212-305-5561
Director;
Center for Orthopedic Research Biomechanics Laboratory.
Ongoing studies are devoted to sports medicine injuries,
elbow disorders, and shoulder disorders. Current clinical
studies are evaluating ACL injury prevention strategies,
outcome of “Tommy John” elbow ligament reconstruction,
shoulder throwing injuries, new arthroscopic rotator cuff
repair techniques, and reverse shoulder arthroplasty.
Supporting the clinical studies are basic science studies
in ACL reconstruction techniques, elbow ligament reconstruction
fixation strength, and evaluation of shoulder arthroplasty
stability. All students are welcome to join our research
team. |

Louis U. Bigliani, M.D., PH11-1130, 212-305-0998
Clinical studies in shoulder surgery including rotator
cuff, instability and total joint replacements, fractures,
arthroscopy and sports medicine are being pursued. Basic
science laboratory investigations are ongoing concerning
the morphology and structural properties of the inferior
glenohumeral ligament, labrum, their roles in anterior
inferior shoulder instability and development of osteoarthritis
in this joint. The anatomy pathology and contact patterns
of the subacromial space and rotator cuff are being studied. |

William B. Macaulay, M.D., PH 11-1146, 212-305-6959
Director, Center for Hip & Knee Replacement. Clinical
multicenter outcome studies in primary and revision hip/knee
surgery, post operative transfusion and hip fracture treatment.
Additional outcome studies include long term survivorship
analyses of primary and revision hip/knee prostheses as
well as exploration into improved methods of post operative
pain control and enhanced patient satisfaction following
total knee replacement. Basic science research interests
include the rational design of orthopedic implantsand
less invasive techniques, computer assisted surgery, the
biology of periprosthetic bone resorption, thrombogenesis
after total joint replacement, etiology and treatment
of osteonecrosis. |
