Begin the preoperative preparations by gathering all the necessary materials. Then proceed to check the basic information of each patient, including name, age, and the affected shoulder. Once the patient assumes a sitting position, fully expose the affected shoulder and mark the obvious tenderness points on the shoulder.
Then, pour type two skin disinfectant on cotton balls, and with those, disinfect the affected area in circular motions, starting from about 15 centimeters around each marked point, and gradually reducing the diameter. Next, load five milliliters of 2%lidocaine into a 10 milliliter syringe with a 22 gauge needle. Then, load five milliliters of sterile water into the same syringe to prepare 10 milliliters of 1%lidocaine working solution.
Replace the 22 gauge needle with a 25 gauge needle. While wearing sterile gloves on the left hand, hold the syringe in the right hand, insert the needle into a marked point, and ensure no blood enters the syringe after suction. Perpendicularly, inject one to two milliliters of 1%lidocaine working solution at the marked point.
To perform the small needle knife insertion, hold the small needle in the right hand while wearing sterile gloves. Rapidly insert the small needle knife into the lidocaine injection site perpendicularly, maintaining a depth of about one to three centimeters. Then, perform the three step manipulation, beginning with the longitudinal incision, followed by stripping, and finally releasing the adhesion.
Withdraw the needle when there is a feeling of looseness under the knife. Using a dry, sterile dressing block, press the injection site for one minute. Then cover the operating area with a sterile self-adhesive dressing.
After assisting the patient in dressing properly, ask the patient to sit still for about 15 minutes before leaving the operating room to avoid postoperative discomfort. After the small needle knife therapy, the visual analog score was significantly lower in the treatment group than in the control group. The Constant and Murley score was significantly higher in the treatment group than in the control group.
