Subjects who reported knee pain of 5 on an 11-point Likert scale while performing a Single-Leg-Step-Down (SLSD) test were randomized to receive placebo (PLA, n=48), or Undenatured Collagen (n=48) for 24 weeks. Joint mobility was measured from the daily step number. Joint discomfort was evaluated using the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire, duration of pain during sporting activities and number of steps to reach defined pain levels during the SLSD test. A sub-analysis by gender showed a higher number of daily steps in males from the Undenature.. View More»
