Ultrasound-guided Needle Percutaneous Electrolysis With Therapeutic Exercise in Femoroacetabular Impingement Syndrome

Hip pain in the front of the hip is common and can make daily activities and sports difficult. One frequent cause is femoroacetabular impingement, also known as hip impingement. This clinical trial is studying whether adding ultrasound-guided percutaneous electrolysis - a minimally invasive physiotherapy technique that uses a fine needle and a small electrical current - to a program of specific exercises works better than doing the exercises alone. Participants will be randomly assigned to one of two groups: * One group will receive two sessions of percutaneous electrolysis plus a home exercise program. * The other group will follow the same home exercise program without percutaneous electrolysis. The study will last five weeks. Researchers will measure pain, hip movement, and hip function at the beginning, after one week, and after four weeks. They will also record any side effects. The main goal is to find out if adding percutaneous electrolysis helps reduce hip pain and improve function more than exercise alone. This pilot study will help determine if this technique could be a safe and effective non-surgical treatment option for people with pain in the front of the hip.
