Background: Tibial tuberosity-trochlear groove (TT-TG) distance is important in the assessment and treatment of patellofemoral disorders. However, normal and pathological TT-TG values have not been established in Koreans. The purpose of this study was to evaluate the TT-TG distance in the Korean population using lower leg rotational profile computed tomography (CT) scans. Methods: One hundred rotational profile CT scans were retrospectively collected from patients without knee joint problems aged between 25 to 82 years. TT-TG distances were measured, and statistical analysis was performed. Each CT scan was measured twice in a blinded, randomized manner by three reviewers. Patients with pre-existing knee joint problems were excluded from the study; hence 15 of the 100 patients were excluded because of deformity or unreadable CT scans. Thus, 85 of the 100 patients were included in the study. Results: Interobserver and intraobserver reliability of TT-TG distance measurements was good. The median TT-TG distance for this Korean population was 11.24 mm (mean, 10.24 ± 0.8 mm). TT-TG distance measured nearly 2 mm less on rotational profile CT scans. Conclusions: Some of the TT-TG distances on rotational profile CT scans were significantly correlated, indicating that they could be accepted. Furthermore, the values on CT scans showed good reliability. In this study, the TT-TG distance in normal Korean people was approximately 10.24 mm without significant differences in TT-TG values between genders.

어머니의 인성특성, 양육행동, 유아의 정서조절능력과 또래유능성 간의 관계
송은교,정정희,정효진 한국어린이문학교육학회 2018 어린이문학교육연구 Vol.19 No.4
The purpose of this study was to examine the pathway of mothers' personality, parenting behavior, young children's emotional regulation affecting peer competence. In this study, the subjects were 341 young children (170 boys, 171 girls) 4 to 5 years of age and their mothers lived in Ulsan. The major results of this study were as follows;First, as far as the correlations among mothers' personality, parenting behavior, young children's emotional regulation and peer competence, it was found that warm maternal parenting behavior and young children's emotional regulation were positively related to peer competence. Second, mothers' personality showed an indirect effect on young children's emotional regulation through maternal parenting behavior. Extroversion among the mothers' personalities affected warm maternal parenting behavior and young children's emotional regulation in that order. Third, parenting behavior showed an indirect effect on peer competence, mediated by young children's emotional regulation. It was found that a higher affectionate parenting behavior among affectionate maternal parenting behaviors became higher for young children's emotional regulation which affected peer competence. Lastly, mothers' personality showed an indirect effect on peer competence, mediated by maternal parenting behavior and young children's emotional regulation. In other words, extroversion among the mothers' personalities had a positive influenced on affectionate maternal parenting behavior and young children's emotional regulation subsequently. As a result, peer competence, which is positively influenced has an indirect effect on young children's emotional regulation. 본 연구는 어머니의 인성특성, 양육행동, 유아의 정서조절과 또래유능성 간에 관계를 살펴보고 각 변인들이 또래유능성에 어떠한 경로로 영향을 미치는지 알아보고자 하였다. 연구대상자는 울산 지역에 있는 만 4-5세 유아와 그들의 어머니 341명이다. 연구결과는 첫째, 또래유능성과 관련하여 어머니의 인성특성, 양육태도, 유아 정서조절 능력의 변인들 중 어머니의 온정적 양육태도와 유아의 정서조절능력이 높은 상관관계를 보여주었다. 둘째, 어머니의 인성특성은 양육행동을 매개로 하여 유아의 정서조절능력에 간접적인 영향을 주는 것으로 나타났으며, 어머니의 양육행동은 유아의 정서조절능력을 매개로 유아의 또래유능성에 간접적으로 영향을 미치고 있었다. 아울러 어머니의 인성특성은 어머니의 양육행동과 유아의 정서조절능력을 매개로 하여 또래유능성에 영향을 주는 것으로 나타났으며, 유아의 내적 특성인 정서조절능력은 매개역할을 함과 동시에 직접적인 영향을 미치는 것으로 나타났다.

Causes of Aseptic Persistent Pain after Total Knee Arthroplasty
임홍안,송은교,선종근,박경순,신영주,양홍연 대한정형외과학회 2017 Clinics in Orthopedic Surgery Vol.9 No.1
Background: Persistent pain after total knee arthroplasty (TKA) is dissatisfying to the patient and frustrating to the surgeon. The purpose of this study is to evaluate the aseptic causes and clinical course of intractable pain following TKA. Methods: Of the total 2,534 cases of primary TKA reviewed, 178 cases were classified as having aseptic persistent pain that was not resolved within 1 year after surgery. Except for the cases with periprosthetic fracture (56 knees), 122 cases of aseptic painful TKA were divided into two groups: intra-articular group (83 knees) and extra-articular group (39 knees). Results: In the intra-articular group, the main reasons for pain were aseptic loosening (n = 40), polyethylene wear (n = 16), instability (n = 10), recurrent hemarthrosis (n = 5), patellar maltracking (n = 4), tendon ruptures (n = 4), and stiffness (n = 2). In the extraarticular group, 10 knees (25.6%) were found to have nerve entrapment in the spine, 6 knees (15.4%) were found to have hip osteoarthritis or femoral head avascular necrosis. The reasons for persistent knee pain in the remaining 23 knees (59.0%) still remain elusive. Conclusions: Persistent pain after TKA originated from pathology of extra-articular origin in a considerable number of cases in this study. Therefore, it is important to perform thorough preoperative evaluations to reduce pain resulting from extra-articular causes. Furthermore, meticulous surgical procedures and optimal alignment are required to reduce pain of intra-articular origin related to implant wear, instability, and patellar maltracking.
