Stryker acquired Stanmore Implants Worldwide in an all-cash transaction for £35.6MM (~US $52MM). Stanmore Implants' portfolio comprises patient-specific and off-the-shelf implant systems for limb salvage.
Stanmore Implants was formed in 1996, with a foundation in the Institute for Orthopaedics at the Royal National Hospital in Stanmore, London. In 2007, the company began collaboration with Acrobot to develop computer assisted surgical techniques for implantation of Stanmore's patient-matched joint implants, and in 2010, the companies merged.
Stanmore received FDA 510(k) clearance to market its Sculptor Robotic Guidance Arm™ for precision implant placement in unicompartmental knee surgery in 1Q13, though it was challenged in the same quarter for patent infringement by MAKO Surgical. Soon after, MAKO agreed to settle the actions and acquire the assets of Stanmore's Sculptor Robotic Guidance Arm.
Stryker proceeded to acquire MAKO in 4Q13.
This marks the third orthopaedics-related acquisition for Stryker within 2016 (following Safewire and CareFusion VCF assets). Outside of orthopaedics, within the year Stryker has also acquired Physio-Control, Synergetics USA's neuro products and Sage Products.
