The findings of this study show that the minimally invasive technique of percutaneous hamstring tenotomy is effective in improving knee extension at initial contact, increased velocity, increased stride length, improved overall gait as indicated by a decrease in a 16 variable multivariate index (Gillette Gait Index), increased peak knee extension in stance, reduced plantar flexion at initial contact , decreased popliteal angle and increased anterior pelvic tilt for individuals with CP for a short term. All these improvements are maintained in the long term, but the last one.
