HSS Studies Challenge Conventional Wisdom on Osseointegration for Amputees

Event summary

  • HSS presented three studies at the 2026 AAOS Annual Meeting challenging assumptions about osseointegration (OI) for amputees.
  • OI procedures performed at HSS since 2017 exceed 300, making it the most experienced center in the U.S.
  • Studies found comparable benefits for both femur-level and tibia-level OI patients, contradicting prior beliefs.
  • Custom 3D-printed implants showed promising early results with no implant loosening or distal chip fractures.
  • Research suggests OI could be offered at the time of amputation, bypassing traditional socket prosthetics.

The big picture

These studies position HSS as a leader in challenging orthopedic conventions, potentially expanding the OI market beyond its current niche. The findings could accelerate adoption of this technology, particularly for below-knee amputees who were previously considered good candidates for traditional socket prosthetics. The use of custom 3D-printed implants represents an emerging trend in personalized medical device manufacturing.

What we're watching

Adoption Expansion
Whether tibia-level amputees will increasingly adopt OI as standard care following these findings.
Surgical Timing
The pace at which simultaneous amputation and OI procedures gain acceptance among surgeons.
Custom Implant Growth
