Lateral epicondylitis, also known as Tennis Elbow, causes pain and limits daily activities for many people. This research compares two treatment methods to see which might be better for relieving symptoms. The study focuses on adults aged 18 to 70 who have had chronic elbow pain for at least six months and have not improved after other treatments. Participants will be randomly assigned to one of two treatments: Ultrasound-guided Percutaneous Tenotomy or Open Surgical Debridement. The Tenex procedure uses a special needle guided by ultrasound to remove damaged tissue with ultrasonic energy in a doctor's office under local anesthesia. The open surgical debridement involves a surgeon making an incision to remove damaged tendon tissue under anesthesia in a surgical center. Throughout the study, participants will have follow-up visits at 3 weeks, 6 weeks, 3 months, 6 months, and 12 months after treatment to check progress. They will also complete questionnaires about their symptoms and function during these visits. Researchers will compare complications and functional outcomes between the two treatments to better understand their effects.

Researchers are evaluating the effect of preoperative Cryoneurolysis on managing postoperative pain and opioid use in patients undergoing autograft anterior cruciate ligament (ACL) reconstruction, a surgery that creates a new ACL using the patient's own tendon. Cryoneurolysis involves applying extreme cold to specific nerves to reduce or eliminate pain. The study compares standard care alone to standard care plus Cryoneurolysis to better understand its impact on pain relief after surgery. Participants will be randomly assigned to either receive standard care only or standard care plus Cryoneurolysis treatment to their surgical knee 7 to 10 days before surgery. The Cryoneurolysis targets specific nerves around the knee, including the anterior femoral cutaneous nerve, supra-patellar branch of the saphenous nerve, and infra-patellar branch of the saphenous nerve. All participants will undergo autograft ACL reconstruction and receive typical preoperative and postoperative pain management. During the 12-week study period, participants will bring their leftover postoperative pain medications to follow-up visits for review. They will also complete surveys about their knee activity, function, and symptoms at these appointments. Researchers will measure opioid use after surgery at 1 week, 6 weeks, and 12 weeks to assess pain management effectiveness. The study lasts until the 12-week postoperative follow-up is completed.
