Is minimally invasive needle-knife therapy effective for treating adhesive capsulitis (frozen shoulder)?

　　The small needle-knife technique integrates the advantages of current clinical treatments and has become a widely adopted new approach for treating periarthritis of the shoulder (frozen shoulder). Conventional treatment for periarthritis of the shoulder primarily focuses on anti-inflammatory and analgesic therapy; acupuncture can also be effective, but it typically requires a prolonged treatment course accompanied by discomfort—many patients are therefore unable to adhere to the full regimen. So, how effective is the small needle-knife technique for treating periarthritis of the shoulder?

　　How Effective Is the Small Needle-Knife Technique for Treating Periarthritis of the Shoulder?

　　The small needle-knife technique can play a beneficial role in managing periarthritis of the shoulder. During the procedure, the needle-knife is inserted into the affected periarticular tissues of the shoulder, where it performs precise cutting to release local fascial tension and loosen the joint capsule. This often helps alleviate adhesions within the joint, relieve compression of surrounding blood vessels and nerves caused by the pathology, reduce inflammation, and improve local microcirculation. However, for severe cases of adhesive capsulitis or bursitis with extensive fibrotic adhesions, the small needle-knife alone may not achieve complete release. In such instances, manual release under general anesthesia or arthroscopic-assisted release is recommended.

　　After undergoing small needle-knife treatment for periarthritis of the shoulder, maintain cleanliness at the wound site and extend compression time to ensure hemostasis. Typically, compression may be removed once bleeding has ceased; alternatively, a cotton ball may be placed directly over the needle-knife puncture site and secured with a pressure bandage. Patients are advised not to leave the hospital or clinic immediately after treatment but to remain for observation for 5–10 minutes before departure. As a minimally invasive procedure, the small needle-knife technique carries a low risk of adverse reactions. Should any discomfort or unexpected symptoms arise, patients should promptly contact their attending physician or seek medical attention at a hospital.

　　In daily life, maintain a regular, balanced diet—avoid spicy, stimulating, or excessively rich foods, and refrain from binge eating or staying up late. We hope this information proves helpful.
