BACKGROUND Patellar tendinosis (PT), or "jumper's knee" is a common condition in athletes participating in jumping sports, and is characterised by proximal patellar tendon pain and focal tenderness to palpation. Hypoechoic lesions observed in the proximal patellar tendon associated with the tendinosis are typically described as being a result of degenerative change or "failed healing". We propo...

Today, the treatment of patellar luxations using current techniques has become a very common procedureas part of the surgical treatment. Nevertheless, there are some doubts about such procedures in restraining the patella in lower grade cases. The purpose of the present retrospective clinical study was to determine theefficacy of the soft tissue and bone reconstructive procedures used for vario...

We describe a rare case of a patellar tendon "re-rupture" at the opposite end of a previous proximal tendon repair. A 32-year-old male with a history of surgically repaired right proximal patellar tendon rupture presented with an acute non-traumatic right knee pain and instability during sports. Magnetic resonance imaging confirmed a complete rupture of his distal patellar tendon at the tibial ...

Patellar tendon rupture is a rare, but major event that often requires surgical repair in order to reestablish function of the extensor mechanism of the knee. Rupture of the tendon usually occurs in the 3rd or 4th decade of life and results from slip and fall accidents, or powerful contraction of the quadriceps such as during sporting events or weight lifting [1-3]. Anterior Cruciate Ligament (...

Chronic patellar tendinopathy is a common clinical condition that is managed by physical therapists and is common among athletes and non-athletes alike. Patellar tendinopathy is characterized by the absence of inflammatory cells and prostaglandins and an increased presence of fibroblasts and disorganized collagen (1). Therefore, this condition is not inflammatory as physicians had thought but i...

PURPOSE To examine the influence of two patellofemoral braces on pain response, patellar alignment, and patellofemoral joint contact area in persons with patellofemoral pain. METHODS Fifteen women between the ages of 18 and 45 yr with a diagnosis of patellofemoral pain participated. After the assessment of pain response using a visual analog scale, subjects underwent axial plane magnetic reso...

Macrotraumatic extensor mechanism complications do occur after central third patellar tendon harvest for anterior cruciate ligament (ACL) reconstruction and include intraor postoperative patella fracture and patellar tendon rupture. These are significant complications that often require additional surgery. Intraoperative precision when harvesting the patellar tendon, bone grafting the donor sit...

Background and purpose - Knee pain after total knee arthroplasty (TKA) is not uncommon. Patellar retention in TKA is one cause of postoperative knee pain, and may lead to secondary addition of a patellar component. Patellar resurfacing in TKA is controversial. Its use ranges from 2% to 90% worldwide. In this randomized study, we compared the outcome after patellar resurfacing and after no resur...
