I did the exact same thing. drilled two holes through the elbox and pulled the tendon through and secured. Took about 3 months to be able to lift with any confidence, 4 months to push moderate weights, 6 months to push it hard. i have some mild atrophy in that tricep, and a little more difficulty contracting it, but I still pound it like I did before I hurt it. but you have to work back up and be smart. reverse grip pushdowns with light weights was the best rehab for it, and also the most painful. I lost about 2 inches on my arm after the surgery, but they came back within 8-9 months...
