PURPOSE This study was performed to determine the incidence of acute bone-patellar tendon-bone autograft harvest complications after anterior cruciate ligament (ACL) reconstruction. METHODS Over a nearly 20-year period (September 1986 to April 2006), 1,725 consecutive patients underwent primary ACL reconstruction using bone-patellar tendon-bone autograft by 3 fellowship-trained sports medicin...

background:the aim of this study is to find out the spatial and temporal expression of tgf-b1 during the tendon healing, after application of platelet rich plasma (prp). methods: a patellar tendon defect model in rabbits was used for this purpose. 48 skeletally mature new zealand white rabbits, weighing 3.5 kg, were used for this study. equal numbers of animals from both groups were sacrificed ...

Seventy patients with patellar tendon or hamstring tendon autografts for single-incision anterior cruciate ligament reconstruction were evaluated at least 2 years after surgery. All reconstructions were performed by the same surgeon, and metal interference screws were used for fixation of all grafts. No significant differences were noted between groups for Lysholm score, reduction in activity, ...

A 58-year -old man with a past history of acquired emphysema was admitted after his legs 'gave way' as he walked down a short flight of steps. He was unable to extend either knee actively. Bilateral patellar tendon ruptures were diagnosed clinically from the history, and the finding of swelling and a palpable gap below the lower pole of each patella. The diagnosis was confirmed radiologically (...

PURPOSE This study was undertaken to evaluate the histologic and ultrastructural characteristics of the patellar tendon 10 years after reharvesting its central third. HYPOTHESIS In the long term, after its central third is reharvested, the patellar tendon does not regain a normal histological and ultrastructural appearance. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Tw...

INTRODUCTION chronic patellar tendon rupture is rare and its incidence and prevalence are unknown. Furthermore, the data about late reconstruction of the patellar tendon in rheumatoid arthritis is limited. Such condition, if not managed properly, can substantially affect the patient's activities of daily living. CASE PRESENTATION We report a case of chronic patellar tendon rupture in a 49 yea...

Disruption of the knee extensor apparatus, after harvesting the central third of the patellar tendon for a bone-tendon-bone autograft, is a rare complication. We made 2215 reconstructions of the anterior cruciate ligament of the knee using bone-patellar tendon-bone technique, and 10 patients had fracture of the patella (0.45%), and fore patients had rupture of the patellar tendon (0.18%). The f...

We assessed the histologic, mechanical, and structural properties of the reharvested central-third patellar tendon in greyhounds. Twelve dogs had the central third of the patellar tendon (5 mm) removed with corresponding bone blocks from the patella and tibia; the remaining tendon defect was loosely closed. Six dogs were sacrificed at 6 months and six at 12 months, and the central third of the ...

Acute simultaneous rupture of the anterior cruciate ligament (ACL) and patellar tendon is a rare injury. We present a case report of a 32-year-old male patient with ruptured ACL and ipsilateral patellar tendon rupture sustained while playing baseball. Surgery was performed on the patellar tendon and the ACL simultaneously. The clinical and radiological outcomes of the treatment were successful....

Simultaneous rupture of both the patellar tendon and the anterior cruciate ligament is a relatively rare injury. Its diagnosis can easily be missed during the initial examination. Treatment options include immediate repair of the patellar tendon with either simultaneous or delayed reconstruction of the ACL. We present the case of a combined rupture of the patellar tendon, the anterior cruciate ...
