New York City-based Hospital for Special Surgery presented three 2024-2025 studies on osseointegration outcomes in patients with limb amputations at the American Academy of Orthopaedic Surgeons 2026 Annual Meeting in New Orleans.
The first study compared 83 femur-level and 64 tibia-level patients who underwent press-fit osseointegration. Both groups saw significant gains in mobility and satisfaction, with no difference in adverse events, challenging the view that only femur osseointegration patients benefit, according to a March 5 news release.
The second study reviewed 139 procedures, comparing patients who had osseointegration performed at the same time they underwent amputation to those treated with an existing amputation. Both groups showed similar improvements, supporting the option of simultaneous amputation for “select, well-informed patients who prefer to bypass the trial of a socket prosthesis,” the release said.
A third study examined 19 patients who received custom 3D-printed implants. All had significant outcome gains, with no loosening or intraoperative fractures reported.
The results support broader use of osseointegration, including for below-the-knee and newly amputated patients, according to the release.
At the Becker’s 32nd Annual Meeting: The Business and Operations of ASCs, taking place October 29-31 in Chicago, ASC leaders, surgeons and healthcare executives will explore strategies to drive growth, enhance operational performance, navigate reimbursement challenges and prepare for the future of ambulatory surgery.
