Efficacy of Bioactive Collagen Peptide Compared to Glucosamine and Chondroitin Sulphate in Grade I-III Knee Osteoarthritis

Brief Summary The goal of this clinical trial is to learn whether bioactive collagen peptide works as well as glucosamine and chondroitin sulphate for improving pain, stiffness, physical function, and quality of life in adults with mild to moderate knee osteoarthritis (Kellgren-Lawrence grades I to III). The main questions it aims to answer are: Does bioactive collagen peptide improve knee pain, stiffness, and physical function over 12 weeks? Does bioactive collagen peptide improve health-related quality of life? Is bioactive collagen peptide as safe and effective as glucosamine and chondroitin sulphate for treating knee osteoarthritis? Researchers will compare bioactive collagen peptide with glucosamine and chondroitin sulphate to determine whether one treatment provides greater improvement in symptoms and quality of life. Participants will: Be randomly assigned to receive either bioactive collagen peptide once daily or glucosamine and chondroitin sulphate twice daily for 12 weeks. Attend study visits at the start of the study and again at 6 and 12 weeks. Complete questionnaires about their knee pain, stiffness, physical function, and overall health-related quality of life at each visit. Be monitored for treatment adherence, use of rescue pain medication, and any side effects throughout the study. The information from this study may help healthcare providers better understand whether bioactive collagen peptide is an effective and safe non-surgical treatment option for people with symptomatic knee osteoarthritis.

Targeted Rehabilitation Versus Standard Care in Managing Medial Knee Pain and Varus Malalignment: A Randomized Control Trial

Medial knee pain with varus alignment is common in active adults and is associated with increased medial joint loading, cartilage loss, and progression of knee osteoarthritis. Conventional rehabilitation typically emphasizes quadriceps strengthening and general physiotherapy, which may reduce pain and improve function but often has limited effect on abnormal frontal-plane loading and alignment in individuals with varus deformity. Targeted neuromuscular and alignment-focused exercise programs that emphasize hip and lower-limb muscle control may better address underlying biomechanical contributors to medial knee loading. This randomized controlled trial will compare a traditional/conventional physical therapy program with a specific, alignment-focused exercise program in active adults aged 30-55 years who have medial knee pain, mild to moderate varus deformity, and Kellgren-Lawrence grade 1-3 knee osteoarthritis. Approximately 80 participants will be recruited from an outpatient setting and randomized (1:1) to receive either traditional rehabilitation or a targeted exercise protocol focusing on hip adductors and internal rotators. The supervised intervention will last 6 weeks, with follow-up assessments at 12 weeks, 6 months, and 1 year. The primary outcome is the Oxford Knee Score, with secondary outcomes including lower-extremity function, pain, quality of life, muscle strength, and radiographic alignment.
