torn ACL & lateral meniscus

I tore my ACL & lateral meniscus in feb. In March I had reconstructive surgery, using a cadaver. It has now been 3 months since my surgery and my range of motion is only at 108 degrees. My doctor and physical therapist said that my knee heeled too fast and has a lot of scar tissue. I didn’t get one of those flexion machins after my surgery. I was wondering if I will be able to play basketball this upcoming season. Will I need to wear a brace? How can I speed up my recovery? Will I gain my range of motion?
