A new reconstruction of the patellar tendon was performed in a 43-year-old patient who lost tendon and tibial tuberosity after a wide tumor resection for low-grade myofibroblastic sarcoma of the parapatellar tendon. In this technique, the patellar tendon was anatomically reconstructed using a fascia lata attached to the iliac bone. The iliac bone was fixed to the tibial bony trough with absorba...

We present the case of a combined lesion of the medial collateral ligament (MCL) and patellar tendon of the knee in a 45-year-old man, after a fall while skiing. Although there are numerous publications concerning associated tears of MCL and other knee ligaments, a combination of MCL tear with a rupture of the patellar tendon is very rare. After a review of the literature and treatment guidelin...

Patellofemoral pain (PFP) is thought to be related to patellar maltracking due to imbalances in the knee extensor. However, no study has evaluated the in vivo biomechanical properties of the quadriceps tendon in PFP syndrome. Our purpose was to compare the biomechanical properties of the quadriceps tendons in vivo and noninvasively in patients with PFP syndrome to those of control subjects. The...

Surgical reattachment of tendon and bone such as in rotator cuff repair, patellar-patella tendon repair and anterior cruciate ligament (ACL) reconstruction often fails due to the failure of regeneration of the specialized tissue ("enthesis") which connects tendon to bone. Tendon-to-bone healing taking place between inhomogenous tissues is a slow process compared to healing within homogenous tis...

Anterior cruciate ligament reconstruction with patellar tendon allograft tissue is a common orthopedic procedure. It is unknown what effect, if any, the donor age has on clinical outcomes. Biomechanical studies have shown the strength of cadaveric patellar tendon to be independent of age, but no clinical studies have evaluated patient outcomes related to this variable. The purpose of this study...

BACKGROUND Proximal patellar tendinopathy/jumper's knee (PT/JK) is well known to be difficult to treat. Recent studies using an ultrasound and colour Doppler-based treatment approach on the dorsal side of the tendon, sclerosing polidocanol injections and ultrasound-guided arthroscopic shaving, have shown promising clinical results. OBJECTIVES To compare the clinical effects after treatment wi...

Objective: Expansion of the extracellular matrix is a prominent but poorly characterized feature of tendinosis pathology. We aimed to characterize the extent and distribution of the large aggregating proteoglycan versican in patients with patellar tendinosis. Methods: Tendon was obtained from tendinopathy patients undergoing debridement of the patellar tendon and from controls undergoing intram...

The investigation of patellar tendon reflex involves development of a reflex hammer holder, kinematic data collection and analysis of patellar reflex responses using motion analysis techniques. The main aim of this research is to explore alternative means of assessing reflexes as a part of routine clinical diagnosis. The motion analysis system was applied to provide quantitative data which is a...

Aim: This study aims to investigate the length, width and thickness of patellar tendon type length patella with MRI reveal normal values ​​of morphology specific Turkish population.
 Material Method: The was conducted 348 individuals (137 males, 211 females) who applied our hospital, had no anterior knee pathology, MRIs. proximal distal tendon, type, prepatellar infrapatellar fat pad signa...
