First... wait for it to heal. Then, it is my understanding that connective tissue (tendons and ligaments) are best strengthened with lightweight, high rep exercises. This is because they grow at a much slower rate than muscle, and the lighter weight will sort of compensate for that.
However, nothing will stress you body (and cause growth and strengthening) like heavy weights and low reps: you'll increase tendon strength, muscle strength, bone density, ligament strength. But heavy lifting has considerably more risks, ESPECIALLY if you're comming back from an injury. That being said, you can lift heavy for your whole life without incident if you lift properly.
Basically, let it heal properly, then rehab it, then do some high rep resistance work (15-20 reps) for a couple months (remember, burning in muscles = ok. sharp pain in joints and at insertion points = bad and stop what you're doing or lighten the weight until it doesn't happen) and then move on the bigger (and heavier) things.
