About the Lab

Professor Hyun Jang Jeong's research lab specializes in orthopedic surgery and musculoskeletal health, with a primary focus on rotator cuff repair and postoperative complications such as postoperative neck pain (PONP). The lab investigates biomechanical optimization of surgical techniques—such as the optimal insertion angle for suture anchors—and evaluates long-term outcomes and patient-specific risk factors. Their work also extends to improving caregiver support in dementia care, emphasizing tailored psychosocial interventions to reduce burden. The lab integrates clinical research with biomechanical analysis to enhance surgical outcomes and patient-centered care.

SJR Q2FWCI 2.5Clinics in Shoulder and ElbowOA

The ToR technique produced comparable clinical outcomes to conventional techniques. Considering the prospect of potential additional surgeries, the absence of peri-implant cyst formation might be an advantage of ToR. Furthermore, ToR might reduce the medical costs related to suture anchors and, thereby, could be a useful option for ARCR. Level of evidence: III.

Postoperative New-Onset Pseudoparalysis: A Retrospective Analysis of 430 Consecutive Arthroscopic Repairs for Large to Massive Rotator Cuff Tears
Hyeon Jang Jeong, Sung-Min Rhee, Joo Han Oh
SJR Q1FWCI 0.7The American Journal of Sports Medicine

Although the incidence of PONP after ARCR was low (6.0%), the risk of PONP was higher in patients with a torn subscapularis, larger supraspinatus tear size, older age, and preoperative stiffness. The mean time from PONP onset to reversal was 10 months, and PONP reversal was affected solely by fatty infiltration of the supraspinatus. Therefore, surgeons should consider the risk for PONP and attempt to identify high-risk patients before rotator cuff repair.

Trabecular Bone Score Could Not Predict the Bone Mineral Density of Proximal Humerus

TBS and conventional hip and LS DXA did not represent proximal humeral BMD. Furthermore, among the various radiological measurements, the BMD of the GT was a sole risk factor of ISAF. Therefore, further research for the direct measurement of proximal humeral BMD is mandatory to predict proximal humeral focal osteoporosis.
