Importance of preswing rectus femoris activity in stiff-knee gait.
Stiff-knee gait is characterized by diminished and delayed knee flexion during swing. Rectus femoris transfer surgery, a common treatment for stiff-knee gait, is often recommended when a patient exhibits prolonged activity of the rectus femoris muscle during swing. Treatment outcomes are inconsistent, in part, due to limited understanding of the biomechanical factors contributing to stiff-knee ...
متن کاملProximal rectus femoris lengthening.
There are two main problems with muscle tendon lengthening: thinness created by the technical procedure weakens the tendon, and in short tendons, lengthening may not provide enough length for the amount of joint motion required. In proximal rectus femoris lengthening, the distal ends of the reflected and straight heads are sutured together. Using this technique, the tendon will not be thinned, ...
متن کاملRectus femoris transfer and musculo-skeletal modeling: effect of surgical treatment on gait and on rectus femoris kinematics.
Spasticity of the rectus femoris (RF) is one of the possible causes of stiff knee gait (SKG) in cerebral palsy. Musculoskeletal studies have shown that in SKG, length and speed of the RF are affected. No evaluation had been made to quantify the modifications of those parameters after surgery. The effect of this operation on gait quality and on RF kinematics was assessed in this study in order t...
متن کاملRectus Femoris Tendon Calcification
Background: Since it was developed, hip arthroscopy has become the favored treatment for femoroacetabular impingement. Due to recent considerable improvements, the indications for this technique have been widely extended. Injuries of the rectus femoris tendon origin, after an acute phase, could result in a chronic tendinopathy with calcium hydroxyapatite crystal deposition, leading to pain and ...
متن کاملRectus femoris to gracilis muscle transfer with fractional lengthening of the vastus muscles: a treatment for adults with stiff knee gait.
BACKGROUND Stiff knee gait, which may be seen in patients with upper motor neuron injury, describes a gait pattern with a relative loss of sagittal knee motion. It interferes with foot clearance during swing, often leading to inefficient compensatory mechanisms and ambulatory dysfunction. Distal rectus femoris muscle transfers and fractional lengthening of the vastus muscles have been performed...
