Shoulder Collagen Injection Continues Effect 10 Months After Treatment...Confirmation of pain and function improvement at Bupyeong Himchan Hospital

Bupyeong Himchan Hospital evaluated 43 patients (22 males, 21 females, and an average age of 59.1 years) who received collagen injection treatment from September 2022 to June 2024. As a result, the pain score on the pain evaluation scale (VAS) decreased significantly from 8.6 points before the procedure to 2.2 points after 10.9 months. The pain evaluation scale selects the intensity of pain felt by the patient from 0 to 10, which means that the closer to 10, the greater the intensity of pain.
The UCLA Shoulder Score, which checks the overall health level of the shoulder, including shoulder pain, shoulder joint function, forward flexion (operational range), shoulder strength, and satisfaction, showed a significant improvement from 23.6 points before the procedure to 82.9 points after the procedure based on a perfect score of 100. The closer you get to 100, the better your shoulder is.
Rotator cuff rupture is a typical shoulder disease, and refers to a condition in which the rotator cuff, which is the shoulder tendon, is damaged due to degenerative changes or trauma. Treatment varies depending on the degree of rupture, and in the case of minor partial rupture, conservative treatment is generally performed to control pain and inflammation through medication, physical therapy, and extracorporeal shock waves.
Kim Tae-seop, Director of Orthopedic Surgery at Bupyeong Himchan Hospital, said "Even if the current partial rupture occurs, the probability of progressing to a full-layer rupture increases as the shoulder is used over time, so it is necessary to continuously undergo examination and follow-up observation."In particular, partial rupture with only a partial tear is likely to progress to full-layer rupture if the extent of the rupture exceeds 50% of the tendon thickness, so surgery should be considered."."
In particular, all-layer fractures with complete holes in the tendon should be surgically sutured as soon as possible. This is because if the size of the rupture increases, the probability of re-cracking is high even after surgery and shoulder strength can be weakened. If you miss the timing of surgery and your tendon is completely broken, artificial joint surgery is necessary.

Collagen injection treatment is a treatment that helps tissue regeneration by injecting collagen into damaged areas. Collagen is a major component of tendons and ligaments, and it has been used for a long time in plastic surgery because it is made harmless even when used in the human body. Approved by the Ministry of Food and Drug Safety, the risk of side effects is low, safe, and it is known to play a role in promoting the regeneration of damaged tissues due to the cell regeneration effect. As a minimally invasive treatment without incision, high-concentration collagen is directly injected into the rupture site using an endoscope, so the accuracy is high.
Director Shin Myung-jin "This investigation confirmed that patients who received collagen injection treatment maintained the effect of pain relief and shoulder function improvement even after about 10 months after surgery."The characteristics of the shoulder area that always moves make the condition worse once it ruptures, and collagen injection treatment is expected to be a useful treatment that can help regenerate tissue in the ruptured area."
