Background: Preventing severe arthrogenic muscle inhibition (AMI) after knee injury is critical for better prognosis. The novel Sonnery-Cottet classification of AMI enables the evaluation of AMI severity but requires validation. This study aimed to investigate the electromyography (EMG) patterns of leg muscles in the examination position from the classification during isometric contraction to confirm its validity.

Methods: In patients who underwent isolated lateral MAT, quantitative MRI T2 mapping was conducted preoperatively and postoperatively with at minimum follow-up of 7 years to assess the articular cartilage status. On the sagittal section image bisecting the lateral femoral condyle, the weight-bearing portions of the femoral and tibial articular cartilage were divided into 3 segments each-6 segments in total-based on the meniscal coverage area.
Article Synopsis
- The study aimed to examine the characteristics of failed meniscal allografts within the first year after surgery, focusing on differences between lateral and medial transplantations.
- Researchers reviewed patient records from 2005 to 2018 and defined anatomical failure based on significant tears in the grafts.
- Results showed that lateral grafts often experienced meniscocapsular separation, predominantly in the midbody, while medial grafts mostly had root tears in the posterior area, highlighting significant differences in failure patterns and locations between the two types.
Purpose: To verify whether the distance from the hinge point to the tibial cortex affects the occurrence time and characteristics of the lateral hinge fracture (LHF) in medial open-wedge high tibial osteotomy.
Methods: We retrospectively reviewed 171 knees in 171 patients (121 women, 50 men; mean age, 53.9 years; range, 36-67 years) who had undergone medial open-wedge high tibial osteotomy with locking plate fixation between January 2011 and December 2020.
Article Synopsis
- The study investigates the impact of graft extrusion after meniscal allograft transplantation (MAT) on the quality of knee articular cartilage, which hasn't been deeply analyzed before.
- Researchers compared outcomes between 105 patients with and without graft extrusion using MRI scans and T2 mapping over a mean follow-up period of 3.2 years.
- Results indicated that patients in the nonextrusion group showed significant improvements in cartilage quality and clinical function, while the extrusion group did not demonstrate any notable changes.
Purpose: This study aimed to assess the cartilage status in patients who underwent isolated lateral meniscus allograft transplantation (MAT) using preoperative and postoperative quantitative 3-T magnetic resonance imaging T2 mapping at midterm follow-up period.
Methods: Patients who underwent lateral MAT without cartilage treatment procedures between 2010 and 2019 were assessed by quantitative magnetic resonance imaging preoperatively and postoperatively. On the sagittal section image following the center of the lateral femoral condyle, the weight-bearing area of the articular cartilage was divided into 6 segments based on the meniscal coverage area from anterior to posterior direction.
Article Synopsis
- The study investigated the survival rates and prognostic factors for medial meniscal allograft transplantation (MAT) by reviewing records of 78 patients from 1996 to 2018.
- Anatomic failure occurred in 24.4% of patients, while clinical failure was noted in 9.0%, with 10-year survival rates for anatomic and clinical outcomes at 73.89% and 87.90%, respectively.
- High-grade cartilage lesions were linked to higher anatomic failure risk, but no significant associations were found for clinical failure rates based on patient factors.
Periimplant osteolysis does not affect the outcome of rotator cuff repair: a systematic review and meta-analysis.

Purpose: The goal of this study was to perform a systematic review and meta-analysis to compare the clinical and radiologic outcomes of rotator cuff repair, depending on the presence of developed periimplant osteolysis (PIO) after using suture anchors.
Methods: The electronic databases of MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched for articles published up until October 2019 to find relevant articles comparing the outcomes of rotator cuff repair between the periimplant osteolysis group and non-periimplant osteolysis group. Data searching, extraction, analysis, and quality assessment were performed according to the Cochrane Collaboration guidelines.
Arthroscopic treatment for intratendinous rotator cuff tear results in satisfactory clinical outcomes and structural integrity.

Purpose: This study aimed to evaluate the clinical outcomes and structural integrity of arthroscopic repair of intratendinous rotator cuff tear.
Methods: Patients who were diagnosed with an intratendinous tear but in whom conservative treatment failed were selected and underwent arthroscopic repair. Between 2008 and 2014, a total of 30 patients (6 men, 24 women; mean age, 59 ± 3.
Background: While reconstruction of soft tissue defects is the common purpose, surgical reconstructions of upper extremities and lower extremities have different goals in terms of functional and aesthetic outcomes. The purpose of the current study was to compare and analyze differences between reconstructions of upper extremities and lower extremities using an anterolateral thigh (ALT) flap.
Methods: We analyzed 74 patients who underwent reconstructions of upper extremities and lower extremities using an ALT flap from October 2006 to August 2012 (upper extremities, 45 cases; lower extremities, 29 cases).
