This practice is built around precision. That means planning, soft-tissue respect, advanced technology, fixation strategy, and recovery execution.
Designed to provide long-lasting pain relief and restore daily function when arthritis or joint degeneration is the primary cause of hip pain.
A muscle-sparing surgical approach that may allow faster recovery and improved early mobility for appropriately selected patients.
Advanced technology that supports precise planning and accurate implant placement to enhance outcomes in selected cases.
A specialized procedure to address previously replaced hips that are experiencing instability, stiffness, loosening, or infection.
For arthritis when nonoperative care no longer preserves function.
When disease is truly compartmental and mechanics support it.
Utilizes advanced technology to assist surgeons in creating a highly personalized surgical plan and executing it with extreme precision.
A specialized procedure to address previously replaced knees that are experiencing instability, stiffness, loosening, or infection.
Specialized treatment for fractures occurring around existing hip or knee implants, requiring urgent intervention and expert stabilization.
A comprehensive approach to evaluating and treating infections in joint replacements using evidence-based clinical pathways.
If you’re early in the arthritis curve, or you’re trying to buy time, there are high-yield nonoperative strategies that can meaningfully improve function.

Built around your goals, your anatomy, and what will hold up long-term, with the right option chosen at the right time.
We align goals, then choose the right tool (nonop vs op).
Prehab + multimodal pain control strategies designed to minimize opioids when possible.
Implant and fixation choices matched to bone quality and activity goals—planning for years, not weeks.

Dr. Leo Zalikha is a Stanford-trained orthopaedic surgeon specializing in adult reconstruction, with a focus on hip and knee arthritis care, primary and complex joint replacement, and revision surgery. He combines meticulous surgical technique with modern planning and technology, and offers the full spectrum of care including PRP and biologics when appropriate. Dr. Zalikha served as a Clinical Instructor at Stanford Medicine during fellowship and remains active in research, with over 30 peer-reviewed publications and book chapters and a particular interest in how emerging technologies can elevate patient outcomes.
Dr. Zalikha’s patients are encouraged to share their experiences. Reviews can be found on Google and other review platforms. His goal is for every patient to feel heard, well-informed, and confident in their care from the first visit through full recovery.
“Dr. Zalikha was excellent at explaining my condition, the options, risks and benefits of a hip replacement. I trust what he says based on his professionalism and demeanor.”
“Dr. Z made me feel very comfortable moving forward with this invasive procedure (hip replacement), mostly due to his knowledge, experience and willingness to patiently answer my questions in ways that I could understand.”
“My experience with Dr. Zalikha was excellent. I was very happy how he took the time to go over my concerns. He did diagnose a partially ruptured hamstring and ordered PT. Already feeling better. Thank you Dr Zalikha.”
Clear, practical, surgeon-written.
One of the most successful and reliable procedures in modern medicine. For patients with advanced hip arthritis or other conditions that have not responded to conservative treatment, hip replacement can dramatically reduce pain, restore mobility, and allow a return to the activities that matter most.
Read the guideIt relieves pain and restores function for people whose knees have been damaged by arthritis, injury, or wear. Over 700,000 knee replacements are performed in the United States each year, making it one of the most common and successful elective surgeries. The majority of patients report significant pain relief and improved ability to walk, climb stairs, and return to the activities they enjoy.

These fractures can happen after a fall, a twisting injury, or sometimes with minimal trauma in patients with weakened bone (osteoporosis). They are among the most challenging problems in joint replacement surgery.

Schedule a ConsultationThis will be diagnosed based on your exam, clinical history, imaging, and other tests. Treatment is based on the severity of your symptoms, the impact on your quality of life, and how well nonoperative treatments are working. If arthritis pain consistently limits your daily activities despite reasonable conservative management, joint replacement may be appropriate. Dr. Zalikha will review your imaging, examine your hip or knee, and help you determine the right timing.
Most patients start with a structured nonsurgical plan: physical therapy, weight optimization and lifestyle changes, and targeted injections for joint pain such as corticosteroid, hyaluronic acid, or PRP. With the right combination, many people experience meaningful relief for months or even years — and even if surgery becomes necessary later, starting with conservative care leads to better outcomes.
When nonsurgical treatment no longer provides relief and pain begins to affect daily life, it may be time to explore surgical options. If arthritis pain consistently limits your daily activities despite reasonable conservative management, joint replacement may be appropriate. Dr. Zalikha ensures that decision is made carefully and collaboratively, only when truly needed.
It is not “robot surgery” — the surgeon performs every aspect of the procedure. Before surgery, a CT scan creates a 3D model of your anatomy that Dr. Zalikha uses to plan implant size, position, and alignment. During the operation, the robotic system provides real-time guidance to help execute that plan with a high degree of accuracy, while the surgeon remains in full control at all times.
No. While the anterior approach is appropriate for the majority of primary hip replacements, factors such as body habitus, prior hip surgery, or complex deformities may make a different approach a better choice. Dr. Zalikha is trained in multiple approaches and will assess your anatomy, imaging, health status, and goals to give you an honest recommendation.
New or persistent pain in a replaced joint should not be ignored. It can have several causes, and a thorough workup is essential — including ruling out infection. If you experience new or worsening pain, swelling, warmth, drainage, or fever, seek prompt evaluation; early evaluation and intervention improve the chances of successful treatment.
The workup typically includes blood tests for markers of inflammation, joint aspiration with cell counts and cultures to identify the specific bacteria, and X-rays or advanced imaging when needed. In some cases the definitive diagnosis is made during surgery, when tissue samples are sent for culture and pathology. Dr. Zalikha manages prosthetic joint infection in close collaboration with infectious disease specialists.
Bring your photo ID and insurance card, a list of current medications (names and dosages), any relevant imaging such as X-rays, MRIs, or CT scans, a list of prior surgeries — especially previous hip or knee procedures — and notes about your symptoms and the treatments you have already tried. If you have had joint surgery elsewhere, operative reports and implant records are helpful.
