Biological healing is becoming increasingly important and popular. Biological healing entails using the patient’s own biology (such as growth factors in the blood, etc.) to aid healing and to help creature a more favourable environment to healing to take place. We also attempt to disturb the patient’s biology or tissue as little as possible, firstly to aid in the healing process and secondly to prevent and avoid further damage from the procedure. This is mainly evident in our ACL reconstruction technique.
