Hip arthroscopy is an outpatient procedure, which means you don’t have to stay overnight in the hospital. Instead, you arrive at the facility about an hour and a half before your surgery time. Our staff will check you in, listen to your heart and lungs and check your blood pressure, pulse, and temperature. We then start an IV to give you fluids and medications.
The anesthesia staff will discuss medications during surgery. Often, a general anesthetic is used in conjunction with a nerve block; the anesthetic puts you to sleep and the nerve block numbs your leg and hip during and after the surgery. The nerve block can last up to 24 hours after surgery, which helps manage initial discomfort caused by the surgery. Surgery time depends on how much repair needs to be done, but can last from one to three hours.
Once you’re fast asleep in the operating room, your hip is filled with saline, to expand your joint and make it easier for your surgeon to move surgical instruments and see tissues. To see inside your joint, your surgeon uses a special table that applies traction to separate your thighbone from its socket on the pelvis. Your foot is strapped into a boot that pulls your leg away from your pelvis, creating more space in the hip joint for surgical instruments.
Once there’s more space in your hip, your surgeon inserts an arthroscope, which is a tiny camera hooked up to a large computer screen. This magnifies the structures in your hip and allows your surgeon to view it.
Once your surgeon can see in the joint, they insert surgical instruments through another incision and repair damaged tissue. Often, multiple tiny incisions are made to get to different areas in your hip. While in your hip, your surgeon will usually fix any repairable damage they find, even if it was not expected before surgery.
Even MRIs can miss damage, but during an arthroscopy, your surgeon can see exactly what is problematic. A Physician Assistant (PA) often helps your surgeon throughout surgery and understands everything that was done.
After surgery, your surgeon will explain to your family what they found in the operating room and discuss any limitations you will have using your leg. You will be placed on crutches for the first day and remain on crutches until you regain full sensation in your hip. Before weaning off crutches, you should be able to bear full weight and walk comfortably. If a repair is needed or more intensive work was done, you may need to use crutches without bearing any weight on the leg for a few weeks.
Usually, your surgeon will have you just rest and recover for a few days after surgery. After that, you may take off the bulky surgical dressing from surgery and can shower.
Iit can be difficult to care for yourself after a hip arthroscopy, and you may find you need extra help. Your surgeon will tell your family if you have any specific restrictions after surgery.
After a hip arthroscopy, patients can expect to be meet with their surgeon or a Physician Assistant in 10-14 days to discuss what they found during surgery, what was done, and your recovery process.
Sometimes you can begin moving your hip and returning to activities on your own, as you feel able; other times you may require physical therapy.
It takes most patients one to two months before they’re back to their daily activities. For labral repairs, it can take up to three or four months before they’re back to their regular activities; however, it can take up to a year before they no longer notice hip pain.
Let's Discuss Your Options.
Hard Cartilage Damage and Chondroplasty
The thigh bone runs from the knee to the hip, with a ball-shaped head that fits neatly into a socket on the hip (acetabulum) to form the hip joint. These bony surfaces are covered by hard cartilage, which should ideally be smooth. Defects or flaps in the hard cartilage can cause a painful catch or click, limit the motion of your hip, and potentially damage the remaining healthy tissue in your hip.
Relatively small defects can sometimes be polished and smoothed out with gentle motion exercises like riding an exercise bike. For severe hard cartilage damage, surgical intervention may be required to remove unstable tissue flaps.
A hip chondroplasty uses a surgical instrument to remove the fraying or flapped hard cartilage and smooth down the remaining tissue. After this procedure, you are often placed on crutches for a few days and can wean from them gradually. Your surgeon will outline your post-surgery restrictions.
Labral Tears and Debridement vs. Repair
The thigh bone is a long bone running from the knee up to the hip, with a ball-shaped head that fits neatly into a socket on the hip (acetabulum) to form the hip joint. Inside the socket is a flexible rim of soft tissue called the labrum, which helps increase the stability of the hip. The labrum can fray or completely tear causing a flap of tissue to catch within the hip joint. This can cause pain, popping, and a feeling of instability in your hip.
This condition can be treated with an arthroscopy. If the damage to your labrum is minor, you may only need a debridement. A surgical instrument removes the fraying or flapped labrum and smooths down the remaining tissue. After a labral debridement, you are often placed on crutches and may begin to wean from them as you tolerate. For a completely torn labrum that requires repair, your surgeon will often use anchors made of a bone-like substance to sew your labrum back down to the bone. Over time, your body turns the anchor into your own bone. The number of sutures used during surgery will depend on the size and severity of your injury. After a labral repair, you will be given specific post-op instructions but you can expect to use crutches for up to 6 weeks. Your surgeon will tell your family exactly what your restrictions are after surgery.
Femoroacetabular Impingement (FAI) and Arthroscopic Femoroplasty
Inside the socket of the hip joint is a flexible rim of soft tissue called the labrum, which helps increase stability of the hip. Typically femoroacetabular impingement occurs because of a bony variation during developmental growth stages or from bone-spur formation later in life.
Femoral acetabular impingement (FAI) occurs when bone spurs form in the hip, causing abnormal motion within the hip joint and rubbing on the hip socket, which damages the hard cartilage on the bone or the soft tissue labrum.
There are different types of FAI depending on whether the bone spurs form on the thigh bone or on the hip socket. Any of these can cause pain, limited motion, and more damage to other structures in the hip. Femoral acetabular impingement typically affects the hip joint in young and middle-aged adults.
During an arthroscopic hip surgery, your surgeon will go in the hip joint and remove any bone spurs or excess bone. Your surgeon may use fluoroscopy, a special type of X-ray, to determine when they have restored an appropriate shape to the hip socket and/or thigh bone. Any damage to the surrounding soft tissues in your hip joint will also be debrided or cleaned up. Sometimes repair to the labrum is necessary.
After a femoroplasty, you will go home using crutches for the first few days and then can walk as tolerated. Your surgeon will outline your post-surgery restrictions.
The initial recovery for a femoroplasty is relatively short; however, the surface where the spur was removed can be sore for a few months following surgery, as it takes time for your body to develop a new hard covering on the bone. This procedure is typically very helpful for patients and bone spurs rarely return.
