury sport activity level and the amount of pain recorded on a visual analogue scale VASscale had decreased significantly VAS from 79 to 12 P 005 A telephone followup 13 months mean postoperatively showed that the same 13/15 were still satisfied and active in their sports and that the 2/15 poor cases were still not satisfied with the treatment Our shortterm results indicate that arthroscopic shaving targeting the area with neovessels and nerves on the dorsal side of the patellar tendon has a potential to reduce the tendon pain and allow for the majority of patients to go back to full tendon loading activity within 2 months after surgery Further studies evaluating this new technique for treating Jumper’s kneePT are in progress
