The institute investigated the condition of 39 patients who received collagen injection treatment for partial rupture of the rotator cuff since December last year after an average of 6.7 months. According to a survey of five items (UCLA Shoulder Score) such as ▲ shoulder pain level ▲ shoulder joint function ▲ forward flexion (operational range) ▲ shoulder strength ▲ satisfaction, the total score improved by 54% from 19.9 points before the procedure to 30.7 points after the procedure. In general, a total score of 29 or more can be evaluated as having good shoulder health.
The rotator cuff rupture is the most representative shoulder disease, and the rotator cuff, which is the shoulder tendon, is damaged due to degenerative changes such as aging or trauma. Depending on the degree of rupture, it is divided into a full-layer rupture with a complete hole in the tendon and a partial rupture with only a partial tear, and even a minor level of partial rupture can be transferred to full-layer rupture over time, so appropriate treatment is needed early.
Choi Kyung-won, director of Himchan Hospital's Shoulder Clinic (Orthopedic surgeon), said "In the past, symptoms such as pain or inflammation were controlled during partial rupture of the rotator cuff, but surgery was performed when the rupture progressed to a certain part or more."In the case of collagen injection treatment, which is a non-surgical treatment, the tissue at the rupture site is regenerated, so the partial rupture can be suppressed from progressing to full-layer rupture."
◇Treat the partial rupture quickly to prevent the full-layer rupture from proceeding
The rotator cuff consists of four muscles and tendons, and if one or more of them ruptures, shoulder pain may be constantly felt and arm movement may be limited. If the range of partial rupture exceeds 50% of the thickness of the tendon, it is likely to progress to full-layer rupture, so surgery should be considered. In the case of full-layer rupture, it is important to suture it surgically as soon as possible, and if the size of the rupture gradually increases, the probability of re-destruction is high and shoulder strength can be weakened even after surgery. If you miss the timing of the surgery and the tendon is completely broken, making it difficult to return to its original state, you should undergo artificial joint surgery. Therefore, it is recommended to avoid progressing to full-layer rupture through appropriate treatment and management from the partial rupture stage.
Recently, collagen injection treatment, which is effective for partial rupture of rotator cuff, has attracted attention. Collagen injection treatment is a treatment that increases the regenerative effect of damaged tissue by injecting collagen into the lesion area. Collagen is a component of tendons and ligaments that makes it harmless to use in the human body, so it has been used in plastic surgery for a long time. With the approval of the Ministry of Food and Drug Safety, it is safe, has a low risk of side effects, and has excellent cell regeneration effect, so it plays a role in promoting the regeneration of damaged tissues.
◇39% of pain and 42% of function improvement after collagen injection, 90% of patient satisfaction
In fact, based on the UCLA Shoulder Score, the Institute of Arthology at Himchan Hospital conducted a survey at an average of 6.7 months after collagen injection treatment, and found that shoulder pain, function, and muscle strength improved remarkably. Comparing the average figure by item, the degree of pain was 5.9 to 8.2 (39% improvement), the function was 6.0 to 8.5 (42% improvement), the anterior flexion was 3.8 to 4.7 (24% improvement), and the shoulder strength was 4.1 to 4.9 (20% improvement). The post-procedure satisfaction level was 4.5 points, with 90% of patients saying 'satisfied'. The average age of 39 patients (16 males and 23 females) surveyed is 63.
In particular, comparing the average scores of the UCLA Shoulder Score 3.2 weeks after the collagen injection treatment and 6.7 months after the same patient group, it can be seen that the improvement effect is maintained after 6 months at 30.1 and 30.7, respectively. By detailed item, the degree of pain was 7.8 and 8.2 points, the function was 8.2 and 8.5 points, the satisfaction was 4.9 and 4.5 points, the anterior flexion was 4.5 and 4.7 points, and the shoulder strength was 4.7 and 4.9 points.
The effect of collagen injection treatment is also confirmed through other research results. According to a paper published in the U.S. Journal of Sports Medicine in 2020 by a research team at Catholic University School of Medicine, MRI examinations of patients with partial rupture of the rotator cuff showed that the partial rupture of the rotator cuff was recovered in 36.7% of the patient group who injected 1 ml of Atelocollagen.
`Since the shoulder is always in motion, the golden time of treatment is very important because once the rotator cuff ruptures, it is likely to progress to full-layer rupture,' said Yoo Soon-yong, director of Himchan Hospital's shoulder clinic. `If collagen injection treatment is performed in a timely manner when partial rupture occurs, pain relief and shoulder function recovery can be expected without reaching surgery.'
