During the recent years, a few studies have shed new light on the innervation patterns of the
human patellar tendon, but the area of the loose paratendinous connective tissue dorsal to
the proximal tendon proper has yet not been investigated. That is a drawback, since this is
the area targeted in promising treatment regimens of chronic painful patellar tendinosis,
namely sclerosing Polidocanol injection therapy, and a new surgical method conforming to
ultrasound and color Doppler guided arthroscopic shaving, directed at neovessels found in …

Tendinosis is a condition of chronic pain that afflicts several human tendons, not least the
patellar tendon, in which case it is often clinically referred to as 'jumper's knee'. The exact
mechanisms behind tendinosis are yet not fully understood. One draw-back in the case of
patellar tendinosis has been the lack of knowledge of the innervation patterns of the human
patellar tendon. It cannot be excluded that the processes of tendinosis are influenced by
nerve mediators, released from nerve endings or from stimulated cells inside the …
