Achilles tendon ruptures can be treated both operatively and non-operatively. With either technique, patients can be either be immobilized initially, or allowed some weight-bearing and range of motion, otherwise known as "Early" or "Functional" rehabilitation. While early mobilization may have benefits in terms of return to activity and function, it is unclear whether it is also associated with adverse events. In this study, the authors assessed 14 randomized controlled trials which compared these protocols. Overall, on a wide range of outcomes including adverse events, function, and return to work and sport, the only significant difference was a slightly faster return to work time with the early mobilization group.
