1.What kind of surgery is hip arthroscopy? Hip arthroscopy is a minimally invasive technique that uses arthroscopic instruments for examination and surgery. Arthroscopy is a minimally invasive means of examination, which is able to see the injury and determine the location and extent of the injury, and at the same time, arthroscopic instruments can directly reach the site of the injury and perform minimally invasive surgical repair. 2.How big is the incision of hip arthroscopy, is it minimally invasive, and does it affect the aesthetics? How is the postoperative pain? Hip arthroscopy is a minimally invasive surgical technique, with 2-3 tiny incisions of about 1cm (width of the little finger), which is much less traumatic than the traditional large-incision open surgery. The post-operative pain is much lighter (only a small amount of oral painkillers can be used), the pain is significantly reduced in 1-2 weeks, and the recovery is much quicker (getting out of the bed on crutches in 2-3 days). 3.What conditions require hip arthroscopy? Is there any requirement for the patient’s age? Acetabular labral injury, hip impingement syndrome, hip free body, etc., suitable for hip arthroscopy and the efficacy of the surgery. Recurrent unexplained hip pain, recurrent joint effusion, synovial lesions, joint infections, etc. can also be resolved by hip arthroscopy. Age is not a contraindication. The most common age of patients is 20-40 years old, and young sports enthusiasts are the main surgical population. Moderate to severe hip dysplasia, obvious osteoarthritis, etc., with poor long-term outcome, arthroscopic surgery is generally not recommended. 4.What examinations are needed before hip arthroscopy? Pre-operative examinations vary according to the condition and seek to make a clear diagnosis. If hip impingement syndrome is considered, appropriate special position X-rays (pelvic orthostasis + Dunn position), and single hip MRI should be done. It is not recommended to check in the local hospital, the special position examination needs experienced doctors and radiologists to cooperate to complete, and magnetic resonance and CT these examinations are different grades, the examination in the local hospital can only be used as a reference. 5.Hip impingement, glenoid labral injury is suture repair or resection? Acetabular labral and cartilage injury is an important manifestation of the hip impingement sign and the cause of pain, and it is also the main surgical site. Suture repair optimally preserves labral tissue and slows joint wear and degeneration. Labral cleaning and resection, despite short-term pain relief, may accelerate joint wear and arthritis in the long run. 6. After hip arthroscopy to suture the labrum, is the metal nail removed? What are the effects on the future? The most commonly used titanium alloy anchor nail for hip arthroscopy is the titanium alloy anchor nail with wire, which can be permanently embedded in the bone and rarely rejected, so it does not need to be removed. Unless the anchor is loosened and dislocated due to trauma, joint wear and tear, it needs to be removed. Of course, there are also resorbable anchor nails made of PEEK material. 7. What are the results of hip arthroscopy? The efficacy of hip arthroscopy depends on the diagnosis of the condition, the experience of the surgeon, the rehabilitation training and many other aspects. You need to fully communicate with your physician before surgery. Patients with clear diagnosis, suitable for hip arthroscopy, and experienced minimally invasive arthroscopic surgeon’s treatment, more than 80-90% of patients are satisfied with the surgical results. 8. Are there risks and complications associated with hip arthroscopy? Do take a train, airplane, anything has risk, but not because of the risk will not go out, surgery is the same. Hip arthroscopy is a mature surgical technique, but there are still risks and complications: (1) nerve paralysis (physicians try to avoid, but still a few patients appear, most of the 2 weeks or so to recover or alleviate) (2) cartilage and the hip joint structure damage (3) vascular damage Experienced doctors can basically eliminate this kind of complication (<1%). (4) Joint instability (3) Heterotopic ossification joint stiffness Rare, can be prevented by oral medication (5) Fascial compartment syndrome caused by infiltration of perfusion fluid into the posterior abdominal cavity, pelvis, or thigh Rarely reported as an act of God. 9, hip arthroscopy rehabilitation, how long crutches out of bed? After hip arthroscopy, systematic rehabilitation is needed, and the time varies with different conditions and surgical methods. Get out of bed on crutches 2-3 days after surgery, <10% of toe exertion in 1-2 weeks after surgery, 30% of toe exertion in 3-4 weeks after surgery, 50% of toe exertion in 5-6 weeks, 10. How long will I be free to walk after hip arthroscopy? How long can I run and exercise? Gradually abandon crutches and walk freely with full weight bearing at 6-8 weeks after surgery, but do not walk too much distance at the beginning. In 2-3 months after surgery, you can basically walk freely without pain, and there is no restriction on bicycling and driving. 4-6 months after surgery, you can basically resume sports.
