研究室紹介
Professor Seung Jae Lim's research lab specializes in hip joint surgery and orthopedic biomechanics, with a primary focus on degenerative and rare joint disorders such as primary synovial osteochondromatosis of the hip. The lab investigates surgical techniques—including open synovectomy, hip dislocation, and implantation of femoral stems—using both conventional and robot-assisted methods to optimize implant alignment, reduce complications, and improve long-term outcomes. A strong emphasis is placed on imaging diagnostics, particularly plain radiography, to enhance accurate diagnosis and treatment planning in hip pathology.

15At a mean of 4.4 years postoperatively, we found that open synovectomy and removal of loose bodies for the treatment of primary synovial osteochondromatosis of the hip is a reliable procedure that can effectively relieve symptoms. Our results also indicated that synovial osteochondromatosis may recur in patients with extensive involvement who are treated with synovectomy alone without dislocation of the hip; however, surgical complications are more likely to occur in patients managed with anteri
Plain radiographic examination is a fundamental approach to the diagnosis and treatment decision-making of the hip. A thorough understanding of standard radiographic techniques, radiographic anatomy, and disease patterns affecting the hip can be helpful in improving diagnostic accuracy. This article reviews the standard protocols used to obtain radiographic projections of the hip and addresses specific signs and various radiographic measurements used to adequately and reliably recognize structur
The present study suggested that robot-assisted short stem THA could increase the accuracy of stem alignment, improve leg length equality, and help reduce the risk of intraoperative femoral fracture as compared with manual rasping. However, the clinical outcome scores did not differ between the two groups at the time of short-term follow-up. Long-term follow-up is needed to determine whether there will be a long-term clinical relevance of robot-assisted implantation of short femoral stems in THA

BACKGROUND: Dysphagia is prevalent in geriatric patients, such as elderly hip fracture patients, and is associated with a poor prognosis. This study investigated (1) the prevalence of dysphagia based on clinical screening and a video-fluoroscopic swallowing study (VFSS), (2) the risk factors of dysphagia, and (3) the prognostic implications of dysphagia in elderly patients (≥ 65 years) undergoing hip fracture surgery. METHODS: In this retrospective study, data from 393 female and 153 male patien
Background: Primary synovial osteochondromatosis of the hip, a rare benign condition characterized by multiple intra-articular osteochondral loose bodies and synovial hyperplasia, may result in mechanical symptoms and degenerative arthritis if untreated. The purpose of this study was to report the results of arthrotomy alone or combined with anterior dislocation of the hip to perform synovectomy and removal of loose bodies in patients with this condition. Methods: We retrospectively reviewed a c
PURPOSE: The purpose of this study was to evaluate the results of cementless total hip arthroplasty (THA) using a 32 mm or larger Biolox®delta ceramic-on-ceramic (CoC) bearing in patients with osteonecrosis of the femoral head after a minimum of 5 years of follow-up. MATERIALS AND METHODS: We retrospectively analysed 44 patients (53 hips) who underwent cementless THA using Biolox®delta CoC bearing. There were 33 men (40 hips) and 11 women (13 hips) with the mean age of 49 years. A 36 mm head was
