The Impact of Patellar Position on Mediolateral Joint Gap in Cruciate-Retaining and Posterior-Stabilized Total Knee Arthroplasty: A Prospective Study.

Background: This prospective study aimed to investigate the influence of patellar position (ie, eversion, lateralization, and reduction) on medial and lateral gap measurements during total knee arthroplasty (TKA) in both cruciate-retaining (CR) and posterior-stabilized (PS) TKA designs.

Methods: The present work analyzed 50 knees with primary osteoarthritis that underwent TKA between July and November 2019. Medial and lateral gaps were measured at different knee flexion angles (0°, 45°, 90°, and 120°) in 3 patellar positions after sequentially inserting CR type and PS type trial component in the same knee.

Three-Dimensional Morphometric Analysis of Penetrative Depth and Size of Nonarthritic and Degenerative Arthritic Glenoids: Implications for Glenoid Replacement in Shoulder Arthroplasty.

Background: Shoulder arthroplasty is technically demanding and relies heavily on the precision of surgical techniques. Proper glenoid component sizing plays a crucial role in successful shoulder arthroplasty. We measured the size and penetrative depth of the glenoid for peg or screw fixation in nonarthritic and degenerative arthritic shoulders by using three-dimensional computed tomography to determine the reference dimensions of the glenoid in nonarthritic and degenerative arthritic shoulders.

Arthroscopic repair of horizontal meniscal cleavage tears with marrow-stimulating technique.

Purpose: The purpose of this study was to evaluate patients after arthroscopic repair of meniscal horizontal tears with a marrow-stimulating technique through clinical signs and second-look arthroscopy.

Methods: We retrospectively reviewed a consecutive series of 32 meniscal repairs with horizontal cleavage tears and evaluated them through clinical assessment and second-look arthroscopic examinations. Arthroscopic meniscal repair and a marrow-stimulating technique were performed.

Efficacy of magnetic resonance imaging evaluation for meniscal tear in acute anterior cruciate ligament injuries.

Purpose: The objective of this study was to compare the preoperative magnetic resonance imaging (MRI) diagnostic rates of meniscal injuries combined with acute anterior cruciate ligament (ACL) injuries, as well as traumatic meniscal injuries without ACL injuries.

Methods: From January 2005 through April 2013, 208 patients who underwent ACL reconstruction and 1,334 patients with traumatic meniscal tear injuries were examined by MRI and arthroscopy. Patients with chronic ACL injuries, revisions, fracture histories, or multiple-ligament injuries and patients with Outerbridge degenerative changes of grade 3 or greater were excluded, yielding 159 patients and 621 patients in the 2 groups, respectively.

ACL Reconstruction with Autologous Hamstring Tendon: Comparison of Short Term Clinical Results between Rigid-fix and PINN-ACL Cross Pin.

Purpose: To compare the short term clinical results of anterior cruciate ligament (ACL) reconstruction with autologous hamstring tendon between Rigid-fix and PINN-ACL Cross Pin for femoral side fixation.

Materials And Methods: 127 patients who underwent arthroscopic ACL reconstruction using autologous hamstring tendon and had been followedup for over than one year were enrolled for the present study. Rigid-fix was used in 71 cases (group 1), and PINN-ACL Cross Pin was used in 56 cases (group 2).

Delayed diagnosed stage 1, 2 distractive flexion injury of the cervical spine.

Study Design: Retrospective study.

Purpose: To examine the clinical and radiologic characteristics of patients with stage 1 and 2 distractive flexion injury according to Allen's classification and who were not diagnosed immediately after injury, and to analyze the outcomes of surgical treatments.

Overview Of Literature: For the diagnosis of stage 1 and 2 distractive flexion injury in the lower cervical spine, attention should be paid when performing radiographs as well as when interpreting the radiographs.

Surgical outcome of 2-stage management of multiple knee ligament injuries after knee dislocation.

Purpose: The purpose of this study was to determine the effectiveness of a new 2-stage surgical treatment for acute traumatic knee dislocation.

Methods: The study involved 15 knees in 14 patients treated between October 1997 and November 2001. The mean follow-up was 88.

Early results of high-flex total knee arthroplasty: comparison study at 1 year after surgery.

We compared clinical [including maximal flexion and range of motion (ROM)] and radiographical outcomes of high-flex versus conventional implants for total knee arthroplasty (TKA) after 1 year. We also analyzed the factors affecting postoperative ROM in high-flex implants. The high-flex group (n=90) had an average maximal flexion of 129.
