Brief Summary
The primary objective of this study is to confirm the superiority of intra-articular collagen injection in patients with knee joint pain compared to the control group. 100mm VAS is used to measure the pain of the subjects 24 weeks after the procedure.

Outcome Measures
Primary Outcomes (1)
100 mm Visual Analogue Score (VAS)
100 mm Visual Analogue Score (VAS) is measurement instrument for subjective characteristics or attitudes that cannot be directly measured. In this trial, it is used for quantification of the pain on the defected knee. The VAS score of the investigational group and the control group at 24 weeks after injection will be compared and analyzed. Score range: 0 \~ 100 mm Higher score indicates the worse outcome. In this case, participant is feeling more pain.
24 weeks after injection
Secondary Outcomes (6)
WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index )
at the screening visit, 4, 12, and 24 weeks after injection
36-ltem Short-Form Health Survey (SF-36)
at the screening visit, 4, 12, and 24 weeks after injection
Number of Patients Who Are Satisfied With Improvement Assessed by Self-evaluation
at 4, 12, and 24 weeks after injection
Number of Patients With Satisfying Improvement Assessed by Physicians
at 4, 12, and 24 weeks after injection

Study Arms (2)
CartiZol, collagen injection
EXPERIMENTALTheir eligibility to participate in the study is checked, and they are randomized into the intra-articular collagen injection group based on a randomization table.
Normal Saline injection
PLACEBO COMPARATORTheir eligibility to participate in the study is checked, and they are randomized into the (placebo) injection group based on a randomization table.
Interventions
The product, CartiZol, which contains absorbable collagen, is applied on the cartilage defect to stimulate the neovasculization and cell penetration and to assist the natural wound healing process. It supplements the defective or damaged cartilage. Place the needle on the tip of the syringe and inject the product into the articular cavity.
1. Supplementation of fluid and electrolytes (sodium or chlorine deficiency) 2. Diluent for injection solution Place the needle on the tip of the syringe and inject the product into the articular cavity.
Eligibility Criteria
You may qualify if:
- Adult patients aged 19 or older
- Patients with knee joint pain due to chondromalacia, osteoarthritis (OA), or traumatic arthritis (TA)
- Patients with 3 or lower score in the Kellgren-Lawrence grade
- Patients with 40 mm or higher scores in the 100 mm VAS pain scale
- Patients without significant pathological tests at their screening visit
- Patients whose medication is confirmed within one week from their study enrolment and who agreed to maintain the medication dose during the study period if they need to keep taking it
- When combination drugs are administered, considering the period of the drugs remaining in the body, patients who take the drugs stably for 2 weeks prior to participating in the trial (based on the screening, if it is confirmed that the patients took the drugs stably for 1 week prior to the screening, at the enrollment for injection, it should be assessed again, and the patients who are confirmed to have taken the drugs stably for 2 weeks prior to the trial could be registered).
- Patients who, after taking drugs for anesthetic purposes (provided to the subject after the injection) within one week after the intra-articular injection, agreed to take anti-inflammatory agents for no more than 5 consecutive days and for no more than 10 days in a month, and could stop taking the drugs within 2 days after the next visit even if the pain in the observation site becomes severe and thus additional drugs are required.
- Patients who agreed to use only the non-drug treatments (i.e., physiotherapy, osteopathy, and chiropractic therapy) allowed by the study investigators (Acupuncture is not allowed.)
- Patients who agreed to receive the injection only in one knee when they feel pain on both knees (The other knee can be treated with prescribed drugs, but articular injections are not allowed.)
- Patients or their representative (for adults) who agreed to participate in the study and signed the informed consent form
You may not qualify if:
- Patients or their family members with a history of or an ongoing autoimmune disease
- Patients with a history of anaphylactic response
- Patients with hypersensitivity to grafting materials
- Patients with hypersensitivity to porcine protein
- Patient with grade 4 in the Kellgren-Lawrence grade
- Patients with severe effusion
- Patients who were injured severely or received injection in their affected knee within six months, which would make evaluation of the knee difficult
- Patients with inflammatory arthritis such as rheumatoid arthritis, rupus arthrosis, or psoriatic arthritis
- Patients who have gout or calcium pyrophosphate (pseudogout) disease that started within six months from the screening visit
- Patients with a history of radiation therapy or cancer treatment within two years
- Patients with diabetes
- Patients with an infection that required hospitalization for antibiotics or the administration of antiseptic agents
- Patients who have been undergoing adrenocortical hormone therapy
- Patients with liver, heart, or kidney disease
- Patients who had been infected with a virus
