Reconstruction of proximal hamstring ruptures restores joint biomechanics during various walking conditions.
Purpose: We aimed to examine the functional outcome in different walking conditions in elderly adults who underwent surgical repair after a non-contact hamstring injury. Our objective was to compare lower limb kinematics and kinetics over the entire gait cycle between the injured and contralateral leg in overground and level and uphill treadmill walking.
Methods: 12 patients (mean ± SD, age: 65 ± 9 years; body mass index: 30 ± 6 kg/m2) walked at self-selected speed in overground (0% slope) and treadmill conditions (0% and 10% slope). We measured spatiotemporal parameters, joint angles (normalised to gait cycle) and joint moments (normalised to stance phase) of the hip, knee and ankle. Data between sides were compared using paired sample t-tests (p< 0.05) and continuous 95% confidence intervals of the paired difference between trajectories.
Results: Patients walked at an average speed of 1.31 ± 0.26 m/second overground and 0.92 ± 0.31 m/second on the treadmill. Spatiotemporal parameters were comparable between the injured and contralateral leg (p> 0.05). Joint kinematic and joint kinetic trajectories were comparable between sides for all walking conditions.
Conclusions: Refixation of the proximal hamstring tendons resulted in comparable ambulatory mechanics at least 1 year after surgery in the injured leg and the contralateral leg, which were all within the range of normative values reported in the literature. These results complement our previous findings on hamstring repair in terms of clinical outcomes and muscle strength and support that surgical repair achieves good functional outcomes in terms of ambulation in an elderly population.
期刊介绍:
HIP International is the official journal of the European Hip Society. It is the only international, peer-reviewed, bi-monthly journal dedicated to diseases of the hip. HIP International considers contributions relating to hip surgery, traumatology of the hip, prosthetic surgery, biomechanics, and basic sciences relating to the hip. HIP International invites reviews from leading specialists with the aim of informing its readers of current evidence-based best practice.
The journal also publishes supplements containing proceedings of symposia, special meetings or articles of special educational merit.
HIP International is divided into six independent sections led by editors of the highest scientific merit. These sections are:
• Biomaterials
• Biomechanics
• Conservative Hip Surgery
• Paediatrics
• Primary and Revision Hip Arthroplasty
• Traumatology
