The aim of this study was to assess the reproducibility and validity
of cross table radiographs for measuring the anteversion of the
acetabular component after total hip arthroplasty (THA) and to compare
it with measurements using CT scans. A total of 29 patients who underwent THA between June 2010 and
January 2016 were included. There were 17 men and 12 women. Their
mean age was 43 years (26 to 65). Seven patients underwent a bilateral
procedure. Thus, 36 THAs were included in the study. Lateral radiographs
and CT scans were obtained post-operatively and radiographs repeated
three weeks later. The anteversion of the acetabular component was
measured using the method described by Woo and Morrey and the ischiolateral
method described by Pulos et al and these were compared with the
results obtained from CT scans.Aims
Patients and Methods
Transportal technique of femoral drilling allows the femoral tunnel to be placed in anatomic location. The study was conducted to evaluate the orientation of ACL graft performed by two different techniques and compared to orientation of native ACL. 50 patients (Group A) underwent ACL reconstruction with transtibial technique using transfix on the femoral side and 30 patients (Group B) underwent ACL reconstruction with transportal technique using endobutton. We used quadrupled hamstrings graft and tibial fixation was achieved with bio-absorbable screws. All patients were evaluated with 3 Tesla MRI at 6 months post-operatively and femoral tunnel angle in coronal plane (FTA), tibial tunnel angle (TTA) in sagittal plane, graft angle in coronal plane (GA coronal), graft angle in sagittal plane (GA sagittal), and graft- Blumensaat line angle (GBLA) were measured. A control group of patients (Group C, n=50)was also included to evaluate the orientation of native ACL.Introduction

Transportal technique of femoral drilling allows the femoral tunnel to be placed in anatomic location. The study was conducted to evaluate the orientation of ACL graft performed by two different techniques and compared to orientation of native ACL. 50 patients (Group A) underwent ACL reconstruction with transtibial technique using transfix on the femoral side and 30 patients (Group B) underwent ACL reconstruction with transportal technique using endobutton. We used quadrupled hamstrings graft and tibial fixation was achieved with bioabsorbable screws. All patients were evaluated with 3 Tesla MRI at 6 months post-operatively and femoral tunnel angle in coronal plane (FTA), tibial tunnel angle (TTA) in sagittal plane, graft angle in coronal plane (GA coronal), graft angle in sagittal plane (GA sagittal), and graft-Blumensaat line angle (GBLA) were measured. A control group of patients (Group C, n=50)was also included to evaluate the orientation of native ACL. The femoral tunnel angle (FTA) was significantly lower in group B as compared to group A, 54.03±5.05 vs 71.6±6.02, p<0.05. The tibial tunnel angle (TTA) was similar in group A and B, 65±5.2 vs. 62.9±4.5, p>0.05. Graft angle in coronal plane (GA coronal) was significantly lower in group B when compared to group A, 62.4±5.6 vs 72.5±5.5, p<0.05, and there was no significant difference between group B and C. Similarly graft angle in sagittal plane (GA sagittal) in group B was found to be significantly lower as compared to group A and similar to group C, 51.2±4.3 vs 65.3±3.6, p<0.05. The graft-Blumensaat line angle (GBLA) was significantly lower in group B as compared to Group A, 8.6±1.4 vs 13.5±1.2, p<0.05. The orientation of the reconstructed ligament was found to be closer to the native ACL in transportal technique of femoral drilling.
We compared the safety and outcome of one-stage bilateral total hip arthroplasty with those of a two-stage procedure during different admissions in a prospective, randomised controlled trial in an Asian population. Of 168 patients included in the study, 83 had a single- and 85 a two-stage procedure. Most of the patients (59.9%) suffered from inflammatory arthritis. The intra-operative complications, early systemic complications, the operating time, positioning of the components, the functional score, restoration of limb length and survival rates at 96 months were similar in the two groups. The total estimated blood loss was significantly lower in patients undergoing a one-stage procedure than in patients who had a two-stage procedure, but the transfusion requirements were significantly higher in the former group (p = 0.001). The hospital stay was significantly shorter in the one-stage group, 7.25 days (
