Prosthetic sockets for BKA are the critical interface between the residual limb and the prosthetic leg. A well-fitted socket distributes weight evenly, reduces pressure points, and ensures comfort and stability. Socket design can vary based on residual limb shape, activity level, and material preferences.Regular evaluation and adjustment of the socket are essential to prevent skin irritation, sores, or alignment issues. Properly designed and maintained sockets allow below-the-knee amputees to walk, stand, and perform activities with confidence while maintaining limb health.
