Comparison of Magnetic Resonance Imaging of Remnant Preserving versus Remnant Sacrificing Technique after Anterior Cruciate Ligament Reconstruction; Clinical Results and Second-Look Arthroscopic Findings: Pilot Study / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to clarify the difference between the remnant-preserving and remnant-sacrificing techniques in anterior cruciate ligament (ACL) reconstruction using stress test, functional score, 2nd look arthroscopy and magnetic resonance imaging (MRI). MATERIALS AND METHODS: Among 66 patients having anatomical ACL reconstruction with the fourstrand hamstring autograft using outside-in technique (FlipCutter(R)) for the femoral tunnel from April 2012 to April 2014, 23 patients who underwent 2nd look arthroscopy and MRI were included. The remnant-preserving group included 12 patients and the remnant-sacrificing group included 11 patients. The two groups were compared and analyzed with regard to stability (Stress test using GNRB(R), pivot shift test), functional assessment (International Knee Documentation Committee [IKDC] scale, Lysholm score, one leg hoop test), and the result of second-look arthroscopy and signal to noise quotient (SNQ) ratio of the graft in MRI. RESULTS: The two groups did not differ significantly in the stability test, IKDC scale, and Lysholm test. The remnant-preserving group showed significant improvement in one leg hoop test compared with the remnant-sacrificing group (p0.05). CONCLUSION: More than 12 months after surgery, the graft of the remnant-preserving group showed lower signal intensity compared to that of the remnant-sacrificing group by MRI evaluation. The remnant preserving technique has biological difference compared with the remnant sacrificing technique in human study.

Risk Factor of Depression after Amputation In Treatment of the Lower Extremity Open Fracture Associated with Severe Soft Tissue Injury / 대한정형외과연구학회지

PURPOSE: To evaluate the incidence rate and risk factors for depression after amputation in treatment of the lower extremity open fracture associated with severe soft tissue injury. MATERIALS AND METHODS: We carried out a retrospective case-control study of 30 patients, who underwent lower extremity amputation between March 2002 and February 2012 and subsequently followed up over 12 months. We classified the patients into two groups: group A (study group, depression expressed) and group B(control group, normal). The risk factors were then subdivided based on patient-related factors such as whether or not patients received psychiatric treatment, sociolopsychological environmental factors, and daily activities after recovery. RESULTS: The overall incidence rate of depression was 40%;20 patients were male, and 10 patients were female (66.7% and 33.3%, respectively). Age (odd ratio=1.14), Accompanying injury (odd ratio=2.06), underlying disease, Psychiatric treatment (odd ratio=44.73), sociopsychological environment (odd ratio=17.53),daily activities (odd ratio=8.76) were significant. CONCLUSION: We concluded that the risk factors for depression after amputation are age, accompanying injury, and underlying diseases, irrespective of whether or not patients received psychiatric treatment, and not associated with isolated sociopsychological environments, or hypoactivity of daily living.
