A Joint-Preserving Option For Hip Dysplasia
Periacetabular osteotomy (PAO) is a surgical procedure used to treat hip dysplasia, a condition in which the acetabulum, the cup-shaped portion of the pelvis that forms the hip socket, is misaligned or deformed.
When the hip socket is too shallow or improperly aligned, it may not provide adequate support and coverage for the femoral head. Over time, this can cause pain, restricted mobility, and excessive wear on the cartilage and labrum.
PAO is designed to correct this underlying structural problem by repositioning the acetabulum within the pelvis.
Benefits Of Periacetabular Osteotomy
Every PAO evaluation begins with understanding your symptoms, hip anatomy, activity level, and overall joint health to determine whether joint-preserving surgery may be appropriate.
Treats Hip Dysplasia
Designed to address misalignment or deformity of the acetabulum.
Improves Hip Coverage
Repositions the acetabulum to provide better coverage of the femoral head.
Preserves the Natural Hip
A joint-preserving approach designed to improve hip function while delaying the need for hip replacement.
Why PAO Is Used
For Hip Dysplasia
In patients with hip dysplasia, the acetabulum may be too shallow or improperly aligned, failing to provide adequate support and coverage for the femoral head, or the “ball” of the hip joint.
This misalignment can cause excessive wear on the cartilage and labrum, potentially leading to pain, restricted movement, and degeneration of the hip socket.
PAO addresses the underlying structure of the joint by repositioning the acetabulum within the pelvis, with the goal of restoring more normal hip joint anatomy.
Who May Be A
Candidate For PAO?
PAO is typically recommended for younger patients, generally under 40 years old, who have hip dysplasia but have not yet developed advanced damage to the joint surface cartilage.
For older patients, generally age 50 and above, with advanced osteoarthritis, total hip replacement may be a better option for alleviating pain and restoring mobility.
Determining the appropriate treatment requires careful evaluation of the hip and the individual factors that may affect treatment.
What Happens During
Periacetabular Osteotomy?
PAO is a complex procedure that requires careful preoperative planning to reposition the hip socket while protecting the surrounding structures.
Preoperative Planning
Planning includes a thorough physical examination, patient history, and imaging studies such as X-rays, MRI, and possibly three-dimensional CT scans.
Repositioning the Hip Socket
A series of cuts are made to the bone so the acetabulum can be repositioned within the pelvis to restore more normal hip joint anatomy.
Stabilizing the Acetabulum
Once repositioned, the acetabulum is stabilized with screws while new bone forms across the cut surfaces and secures it in its new position.
Protecting Surrounding Structures
The surgery is performed under X-ray guidance to help protect the surrounding nerves and muscles.
Recovery After Periacetabular Osteotomy
Recovery after PAO takes place gradually as the repositioned acetabulum heals in its new position.
2–4 Days — Hospital Recovery
Patients are usually hospitalized for approximately two to four days after surgery.
6–8 Weeks — Crutches + Protected Weight Bearing
Physical therapy and weight-bearing guidelines begin before discharge, with crutches typically used for six to eight weeks.
Around 3 Months — Return to School or Work
Most individuals can return to school or work after approximately three months.
6–12 Months — Return to Athletic Activity
If both hips are affected, surgeries are performed four to six months apart. Return to athletic activities may occur between six and twelve months.

Hip Dysplasia
Hip dysplasia, or developmental dysplasia of the hip (DDH), is a condition where the hip joint doesn't form properly, ranging from shallow sockets to complete dislocation. Symptoms include groin or hip pain, and diagnosis involves medical history and X-rays. Treatments range from non-surgical options like harnesses to surgery, emphasizing early detection for better outcomes.
Hip Osteoarthritis
Manage Hip Osteoarthritis: Non-surgical treatments include weight management, therapy, medications, injections, devices, and heat therapy. Surgical options like arthroscopic debridement or total hip replacement may be needed if non-surgical methods fail. Post-surgery, rehabilitation with therapy and assistive devices aids recovery. Improve quality of life despite this chronic condition.
Hamstring Tendon Tears
Understanding Hamstring Tendon Tears: Grades, Symptoms, and Treatment: Hamstring tendon tears range from mild strains to complete muscle tears, often affecting athletes. Classified into grades based on severity, treatment involves RICE therapy initially followed by gradual exercises. Symptoms include pain, stiffness, and swelling, with prevention strategies emphasizing stretching and warming up. Seeking medical advice is crucial for proper diagnosis and management, particularly for severe or recurring injuries. Learn more about managing hamstring injuries here.
