Devices and systems for use in soft tissue repair are provided, as are methods of manufacturing the same. In one exemplary embodiment, an implantable surgical construct includes an implant and a continuous braided closed filament loop that is attached to the implant. The continuous loop can be formed from a single strand of filament such that portions of the filament, sometimes referred to as tails, can be arranged with respect to each other to form a braided configuration. A related method of manufacture can involve passing portions of a single strand of filament around different sets of posts and selectively over and under each other to create the braided configuration. Other devices, systems, and methods of manufacturing are also provided, including some that involve using multiple strands of suture to form a continuous braided closed filament loop.
