Patients and methods: This multicenter, observational, noninterventional study included 98 patients (78 females, 20 males; mean age: 52.8±6.5 years; range, 40 to 64 years) who had Grade 1-3 knee OA between May 2022 and November 2022. The patients were prescribed the combination of hydrolyzed type 2 collagen, MSM, GS, and CS as a supplement for knee OA. The sachet form of the combined supplement containing 1250 mg hydrolyzed type 2 collagen, 750 mg MSM, 750 mg GS, and 400 mg CS was used once daily for two consecutive months. Patients were evaluated according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analog Scale (VAS)-pain, and Health Assessment Questionnaire (HAQ). Patients were scheduled to visit for follow-up four weeks (Visit 2) and eight weeks (Visit 3) after Visit 1 (baseline; day 0 of the study).
Results: For the VAS-pain, WOMAC, WOMAC-subscale, and HAQ scores, the differences in improvement between the three visits were significant (p<0.001 for all). The patient compliance with the supplement was a median of 96.77%, both for Visit 2 and Visit 3.
Conclusion: The combination of hydrolyzed type 2 collagen, MSM, GS, and CS for eight weeks in knee OA was considered an effective and safe nutritional supplement.
