Design of Human Skeletal Muscles: Implications for Orthopaedic Surgery

Richard L. Lieber, PhD, of the University of California, San Diego, received the 2013 Kappa Delta Elizabeth Winston Lanier Award for his research outlining the complex and varying characteristics of skeletal muscles, and the implications of these differences in orthopaedic surgery and patient outcomes.

"Skeletal muscles demonstrate a sophisticated design at a variety of levels," said Lieber. For example, the wrist is "composed of muscles with varying fiber length and fiber which makes some of them very strong, while others can move greater distances."

Lieber and his team developed a portable tool that passes laser light through muscles during surgery, recording a pattern that precisely measures the sarcomere, the microscopic machinery of the muscle. In addition, the researchers documented the unprecedented changes that occur in muscle contractures.

"This tool and concept allows surgeons to move muscles, and to objectively set them to the length at which they will develop the maximum force instead of simply relying on the feel of muscle in the operating room," said Lieber.

When doing a tendon transplant or transfer, "this information can be used to determine the best donors to restore lost function due to injury."

Improving Outcomes for Posterolateral Knee Injuries

Robert LaPrade, MD, PhD, a complex knee surgeon at the Steadman Clinic in Vail, Colo., was awarded the 2013 Orthopaedic Research and Education Foundation (OREF) Clinical Research Award for his work on improving diagnosis and treatment for complex injuries to the posterolateral (back corner) of the knee.

Based on an extensive number of peer reviewed publications on this topic, Dr. LaPrade and his research team developed a set of guidelines and anatomic-based surgical reconstructions that clinicians can use to diagno
