Hip arthroscopy before prosthesis: when it is necessary and how to decide on the best treatment
When hip pain does not improve with conservative treatment, two surgical alternatives usually appear that generate many doubts: hip arthroscopy before prosthesis and total hip replacement. The choice between one and the other does not depend on taste, but on clear clinical criteria. Here we explain in which situations each procedure is usually the most appropriate.
What is hip arthroscopy and in which cases is it performed?
Description of the procedure and surgical technique
Arthroscopic hip surgery is a minimally invasive procedure. The surgeon inserts a small camera and specialized tools through incisions of a few millimeters. To enter the joint space safely, controlled traction is applied to the leg. In this way, you can see and treat what is happening inside the joint without having to “open” the hip completely.
Traction is a critical technical step: it temporarily separates the femur from the acetabulum and creates the space needed to work precisely within the joint.
Labral injuries and femoroacetabular impingement
The most common indications for this surgery include a ruptured labrum and femoroacetabular impingement, also called femoral-acetabular impingement. In these cases, an abnormal shape of the bone produces repeated friction and ends up damaging the cartilage and soft tissues around the joint. According to the American Academy of Orthopaedic Surgeons, arthroscopic labral repair can relieve pain and help regain function when hip osteoarthritis is mild or moderate.
When is hip arthroscopy recommended before considering a prosthesis?
Mild, moderate and advanced osteoarthritis: what changes in the indication
The degree of hip osteoarthritis is what weighs most in the decision. When osteoarthritis is mild or moderate, the joint space remains relatively preserved and there is no major collapse of the cartilage. In this scenario, hip arthroscopy can treat the mechanical origin of the pain. In many patients, this makes it possible to avoid or at least delay a total hip prosthesis.
When osteoarthritis is advanced, the cartilage is already very deteriorated. In this context, operating with arthroscopy usually gives unpredictable results and, in many cases, the pain returns in a few months.
Red Flags for Considering a Hip Replacement
There are signs that tend to point more towards hip replacement than arthroscopy:
- Severe pain that does not get better with rest or medication
- Marked loss of joint space on X-rays or other images
- Difficulty walking short distances
- Sustained drop in quality of life despite conservative treatment
When is arthroscopy NOT appropriate and a total hip prosthesis is directly assessed?
There are situations where arthroscopy is not a good option. Advanced osteoarthritis, extensive avascular necrosis , irreducible dislocation, or a severe hip fracture are usually direct indications for hip replacement. In these cases, arthroscopy first only delays definitive treatment and may make subsequent surgery difficult. Avascular necrosis, for example, affects femoral bone irrigation progressively and irreversibly, and rarely improves with an arthroscopic approach.

How to decide between arthroscopy and hip replacement: clinical criteria and images
The decision is made by assessing several elements at the same time. The specialist reviews the patient’s age, activity level, the degree of osteoarthritis on X-rays and MRI, and the type of injury present. They also analyze whether there is dislocation, labral damage, impingement or involvement of the subchondral bone.
In general, a young, active patient with femoroacetabular impingement and relatively preserved cartilage is usually a good candidate for arthroscopy. In contrast, an older patient with advanced osteoarthritis and significant cartilage loss usually obtains a clearer benefit from hip arthroplasty.
Risks and complications: arthroscopy vs. hip prosthesis
Risks of arthroscopic hip surgery
The risks of arthroscopic hip surgery are low, but they exist. Prolonged traction can cause transient nerve damage. Infection, bruising, or stiffness may also occur during recovery. In a small percentage, symptoms do not improve as expected, and over time, a hip replacement is indicated.
Risks of Total Hip Replacement
Total hip prosthesis involves risks typical of major surgery: deep infection, venous thrombosis, dislocation of the prosthesis, long-term loosening of the implant and, to a lesser extent, periprosthetic hip fracture. Even with these risks, when the indication is correct, the results are usually very good. Studies published in the National Arthroplasty Registry report implant survival rates above 90% at 15 years.

Before the Procedure: Preparing for Hip Surgery
General anesthesia and spinal anesthesia: options available
Both arthroscopy and prosthesis require prior preparation. Blood tests, imaging studies and a cardiovascular assessment are requested. As for anesthesia, hip arthroscopy can be done with general anesthesia or spinal anesthesia, depending on the patient’s condition and the criteria of the medical team. Spinal anesthesia blocks the sensitivity of the lower body and can help reduce the need for analgesics in the postoperative period.
Recovery and rehabilitation: real times and expectations
Postoperative recovery after hip arthroscopy
After hip arthroscopy, most patients go home the same day or the next day. Postoperative pain is usually moderate and manageable. Full recovery takes between three and six months, depending on the injuries treated and the patient’s previous activity.
Physical therapy, crutches, and return to normal activity
The use of crutches during the first weeks is common, as it helps protect the joint while regaining strength and stability. Physiotherapy starts early and progresses step by step. Mobility and strengthening exercises allow you to gradually resume daily activities. In hip arthroplasty, rehabilitation is also key: patients start walking with assistance within the first 24 hours.
Minimally invasive surgery for hip replacement: modern alternative
Minimally invasive techniques and anterior surgery
Minimally invasive techniques have changed the way hip replacement is performed. The anterior route, in particular, respects the gluteal muscles and usually allows for faster recovery. This approach does not section important muscles, which reduces postoperative pain and shortens the time spent using crutches.
Hip prostheses without prolonged hospitalization
With these techniques, the hospital stay is usually much shorter. In some cases, discharge is given within 24 to 48 hours. This approach improves the patient experience and helps decrease the risk of complications related to long hospital stays.
Frequently asked questions about hip arthroscopy before prostheses
¿La artroscopia puede evitar definitivamente la prótesis de cadera?
In mild or moderate osteoarthritis with occasional injuries, you can avoid it or, at least, postpone it. When osteoarthritis is advanced, it usually only offers temporary relief.
¿Cuánto tiempo dura la recuperación tras una prótesis total de cadera?
Most patients return to basic activities in four to six weeks. Full functional recovery can take up to three months.
¿Es posible operar con artroscopia si ya hay artrosis avanzada?
It is not usually recommended. In that scenario, hip replacement offers more predictable and long-lasting results.
¿Qué diferencia hay entre reemplazo de cadera y artroplastia de cadera?
They are equivalent terms. The two describe the same procedure: replacing the damaged joint with an artificial implant.
