Atelocollagen ＆ Hyaluronic Acid Correlation With Enhancement of Rotator Cuff Healing: Synergistic Effect?

Atelocollagen ＆ Hyaluronic Acid Correlation With Enhancement of Rotator Cuff Healing: Synergistic Effect? 2-Year Results of a Randomized Controlled Trial

The purpose of this study is to analyze the correlation between the synergistic effects of atelocollagen and hyaluronic acid (HA) in enhancing rotator cuff healing postoperatively in patients undergoing rotator cuff repair surgery.The main questions it aims to answer are:

• Does atelo Collagen aid in the rotator cuff repair healing process?
• Does hyaluronic acid (HA) aid in the rotator cuff repair healing process?
• Does the combined use of atelo collagen and HA in the rotator cuff repair healing process have a synergistic effect?

The researchers will compare the use of atelo collagen and HA alone with no treatment to determine their effectiveness in rotator cuff healing.

Participants will:

• receive injections of atelo collagen or HA, either alone or in combination, during arthroscopic rotator cuff repair.
• visit the clinic for medical checkups and tests every 3 months, 6 months, 1 year, and 2 years.

Inclusion Criteria:

• Age between 40 and 75 years
• Scheduled for arthroscopic surgery after an MRI confirmed a diagnosis of rotator cuff tear
• Willing to participate and provide informed consent

Exclusion Criteria:

• Previous surgery on the affected shoulder
• Severe glenohumeral arthritis (Hamada grade ≥ 3)
• Neurological disorder affecting shoulder function
• Massive rotator cuff tear (Tear size ≥ 5 cm)
