Restoring Mobility for Those in Need Through Free Joint Replacement Surgeries

Operation Walk Los Angeles is a volunteer medical humanitarian organization that provides the gift of mobility through life-changing joint replacement surgeries at no cost for those in need in the U.S. and globally.

During each international surgical mission, Operation Walk educates in-country orthopedic surgeons, nurses, physical therapists and other healthcare professionals on the most advanced treatments and surgical techniques for diseases of the hip and knee joints.

Watch Our Mission in Action

Every Step Forward Starts with a Single Surgery

A joint replacement surgery lasts a few hours. Its impact lasts a lifetime. For patients who can’t work, can’t walk, and have lived with chronic pain for years, these surgeries restore far more than movement — they restore independence, dignity, and hope.

Operation Walk brings together world-class surgeons, dedicated volunteers, generous donors, and compassionate supporters to deliver life-changing orthopedic care to those who need it most, at no cost to them.

From mission planning to recovery, every step of the journey is made possible by people who believe access to care should never depend on where you were born.
