Hip Arthroscopy

Hip arthroscopy is a minimally invasive surgical procedure used to diagnose and treat various painful conditions inside or around the hip joint. It involves making small incisions to insert a tiny camera and specialized tools, allowing surgeons to view and repair damaged tissues without a large open cut. This approach often leads to less pain and a quicker recovery compared to traditional open surgery.

What is Hip Arthroscopy?

Hip arthroscopy is a type of minimally invasive surgery where a surgeon uses a small camera, called an arthroscope, to look inside your hip joint. This procedure allows them to diagnose and treat problems with the bones, cartilage, and other soft tissues without making a large incision.

During hip arthroscopy, the surgeon makes a few small cuts, usually about a quarter-inch long, around your hip. Through these small openings, they insert the arthroscope, which sends images to a video monitor. This magnified view helps the surgeon see the inside of your joint clearly. Tiny surgical instruments are then inserted through other small incisions. These tools allow the surgeon to repair or remove damaged tissue. Because the incisions are small, hip arthroscopy is often an outpatient procedure, meaning you can usually go home the same day.

Why it's done

Hip arthroscopy is performed to address various painful hip conditions that have not improved with non-surgical treatments like rest, medication, or physical therapy. It can help diagnose and treat issues such as torn cartilage, bone spurs, or inflammation within the hip joint.

This procedure is commonly done to treat conditions like femoroacetabular impingement (FAI), where extra bone grows along one or both of the bones that form the hip joint, causing them to rub together. It is also frequently used for labral tears, which are injuries to the ring of cartilage (the labrum) that lines the hip socket. Other reasons for hip arthroscopy include removing loose pieces of bone or cartilage, treating snapping hip syndrome, addressing certain types of hip dysplasia, or repairing inflamed joint lining (synovitis). The goal is to reduce pain, improve hip function, and prevent further damage to the joint.

How to prepare

Preparing for hip arthroscopy involves several steps to ensure a safe and successful procedure. You will need to discuss your complete medical history, including all medications and allergies, with your doctor and follow specific instructions regarding food, drink, and activity before surgery.

Your doctor will likely order pre-surgical tests, such as blood tests, an electrocardiogram (EKG), or X-rays, to ensure you are healthy enough for surgery. It's crucial to tell your surgeon about all medications you take, including over-the-counter drugs, supplements, and herbal remedies. You may need to stop taking certain medications, especially blood thinners, for a period before the procedure. You will receive instructions about when to stop eating and drinking before surgery, typically after midnight the night before. It's also important to arrange for someone to drive you home after the procedure and to help you during the first day or two of recovery, as you will likely be groggy from anesthesia and may have limited mobility.

What happens during

During hip arthroscopy, you will receive anesthesia to keep you comfortable and pain-free. The surgeon will then make small incisions to insert an arthroscope and specialized tools, using fluid to expand the joint space, allowing them to visualize and repair damaged tissues.

You will typically receive general anesthesia, meaning you will be asleep during the entire procedure. Sometimes, regional anesthesia (spinal or epidural block) is used, which numbs your lower body, and you may also receive sedation to help you relax. Your leg will be gently pulled (traction) to create space in the hip joint, allowing the surgeon to see and work more easily. Once the joint is expanded, the surgeon makes small incisions, usually two to four, called portals. Through these portals, the arthroscope and tiny instruments are inserted. A sterile fluid is continuously pumped into the joint to keep it clear and expanded. The surgeon uses the instruments to trim, smooth, or repair damaged cartilage, remove loose bodies, or address other specific problems identified during the procedure. After the necessary repairs are made, the instruments are removed, and the small incisions are closed with stitches or sterile strips, then covered with a bandage.

Recovery & timeline

Recovery from hip arthroscopy typically involves managing pain, using crutches for several weeks, and diligently participating in physical therapy to restore strength and range of motion. While immediate recovery takes weeks, full recovery and return to normal activities can often take several months.

Immediately after surgery, you will likely experience some pain and swelling, which can be managed with pain medication and ice packs. You will usually need to use crutches for a period, often between two to six weeks, to limit weight-bearing on your hip and protect the healing tissues. Your surgeon will provide specific instructions on how much weight you can put on your leg. Physical therapy is a crucial part of recovery. A physical therapist will guide you through exercises designed to improve your hip's flexibility, strength, and range of motion. Adhering to your physical therapy program is vital for a successful outcome. Most people can return to light daily activities within a few weeks, but returning to sports or more strenuous activities may take three to six months or even longer, depending on the extent of the surgery and your individual progress.

Risks & side effects

While generally considered safe, hip arthroscopy, like any surgery, carries potential risks and side effects. These can include infection, nerve damage, blood clots, or continued hip pain, though serious complications are uncommon.

Common, less serious side effects include temporary numbness or tingling in the groin or foot, swelling, and discomfort around the incision sites. These usually resolve on their own. More serious, but less common, risks include infection in the joint, which may require further treatment, and deep vein thrombosis (DVT), a blood clot in the leg, which can be prevented with medication and early movement. There is also a small risk of damage to nearby nerves or blood vessels during the procedure. For example, the pudendal nerve, which supplies sensation to the genital area, can sometimes be affected by the traction used during surgery, leading to temporary numbness. In rare cases, the traction itself can cause skin irritation or nerve injury. Some people may also experience ongoing hip pain or stiffness, or the need for additional surgery in the future.

Success rate

Many people experience significant pain relief and improved hip function after hip arthroscopy, particularly for conditions like femoroacetabular impingement (FAI) and labral tears. While outcomes are generally positive, success rates can vary based on the specific condition treated, its severity, and individual factors.

For conditions such as FAI and labral tears, hip arthroscopy often leads to good or excellent results in a majority of patients, with many reporting reduced pain and better mobility. Studies suggest that a high percentage of patients, often around 70% to 90%, experience improvement in their symptoms and can return to their desired activities, including sports, after a full recovery. However, the success of the procedure can depend on several factors, including your age, the extent of cartilage damage, and how closely you follow your post-operative rehabilitation program. While many find lasting relief, some individuals may not achieve complete pain resolution or may require further treatment in the future. It's important to discuss realistic expectations and potential outcomes with your surgeon based on your specific condition.

Frequently asked questions

How soon after hip arthroscopy can I start physical therapy?

Physical therapy usually begins very soon after surgery, often within a few days. Early mobilization and guided exercises are crucial for regaining strength, flexibility, and proper function of your hip joint. Your surgeon and physical therapist will outline your specific rehabilitation plan.
