This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether collagen peptides — a supplement made from broken-down collagen protein — can help your knee heal better after knee replacement surgery. Researchers want to see if taking this supplement daily for 6 months improves how well your new knee works, reduces pain, and helps your surgical wound heal faster. About 44 people will participate, and half will receive the actual collagen peptides while the other half will receive a placebo (inactive substance) so researchers can compare the results fairly.
After knee replacement surgery, your body needs to rebuild and repair the tissues around your new joint. While surgery is effective, recovery can be slow and challenging. This trial exists to find out whether adding collagen supplementation might give your body the extra building blocks it needs to heal faster and stronger, potentially improving your function and reducing pain during recovery.

You would start the study about 2 months before your scheduled knee replacement surgery. Before surgery, you'll have a baseline visit where researchers will take measurements of your knee function, overall health, and body composition, plus collect blood samples and bone density scans. During your surgery, researchers will also collect small tissue samples that would normally be discarded. After surgery, you'll take either collagen peptide or placebo powder (10 grams daily) for 24 weeks while attending your regular physical therapy. You'll have follow-up visits at weeks 4, 8, 12, 16, 20, and 24 to track your recovery, pain, and how well your knee is working.
