The current study demonstrated partial fibulectomy at 12 cm above lateral malleolus results in decreasing pressure in knee medial compartment and increasing pressure in knee lateral compartment. Further studies are needed to evaluate the clinical importance of partial fibulectomy.

Objective:The purpose of this study was to evaluate the results of single bundle and double bundle surgical techniques for anterior cruciate ligament (ACL) reconstruction.Methods:In this study, all single bundle and double bundle ACL reconstruction surgeries that were done in our university hospital from January 2008 to December 2012 were enrolled. All patients were followed at 2,6,12, 24 weeks and 1 a 2 years post operatively. On last follow up all patients were evaluated by clinical examination, KT-1000 and Lysholm questionnaire.Results:Seventy five patients were operated using single bundle and eighty five patients with double bundle technique. Fifty seven percent of patients in single bundle and 80% of patients in double bundle group had experienced pain during follow-up period. None of cases had knee extension or flexion loss. The average side to side differences using KT-1000 was 3.5 ± 0.38 (2.9-4.1) millimeters in single bundle group and 3.39 ± 0.39 (2.8-4) millimeters in double bundle group. These results showed no significant difference between two groups (P= 0.31). Lysholm score improved significantly in both groups, but there was no significant difference between them.Conclusion:According to this study the clinical results of single bundle ACL reconstruction was similar to double bundle reconstruction in short term follow up. Further studies are needed to evaluate the long term results.

Background: Male patients undergoing total joint arthroplasty have a higher risk of periprosthetic joint infection (PJI) compared with female patients. The exact reason for this finding is not well known. This study aimed to determine if patients with symptomatic benign prostatic hyperplasia (BPH) are at increased risk of PJI. Methods: A total of 12,902 male patients who underwent primary or revision total joint arthroplasty from January 2006 to April 2017 were retrospectively identified. The mean patient age was 62.47 years and the mean patient body mass index was 30.1 kg/m2. The majority of patients were Caucasian or African American. Most surgical procedures involved the hip joints (57.8%) and were primary arthroplasties (86%). Of these patients, 386 (3%) had symptomatic BPH. Among this group, 250 patients with symptomatic BPH were identified and were matched in an approximate 1:3 ratio with 708 control patients. Using the International Consensus Meeting criteria, patients who developed PJI were identified. Results: The PJI rate was 7.9% in the symptomatic BPH group and 2.8% in the control group. Multivariate regression analysis in unmatched groups showed that symptomatic BPH was a strong independent risk factor for PJI. After matching for variables related to outcomes, symptomatic BPH remained a significant risk factor for PJI (p = 0.01). Conclusions: Patients with symptomatic BPH had a higher risk of PJI compared with the control patients. This may partly explain the higher rate of PJI that is seen in male patients. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
