RESEARCH

Dr. Chen performs clinical research on the newest techniques in arthroscopic surgery. He currently has several ongoing projects on the following topics. If you are an interested patient please contact our office for more information:


SUPERIOR CAPSULAR RECONSTRUCTION (SCR)

Superior Capsular Reconstruction is an arthroscopic surgical procedure that addresses massive irreparable rotator cuff tears by reducing superior humeral translation to improve shoulder kinematics by anatomically replacing the superior capsule of the shoulder with a dermal allograft. SCR was pioneered by Dr. Teruhisa Mihata in 2007 in Japan. Previously patients with irreparable rotator cuff tears were recommended to have reverse total shoulder replacement. However, the SCR is an arthroscopic procedure ideal for patients with irreparable rotator cuff tears.

MENISCUS TRANSPLANTATION

Meniscus transplantation is an arthroscopic surgical procedure that addresses a meniscus deficient knee. It is indicated in symptomatic patients with Grade 1 or 2 osteoarthritis. Many patients commonly have prior large or subtotal meniscectomy such as a removed bucket handle meniscus tear. However, symptomatic patients typically already have progressed to Grade 3 or 4 osteoarthritis of the knee by the time they have symptoms. Outcomes of meniscus transplantation in patients with Grade 3 and 4 osteoarthritis are significantly worse than patients with more preserved knees. Therefore meniscus transplantation may be advantageous in a meniscus-deficient knee before osteoarthritis has progressed.

ANTERIOR CRUCIATE LIGAMENT REPAIR (ACL Repair)

Anterior Cruciate Ligament Repair is an arthroscopic surgical procedure that repairs the native ACL by sewing the ligament together and placing a tensioned bridge or scaffold onto which the ACL can heal. Current state of the art for an ACL tear is reconstruction of the ligament by replacing the ACL with a cadaveric tendon or autograft tendon. Certain types of tears in young patients may be amenable to ACL repair thus shortening the rehabilitation process considerably without the need for placing a graft.
