As Texans offensive tackle Derek Newton recuperates from a successful surgery to repair a torn of patellar tendons, doctors gave their input to The Chronicle on his medical situation and outlook.
The following answers were provided by Brian Schulz, MD, orthopedic surgeon at Kerlan-Jobe Orthopaedic Clinic in Los Angeles:
What is the nature of torn patellar tendons?
