  • Tearing of the acetabular labrum is a common cause of chronic hip pain. MR arthrography (MRA) of the hip is the imaging procedure of choice for the evaluation of acetabular labrum. Familiarity with the various imaging findings of MRA of the hip allows recognition of normal variants and differentiation from true pathologic conditions. This article comprehensively reviews the technical aspects and interpretation of MRA of the hip. The appearances of normal and abnormal labra in MRA are discussed. Potential pitfalls in labral tear interpretation, such as sulci around the hip, normal variants of the labrum and plicae, and osseocartilaginous and soft tissue lesions identified on MRA of the hip are also described.

  • The purpose of this meta-analysis is to compare the postoperative outcomes and complications of labral repair with those of labral reconstruction. An electronic search strategy was conducted from 1986 until August 2023 using the following databases: PubMed, Cochrane, and Google Scholar (pages 1-20). The primary objectives included the postoperative clinical outcomes determined by the number of patients who reached minimal clinical important difference (MCID) on the visual analog scale (VAS), modified Harris hip score (mHHS), Hip Outcome Score-Sports Subscale (HOS-SS), Hip Outcome Score-Activities of Daily Life (HOS-ADL), and International Hip Outcome Tool-12 (iHOT-12). In addition, analysis of the rate of revision arthroscopy, the rate of conversion to total hip arthroplasty (THA), the postoperative VAS, mHHS, HOS-SS, HOS-ADL, iHOT-12, nonarthritic hip score (NAHS), patient satisfaction, lower extremity function scale (LEFS), and the SF-12 (12-item shortform) was also performed. Any differences arising between the investigators were resolved by discussion. Seventeen studies were relevant to the inclusion criteria and were included in this meta-analysis. A higher rate of patients who reached MCID in the mHHS (P=0.02) as well as a higher rate of revision arthroscopy was observed for labral repair (P=0.03). The remaining studied outcomes were comparable. Despite the greater predictability of success in the reconstruction group, conduct of additional studies will be required for evaluation of the benefits of such findings. In addition, labral reconstruction is more technically demanding than a labral repair.

  • As the instruments as well as techniques for hip arthroscopy have developed, the interests and understandings of acetabular labral tear have also increased. As a consequence, the diagnosis itself was increased. However, it is still difficult to be diagnosed accurately in an ordinary clinic. In this brief review, the clinical and radiological characteristics and diagnostic implications of acetabular labral lesions were described to help the surgeon to make a right decision.

  • To minimize CT examination for Hip FAI diagnosis and operation plan. also, whether the MRI 3D images can replace Hip Clock face image was evaluated when performing Hip FAI MRI by using additional 3D image. This study analyzed Hip MRI and 3D Hip CT images of 31 patients in this hospital. For the purpose of evaluating the images, one orthopedic surgeon and one radiology specialist reconstructed Clock face, at MR and CT modality, by superior 12 o'clock, labrum front 3 o'clock, and the other side 9 o'clock, centering on Hip joint articular transverse ligament 6 o'clock. Afterwards, by the Likert Scale 5 point scale (independent t-test p<0.005), this study evaluated the check-up of A. retinacular vessel, B. head neck junction at 11 o'clock, A. Epiphyseal line, B. Cam lesion at 12 o'clock, and Cam lesion, Posterior Cam lesion at 1,2,3 and 4 o'clock. As for the verification of reliability among observers, this study verified coincidence by Cohen's weighted Kappa verification. As a result of Likert scale for the purpose of qualitative evaluation about the image, 11 o'clock A. retinacular vessel MR average was $3.69{\pm}1.0$ and CT average was $2.8{\pm}0.78$. B. head neck juncton didn't have a difference between two observers (p <0.416). 12 o'clock A. Epiphyseal line MR average was $3.54{\pm}1.00$ and CT average was $4.5{\pm}0.62$(p<0.000). B. Cam lesion didn't have a difference between two observers (p <0.532). 1,2,3,4 Cam lesion and Posterior Cam lesion were not statistically significant (p <0.656, p <0.658). As a result of weighted Kappa verification, 11 o'clock A.retinacular vessel CT K value was 0.663 and the lowest conformity. As a result of coincidence evaluation on respective item, a very high result was drawn, and two observers showed high reliability.

  • Purpose : We analyzed the effectiveness of arthroscopic diagnosis and treatment for painful hip in young patients caused by labral tear or synovial disease. Materials and Methods : From May 1997 to June 1998,7 young patients who had painful hip were diagnosed by history, physical examination, radiologic studies(including plain films, MRI, MR arthrogram) and arthroscopy. We treated the lesions by arthroscopic surgery and followed up for more than 1 year. Results : On arthroscopy, the labrum was torn in 6 cases and chronic synovitis was found in 1 case. After arthroscopic surgery, pain was eliminated completely in 5 cases and mild pain remained in 2 cases, respectively. But there was no limitation in activities of daily living and athletic performances. Conclusion : Arthroscopy is effective in diagnosis and treatment of labral tears and synovial diseases in young patients.
