As a Class One advanced all-around gymnast in college Marneen's right ankle was injured badly from a fall off the balance beam. She underwent an ankle reconstruction surgery where a calf's tendon was inserted into the ankle in place of the torn ligaments. She performed 15 years of highly dangerous stunt work and stunt acting work with the calf's tendon in her ankle, a tendon that remains in place today. Marneen's calf's tendon has outlived the use of doctors using calf's tendons in place of human ligaments in ankle reconstruction surgeries, today they use ropes.
