The issue with returning to match fitness is that usually individuals believe that the lack of pain is associated with full function. This is wrong, as pain is not necessarily an indicator of optimum function,

If this injury has recently recurred, you may want to consider ultrasound to enhance fibre alignment and healing,

Additionally, you want a progressive physiotherapy programme that assesses dynamic functional activities before you get back to match fitness. Without that you will likely re injure, and what will happen is chronic tissue changes that lead to long term delay of recovery.
