Chronic disruption of the extensor mechanism is a devastating problem after total knee arthroplasty. Quadriceps tendon ruptures occur at an estimated 0.1% prevalence in the setting of total knee arthroplasty. Complete tears of the quadriceps tendon generally have poor results and high rates of rerupture. We present a case of a quadriceps tendon rupture after total knee arthroplasty which reruptured after initial direct repair. The patient presented to us with a chronically retracted rerupture and was subsequently reconstructed successfully with a novel extended medial gastrocnemius-soleus-calcaneus local rotational pedicle flap...

In this article, we report a case with spontaneous rupture of extensor pollicis longus tendon due to calcified extensor carpi radialis tendon group, which has not been published in the literature previously. Successful thumb extension was achieved in a 68-year-old male patient with the transfer of the extensor indicis proprius tendon at two months postoperatively. It appears that calcified extensor carpi radialis tendon group constitutes high risk for a possible attritional rupture of the extensor pollicis longus tendon...

Frogs' outstanding jumping ability has been associated with a high power output from the leg extensor muscles. Two main theories have emerged to explain the high power output of the frog leg extensor muscles, either (i) the contractile conditions of all leg extensor muscles are optimized in terms of muscle length and speed of shortening, or (ii) maximal power is achieved through a dynamic catch mechanism that uncouples fibre shortening from the corresponding muscle-tendon unit shortening. As in vivo instantaneous power generation in frog hind limb muscles during jumping has never been measured directly, it is hard to distinguish between the two theories...

PURPOSE: Metacarpal fractures are commonly treated by a variety of means including casting or open reduction internal fixation when unacceptable alignment is present following attempted closed reduction. Dorsal plating with either single-row 2-dimensional or double-row 3-dimensional plates has been proposed. This study's purpose was to determine if there are any differences in fixation construct stability under cyclic loading and subsequent load to failure between the lower profile 3-dimensional and the larger 2-dimensional plates in a metacarpal fracture gap sawbone model...

OBJECTIVES: To characterize abnormalities in the dorsal extensor tendons of the hand and determine the importance of these findings in rheumatoid arthritis. METHODS: A retrospective cross-sectional study was done on 26 patients with rheumatoid arthritis who had sonography of their hands. B-mode and power Doppler joint activity were scored, and the extensor tendons were examined for B-mode changes and power Doppler signals. B-mode changes included anechoic fluid around tendons, hypoechoic tissue around tendons, paratendon tissue and tendon thickening, as well as vascularity around the tendon, for which peritendon power Doppler signals were recorded...

Patellar duplication is a rare asymptomatic condition. The diagnosis is often made following a traumatic event associated with an injury to the knee extensor mechanism. The treatment is often surgical and consists in removal of the smaller part of the patella with tendon reinsertion. The presence and rupture of an intermediate tendon between the two parts of the patella have not been reported in the modern literature. We present a traumatic rupture of an intermediate tendon in a patient with horizontal patellar duplication...

REVIEW
Omri Ayalon, Nader Paksima
The management of distal radius fractures has evolved over time from a largely nonoperative paradigm to a more commonly performed operative procedures today. Surgical trends have similarly developed, with dorsal plating falling out of favor due to complications involving extensor tendon pathology as well as due to the ubiquity of the volar plate along with the advent of locking plate technology. However, with the improvement in design of newer generation dorsal plates, this technique should be used in the appropriate clinical situation, including dorsal comminution and angulation with concomitant carpal pathology...

M Severyns, G Renard, R Guillou, G A Odri, O Labrada-Blanco, J L Rouvillain
Acute quadriceps tendon ruptures disrupt the continuity of the extensor mechanism and must be treated surgically. Tendon reattachment with suture anchors has recently been shown to be biomechanically superior to reattachment through transosseous tunnels. In this context, arthroscopy is an interesting alternative. It can limit postoperative wound healing and infectious complications, while ensuring functional outcomes that are equivalent to standard techniques. The goal of this technical note is to describe an original, reproducible method for arthroscopic reattachment of the quadriceps tendon with suture anchors...
