Arthrex Inc. on Wednesday said it has opened its warehouse and distribution center on Plantation Road in Lee County. The Naples-based medical device manufacturer has relocated about 60 employees to what it calls the Arthrex Logistics Center at 14550 Plantation Road. The 240,000-square-foot building had previously served as a warehouse and distribution center for Robb & Stucky. Arthrex bought it for $12.5 million late last year. “We started moving into that facility last month,” spokeswoman Lisa Gardiner said. “It’s an ongoing process.”
