This study looked at knee joint biomechanics in a young, healthy population with no activity restrictions, with a focus on energy storage and return (ESAR)  prostheses. The authors recognise that the study had a small sample size, and discuss potential sources of error for their data collection, but are confident about the clinical application of their findings.

KEY POINTS: KNEE BIOMECHANICS FOR TRANSTIBIAL AMPUTEES

• There is a high prevalence of joint pain and osteoarthritis (OA) in unilateral transtibial and transfemoral amputee populations.
• Transtibial amputees are more likely to develop OA in the intact knee.

Abnormal gait biomechanics include asymmetric ground reaction forces, muscle activation patterns, and knee joint kinetics between limbs.
