Matrix-induced autologous chondrocyte implantation is a technique for repairing articular cartilage defects in the knee. Despite reported improvements in pain, little is known about the recovery of knee biomechanics during walking gait.
A randomized controlled study design was used to investigate knee biomechanics during gait in 61 patients following matrix-induced autologous chondrocyte implantation, in conjunction with either 'accelerated' or 'traditional' approaches to post-operative weight-bearing rehabilitation. Gait analysis was performed at 3, 6 and 12months post-surgery in both patient groups, and two matched, unaffected control groups for comparison.
The spatiotemporal and ground reaction force parameters were similar between patient groups and their respective control groups at all time points. When compared with controls, both patient groups demonstrated significantly reduced knee extension moments up until, and including, 12months. The traditional group demonstrated a significantly reduced knee adduction moment at 3, 6 and 12months, and a significantly reduced knee flexion moment at 3months. There were no differences in these knee moments between the accelerated patient group and controls.
Overall, a higher level of gait dysfunction was observed in patients who underwent traditional rehabilitation. Future research is needed to investigate the recovery of normal gait following matrix-induced autologous chondrocyte implantation, and its effect on repair tissue development.

Toe-out/-in gait has been prescribed in reducing knee joint load to medial knee osteoarthritis patients. This study focused on the effects of toe-out/-in at different walking speeds on first peak knee...
Gait adaptations, including toe out gait, have been proposed as treatments for knee osteoarthritis. The clinical application of toe out gait, however, is unclear. This study aims to identify the chang...
Toe-in (TI) and toe-in with wider step width (TIW) gait modifications have successfully reduced the internal peak knee adduction moment (KAM) during level walking and stair ascent tasks, respectively,...
The increased use of gait analysis has raised the need for a better understanding of how walking speed and demographic variations influence asymptomatic gait. Previous analyses mainly reported relatio...
The purpose of this study was to compare lower extremity kinematics and kinetics between women with greater or lesser degrees of valgus knee alignment during gait. Nine women with greater valgus knee ...

Manner or style of walking.
An activity in which the body advances at a slow to moderate pace by moving the feet in a coordinated fashion. This includes recreational walking, walking for fitness, and competitive race-walking.
The rate at which steps are made while walking.
An instrument used to assess the results of rehabilitation from knee injuries, especially those requiring ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION. It measures recovery of knee joint function based on ACTIVITIES OF DAILY LIVING.
Impairment of the ability to coordinate the movements required for normal ambulation (WALKING) which may result from impairments of motor function or sensory feedback. This condition may be associated with BRAIN DISEASES (including CEREBELLAR DISEASES and BASAL GANGLIA DISEASES); SPINAL CORD DISEASES; or PERIPHERAL NERVOUS SYSTEM DISEASES.
An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and perioperative medicine. Anesthesiologists are physicians who provide medical care to patients in a wide variety of (usually acute) situations. ...
