In today’s reality, hip pain affects a large number of people to varying degrees in their daily lives and work, and some of them are advised by their doctors to undergo surgical treatments, mainly Total Hip Replacement (THR). The hip joint consists of two parts, a ball (femoral head) and a socket (acetabulum), the femoral head is at the upper end of the femur and the acetabulum is below the hip bone, it is a weight bearing joint. In a total hip replacement (i.e. artificial hip replacement), the doctor removes the head and socket and replaces them with a prosthesis of the femoral stem and socket. The Department of Orthopaedics at Quanzhou First Hospital has clinical experience with over 100 cases of hip replacement and follows a proven rehabilitation program after hip replacement surgery, which is beneficial to the patient’s recovery. The indications and rehabilitation of this surgery are briefly introduced. Hip joint injury can be caused by long-term weight bearing, sports, long-term alcohol consumption, hormones, etc. or secondary to joint trauma. It is not difficult to diagnose, and there are many ways to do it, but the right way is to be diagnosed and treated by a doctor or specialist. Although there are many ways to reduce pain, when you belong to the category of patients who cannot tolerate the pain of arthritis, when your daily life is obviously limited (such as not being able to sit in a chair, take a shower, change clothes, go to the toilet), and when neither the doctor nor the patient can solve the problem of pain and limitation of activities by non-surgical methods, surgery is the best way. Now let’s talk about the indications for total hip replacement. Medically speaking, the indications for artificial hip replacement are: 1) old femoral neck fracture; 2) ischemic necrosis of the femoral head; 3) degenerative osteoarthritis; 4) rheumatoid arthritis and arthropathy of ankylosing spondylitis; 5) ankylosis of the hip joint; 6) arthroplasty failure cases; 7) joint destruction caused by bone tumors; and 8) traumatic osteoarthropathy. The patient must meet the following four criteria for surgical treatment: 1, the patient’s joint surface destruction has clear X-ray or CT imaging changes; 2, there is moderate to severe persistent pain; 3, long-term conservative treatment can not be substantially improved; 4, the patient’s joint function is significantly affected. For artificial hip replacement, there are few contraindications, mainly local or systemic infection, extremely serious cardiopulmonary and other systemic diseases. Excessive obesity is a relative contraindication to surgery. In the past, it was believed that the optimal age for total hip replacement was over 50 years old, but nowadays there is a greater tendency to improve the patient’s ability to work and live, and to improve the quality of life, while the age factor is not the main determinant of surgery, and patients in their 20s have been repeatedly reported. Current statistics show that the 15-year success rate for joint replacement is over 95%. Once you decide to undergo surgery, you will be hospitalized for about 2-3 weeks, during which time the medical staff will do everything they can to help you. Rehabilitation after surgery is a concern for every patient. Post-operative pain, the original pain after surgery has disappeared or significantly reduced, but the pain caused by the surgery to continue for a period of time, can be appropriate application of painkillers. One of the most important things a patient wants to do after surgery is to sleep, so the doctor advises well-meaning visitors to postpone coming back for 1-2 days. For the first three days after surgery, the patient has to lie down to urinate and defecate, and sometimes it is necessary to insert a catheter, so the corresponding preoperative training can help. At the same time, the affected limbs can not be crossed to the opposite side, after surgery can be placed on a pillow in the middle of the two legs to keep the lower limbs adduction, not excessive external rotation of the lower limbs, do not get up excessive flexion of the body, bending over no more than 90, sitting up flexion of the body does not exceed 90, the affected limbs of the knee joints can not be lifted more than the hip joints, can not be cross legged. It should be noted that although the sofa is good, but can lead to joint dislocation. Functional exercise is the key to your early recovery. You should insist on more than 3 times a day, 30-45 minutes each time, and never stop for a day. You can do the following exercises: move the ankle up and down; lie down and gently bend the knee and gently externally rotate the hip at the same time; thereafter lie down and lift the leg. From lying to sit on the edge of the bed, and then you can walk on the ground, the beginning of you need to use crutches or walker, abandon the cane walking time should depend on the specific circumstances, generally the first two canes, and then a single cane, and then abandon the cane. You can finally go out for a walk, note: the healthy limbs first on the stairs, downstairs when the affected limbs first down (commonly known as: good legs to heaven, bad legs to hell), when you can walk for the first time alone to reach a destination, it is really a thing to be celebrated. In addition, swimming and bicycling exercises are useful. Six weeks after the surgery, when you are able to walk on your own, you will need to see your doctor for a follow-up appointment so that he or she can adjust your rehabilitation program to your progress. Regular follow-up appointments will be required in the future.
