Tendon injuries account for a substantial proportion of overuse injuries in sports. Despite the morbidity associated with patellar tendinopathy in athletes, management is far from scientifically based. After highlighting some aspects of clinically relevant basic science, we aim to (a) review studies of patellar tendon pathology that explain why the condition can become chronic, (b) summarise th...

Knee dislocations are rare injuries. They represent a severe soft tissue injury following high-energy blunt trauma. We report a case of open posterior knee dislocation with rupture of the patellar tendon and a fracture of the tibial plateau. The treatment was surgical and consisted of reduction of the knee dislocation, fixation of the tibial plateau fracture by lag screws, and transosseous sutu...

A case is reported of bilateral patellar tendon rupture in a fit man after a fall. He had a history of repeated local steroid injections into both tendons and histology confirmed steroid-induced changes. The history of repeated local steroid administration has to be implicated as the cause of this extremely rare injury in this patient, which can also be associated with hyperparathyroidism, syst...

Tendons are important for optimal muscle force transfer to bone and play a key role in functional ability. Changes in tendon properties with aging could contribute to declines in physical function commonly associated with aging. We investigated the in vivo mechanical properties of the patellar tendon in 37 men and women [11 young (27 +/- 1 yr) and 26 old (65 +/- 1 yr)] using ultrasonography and...

BACKGROUND Patellar tendinopathy (PT) is one of the most common knee disorders among athletes. Changes in morphology and elasticity of the painful tendon and how these relate to the self-perceived pain and dysfunction remain unclear. OBJECTIVES To compare the morphology and elastic properties of patellar tendons between athlete with and without unilateral PT and to examine its association wit...

Tendon rupture in systemic lupus erythematosus (SLE) is a rare complication that appears to occur in patients receiving corticosteroid therapy. A case is presented with sequential bilateral rupture of Achilles tendon and unilateral rupture of a patellar tendon. Six more published cases are reviewed. Tendon rupture in SLE has affected both males and females between the ages of 24 and 63 years. I...

BACKGROUND Palpation is an important clinical test for jumper's knee. OBJECTIVES To (a) test the reproducibility of palpation tenderness, (b) evaluate the sensitivity and specificity of palpation in subjects with clinical symptoms of jumper's knee, and (c) determine whether tenderness to palpation may serve as a useful screening test for patellar tendinopathy. The yardstick for diagnosis of p...

BACKGROUND The nature of tendon neovascularisation associated with pain over time has not been studied. OBJECTIVE To prospectively study the patellar tendons in elite junior volleyball players. METHODS The patellar tendons in all students at the Swedish National Centre for high school volleyball were evaluated clinically and by ultrasonography (US) and Power Doppler (PD) sonography. RESUL...
