EXECUTIVE SUMMARY

• JAAOS Multicenter Study Demonstrates Significant Reduction in Acromial Fractures with 3D Preoperative Planning: A large 17-year retrospective cohort study of 2,380 patients published in JAAOS demonstrates that routine 3D virtual surgical planning and modern lateralized reverse total shoulder arthroplasty (rTSA) implant designs significantly decrease periprosthetic acromion and scapular spine fracture rates.
• Zimmer Biomet Expands Z1™ Triple-Taper Hip Stem Adoption with AI Navigation Integration: Zimmer Biomet announced that its Z1™ Triple-Taper Hip Stem now accounts for over 40% of its US femoral stem volume, driven by accelerating clinical adoption of integrated AI navigation workflows in outpatient total hip arthroplasty.
• Teleflex Medical OEM Launches as Independent Pure-Play MedTech INGENYX: Following completion of a $1.5 billion carve-out by Montagu and Kohlberg, INGENYX launched as a standalone developer and manufacturer of custom orthopaedic sutures, high-performance fibers, bioabsorbables, and surgical components.

JAAOS / Phillips et al. — 3D Preoperative Planning and Lateralized Designs Reduce Scapular Fractures in rTSA

A 17-year clinical study published in the Journal of the American Academy of Orthopaedic Surgeons (JAAOS) evaluated 2,380 patients undergoing reverse total shoulder arthroplasty (rTSA) to determine the impact of technological advancements on periprosthetic acromion and scapular spine fractures (ASF). The findings confirmed a significant reduction in fracture incidence over time, directly correlating routine 3D CT-based virtual preoperative planning and lateralized glenosphere/humeral designs with minimized scapular stress concentration and reduced complication rates in rotator cuff deficiency.

• Device/System Name: 3D Preoperative Virtual Surgical Planning & Lateralized rTSA Systems
• Status: Peer-Reviewed Clinical Trial Publication (JAAOS)
• Clinical Significance: Validates routine 3D surgical planning in mitigating acromial stress shielding and scapular fractures, improving long-term implant survival in complex reverse shoulder arthroplasty.

Zimmer Biomet — Z1™ Triple-Taper Hip Stem Reaches 40% US Adoption Supported by AI Navigation

Zimmer Biomet reported that its Z1™ Triple-Taper Hip Stem has achieved over 40% penetration across its US femoral hip portfolio. Anchored in the company's "triple play" hip strategy, the Z1 stem features a reduced-length, bone-conserving geometry designed for direct anterior and minimally invasive approaches. Accelerated uptake is supported by the platform's seamless pairing with AI-guided surgical navigation and digital planning tools in ambulatory surgery centers (ASCs).

• Device/System Name: Z1™ Triple-Taper Hip Stem & AI Navigation Platform
• Status: Commercial Operations / Q2 Operational Milestone
• Clinical Significance: Optimizes proximal femoral load transfer, reduces thigh pain and stress shielding, and streamlines component positioning in outpatient anterior hip replacement.

Sports Medicine & Soft Tissue Repair

BMJ Open / GRASE ACL Study Group — Multi-Center RCT Protocol for Primary ACL Graft Selection

The GRASE ACL study group published its multi-center randomized controlled trial protocol in BMJ Open evaluating optimal autograft selection for primary anterior cruciate ligament (ACL) reconstruction. The trial compares bone-patellar tendon-bone (BTB), quadrupled hamstring tendon, and quadriceps tendon autografts across standardized biomechanical and functional endpoints. The primary objective is to provide high-level evidence regarding graft-specific knee stability, donor-site morbidity, and return-to-sport rates.

• Device/System Name: GRASE ACL Clinical Protocol (BTB vs. Hamstring vs. Quadriceps Autograft)
• Status: Randomized Controlled Trial Protocol Published
• Clinical Significance: Clarifies surgical decision-making for graft selection, balancing donor-site morbidity against mechanical laxity to optimize athletic return-to-play timelines.
