Effect of KAATSU training on thigh muscle size and safety for a patient with knee meniscectomy over 3 years

抄録

[Objective] It is well known that knee meniscectomy is one of the major knee surgeries, which induces thigh muscle atrophy. However, it is unclear whether thigh muscle size after knee meniscectomy can be improved with KAATSU training. We examined effect of KAATSU training on thigh muscle size and safety for a patient with knee meniscectomy.

[Methods] The patient was a 57-year-old woman (standing height 159 cm and body weight 52 kg). The KAATSU training composed of 7 types of resistance exercise and one type of cycling exercise was provided for a total of 125 sessions over approximately 3 years. Transverse scans were carried out for mid-thigh length. Thigh muscle cross-sectional area (CSA) in affected-leg and unaffected-leg was measured by the CT scan before, 63 weeks, and 152 weeks after the training.

[Results] Thigh muscle CSA was highly increased for affected-leg, and the attained level was exactly similar for both legs after the 152 weeks training period.

[Conclusion] The long-term KAATSU exercises were a highly safe and effective training method for a patient with knee meniscectomy.
