Article Abstract
Unlabelled: We assessed the outcome after reconstruction of traumatic, complete, infected, extensor mechanism loss attributable to high-velocity open knee injuries in eight consecutive patients (all males) who presented to us between February 2005 and September 2007 at an average followup of 24 months. All were treated with gastrocnemius flaps. The loss in extensor mechanism was the patellar tendon in five patients, patella and patellar tendon in two patients, and combined patella, quadriceps, and patellar tendon in one patient. The size of the defect ranged from 8 x 5 cm to 15 x 15 cm. The patients were evaluated for functional outcome of the knee, resolution of infection, range of flexion of the knee, and return to work. Four patients had an excellent outcome whereas the others had a good outcome using the Hospital for Special Surgery knee rating scale. All flaps healed primarily with resolution of infection. The average knee flexion was 110 degrees. All patients except two returned to their original occupation. Three patients had an extensor lag of 5 degrees. The gastrocnemius flap is a good option for open knee injuries with extensor mechanism loss, giving consistent results across a wide spectrum of presentation.

Effects of Blood Flow Restriction Combined with Aerobic Stepping Exercise in Sarcopenia: A Study Protocol for a Randomized Clinical Trial.
Int J Gen Med

School of Nursing, Suzhou Medical College of Soochow University, Suzhou, Jiangsu, 215006, People's Republic of China.
Background: Blood flow restriction training (BFRT) can produce effects similar to high-intensity exercise at lower intensities, making it a potentially more suitable method for older adults with sarcopenia. This study aims to determine the efficacy of the intervention on improving physical fitness in older adults with sarcopenia when blood flow restriction (BFR) and aerobic exercise (AE) are combined (BFR-AE) and to explore the related metabolic and signaling mechanisms.
Methods: This is a three-arm, parallel, randomized controlled trial.
RNAi of the elastomeric protein resilin reduces jump velocity and resilience to damage in locusts.

Resilin, an elastomeric protein with remarkable physical properties that outperforms synthetic rubbers, is a near-ubiquitous feature of the power amplification mechanisms used by jumping insects. Catapult-like mechanisms, which incorporate elastic energy stores formed from a composite of stiff cuticle and resilin, are frequently used by insects to translate slow muscle contractions into rapid-release recoil movements. The precise role of resilin in these jumping mechanisms remains unclear, however.

This article aims to present a comprehensive technical note detailing our preferred treatment approach for tibial tuberosity avulsion fractures in the adult and elderly populations, particularly in scenarios characterized by low tissue quality and limited bone stock. Existing literature on this fracture type is scarce, with many described techniques relying on optimal bone quality for effective screw fixation of the tibial tuberosity. Various methods for tibial tuberosity avulsion fixation include K-wires, cannulated screws, staples, tension bands, suture anchors, and in select cases, direct transosseous sutures.

Case: A 67-year-old woman sustained a periprosthetic tibial tubercle avulsion fracture with extensor mechanism disruption. She underwent open reduction internal fixation (ORIF) with orthogonal mini-fragment plates applied in a tension band fashion with patellar tendon suture augmentation. Radiographs, range of motion, and patient-reported outcomes were completed over 1 year.

Objectives: There is a lack of literature regarding the surgical management of high-grade patellar luxation in cats. Among the available options, corrective osteotomies are suitable for correcting severe bone deformities. Therefore, this study aimed to report on the surgical management of grade IV medial patellar luxation (MPL) through tibial corrective osteotomies in two cats.
