In the wake of Jeremy Lin rupturing his right patellar tendon during Wednesday’s season opener, a specialist told The Post it’s reasonable to think the Nets point guard could be back on the court next season, but there’s no guarantee the 29-year-old will ever regain his full form. “A number of things have to happen,” said Dr. James Gladstone, orthopedic surgeon and co-chief of sports medicine at the Icahn School of Medicine at Mount Sinai. “One, it has to be healed back into place. Second, you have to have the right tension in that tendon. If it heals and it’s stretched out, it doesn’t matter how strong your quadriceps are, you can’t generate the same force through the knee. “For someone who has to twist, sprint, jump and pivot, the rehab’s going to be longer and more involved. The problem is even though the injury is the same … how it happens to each person, how it heals, how as an individual they respond to injury can be very different. Somebody like Jeremy Lin could make a 100 percent recovery, or he could end up like Victor Cruz, only playing at 80 percent of past potential. You can’t predict that type of thing, that individual biology.”
