Secure Tracks Device Improves Functional Recovery and Pain after Total Knee Arthroplasty: A Prospective, Randomized, Pilot Study

• Unilateral TKA• Control: 15 patients with walker• Study: 15 patients with Secure Tracks

Results…

• Ambulated ~2x further• Decreased pain• Significantly better TUG scores• THA showed similar findings

What does this mean???

• Better circulation• Lower risk of DVT• Maintain strength• Load implants• Bone remodeling process• Shorter hospital stay???• Fewer complications???

Compared to LiteGait

• Only runs on track• Not designed for unweighting• Less space required• No harness• Efficient
