If one leg feels longer after hip replacement, it can be hard to tell whether your legs actually measure differently or your body is still adjusting to a new hip. Both can happen. The difference may be structural, or it may come from muscle contracture or the way your spine and pelvis affect your body mechanics.
At Robotic Hip and Knee Replacement LA, Dr. Farzin Kabaei provides hip replacement evaluations and second opinions for patients in Los Angeles and Santa Monica.
Why Can a Leg Feel Longer After Hip Replacement?
Mayo Clinic explains that arthritis can narrow the joint space and cause bone loss, shortening the affected leg before surgery. When hip replacement restores that lost height, the operated side may feel longer because your body had adapted to the shorter leg.
Other reasons can include:
- Contracture of muscles around the hip, which can affect leg length during recovery
- Scoliosis or other conditions that change body mechanics after replacement
- A small actual difference in leg length when exact equality isn’t possible while maintaining hip stability
Can Hip Replacement Actually Change Leg Length?
Yes. Surgeons aim to restore appropriate leg length, but Mayo Clinic notes that perfectly equal measurements aren’t always possible. In some cases, a slight difference may be necessary to keep the replaced hip stable.
If the uneven feeling persists or changes how you walk, an orthopedic evaluation can determine whether a measurable discrepancy exists.
How Is Leg Length Discrepancy After Hip Replacement Checked?
A systematic review indexed by PubMed found that clinicians use both clinical measurements and imaging to assess leg-length discrepancy after total hip replacement. Reliability varied among the methods studied, so the measurement needs to be interpreted as part of the broader orthopedic evaluation.
Dr. Kabaei can review your symptoms, prior surgical history, and imaging to evaluate what may be contributing to the difference you notice.
Where Does Robotic Planning Fit In?
For patients considering robotic hip replacement in Los Angeles, Dr. Kabaei uses the Mako robotic-assisted system as part of his anterior hip replacement practice. Robotic planning is one part of the surgical process. Mayo Clinic’s guidance is useful here, too: surgeons have to consider hip stability as well as leg length when reconstructing the joint.
FAQ
Can the feeling that one leg is longer improve after hip replacement?
Yes, it can. Mayo Clinic notes that small leg-length differences often become less noticeable after a few months. When muscle contracture contributes to the problem, strengthening and stretching those muscles over time may help.
Should I get another opinion if my legs still feel uneven?
If the difference continues to concern you or you want another surgeon to review your imaging and prior treatment, Dr. Kabaei offers hip replacement second opinions in Los Angeles.
