The simultaneous diagnosis of ipsilateral patellar tendon rupture and anterior cruciate ligament tear is rare. Surgical repair is complicated by different rehabilitation regimens as well as anterior cruciate ligament graft choices. We present a case where at the same operative setting, the patellar tendon was repaired, and the anterior cruciate ligament reconstructed with autologous hamstring g...

A series of surgically treated patellar tendon lesions among athletes is presented. The material was collected during 5 years from three sports injury clinics and from two hospitals. During this period the authors treated about 150 cases of jumper's knee, of which 34 cases were treated by operation. The athletes were mostly volley ball players, jumpers or runners. The operation revealed a necro...

BACKGROUND Acute bilateral patellar tendon rupture is a rare occurrence, with only 1 case reported in the English literature of a young, fit athlete with no regular medications. To our knowledge this is the first such case reported using a LARS reconstruction. CASE PRESENTATION A 26-year-old otherwise well ex-olympic gymnast with bilateral acute on chronic patellar tendon rupture underwent re...

Patellar tendinopathy is a common and difficult-to-treat overuse injury of the patellar tendon with a very negative impact on the careers of many athletes. It appears to involve a failed healing process in the tendon – not inflammation – and has consequences for the treatment strategy. Rehabilitation programs are based on the principles of load reduction and an eccentric exercise program to imp...

The current report presents the case of a 41-year-old male exhibiting a giant cell tumor of the tendon sheath (GCT-TS) arising from the patellar tendon sheath. Plain radiography and magnetic resonance imaging revealed a well-localized mass that wrapped around the patellar tendon, and extended from the subcutis into the infrapatellar fat pad and tibia. Following histopathological determination o...

Doppler ultrasound examination revealed signs of tendinosis with significant neovascularity, formed by immature tortuous and dilated vessels into intratendinous mass (Figure 1A). Furthermore, color Doppler scans showed areas of intratendinousedema in the proximal patellar-tendon interface (Figure 1A). After discussing the various treatment options, the patient opted to try etamsylate injection ...

A 46-year-old man presented to the Emergency Department (ED) with left knee pain after being assaulted and landing on a flexed knee. On physical examination, the patient had a large effusion of his left knee and the patella was retracted proximally. He was unable to bear weight on his left leg, range his knee, or hold his leg up against gravity due to pain. The left extremity was neurovascularl...

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...
