Exactech, Inc., based in Gainesville, Florida, recently held the full market launch of the Optetrak Logic CC revision knee system; Alteon monobloc revision femoral stem; Equinoxe humeral reconstruction prosthesis; and the InterSpace tapered wedge hip spacer at the annual meeting of the American Academy of Orthopedic Surgeons (AAOS).
Exactech: Full Launch of Revision Systems and Expansion of Technologies

According to the March 14, 2017 news release, highlights of Exactech’s latest innovations include:
- The Equinoxe Humeral Reconstruction Prosthesis offers a unique and stable solution for complex and challenging shoulder arthroplasty cases with significant humeral bone loss. Also featured was the new Preserve Stem, a conservative treatment option designed for preserving humeral bone.
- The Optetrak Logic CC Revision Knee System offers a comprehensive portfolio to help surgeons address challenging revision cases. Exactech’s redesigned, intuitive instrumentation for an efficient, streamlined surgical experience will also be showcased.
- The Alteon Monobloc Revision Femoral Stem is a press-fit, distally fixed, one-piece tapered, splined titanium stem. It incorporates specific philosophies designed to improve surgical experiences and clinical outcomes for hip arthroplasty patients.
- The InterSpace Tapered Wedge Hip Spacer and data behind InterSpace’s preformed spacer technology with 20 years of clinical experience will be showcased. The AcuDriver Automated Osteotome Handpiece for implant removal was featured in live demonstrations.
Exactech CEO David Petty told OTW, “Exactech is pleased to now be in full launch mode with our latest innovations that address complex and challenging cases for surgeons and improved outcomes for patients. Our AAOS line-up included the full launch of three revision systems and expanded advanced surgical technologies.”
“For instance, the Equinoxe Humeral Reconstruction Prosthesis is the latest addition to our fast-growing Equinoxe shoulder system. The platform modular stem for hemiarthroplasty, anatomic total shoulder and reverse total shoulder applications allows us to support patients who have few options for reconstruction due to significant humeral bone loss. It integrates with the entire Equinoxe shoulder system, giving the surgeon intra-operative flexibility. (The Equinoxe Humeral Reconstruction Prosthesis is not indicated for use with the reverse shoulder components in oncology applications.)”
“The Optetrak Logic CC Revision Knee System includes a high-performance portfolio of implants, instruments and computer-assisted surgery for reproducible results in revision procedures. Intuitive instrumentation provides modularity and supports a streamlined technique to more quickly and efficiently prepare bone resections. ExactechGPS supports these cases with real-time data and the personalized workflows surgeons need to address the most challenging revision cases.”
“The Alteon Monobloc Revision Femoral Stem is a press-fit, distally fixed, one-piece tapered, splined titanium stem. It is designed to achieve axial and rotational mechanical stability and operative predictability.”
“We’re proud to continue to expand our InterSpace line with the addition of a tapered wedge hip spacer. Designed to temporarily replace an infected implant, InterSpace is the first pre-formed spacer with 96.1% eradication rate.”

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
