Partial Meniscectomy for Degenerative Medial Meniscal Root Tears Shows Favorable Outcomes in Well-Aligned, Nonarthritic Knees.

Background: Arthroscopic meniscectomy has been commonly performed for persistent pain caused by degenerative medial meniscal posterior root tears (MMPRTs). However, risk factors that affect long-term outcomes and joint survivorship after meniscectomy are unclear.

Purpose: To identify the risk factors associated with end-stage osteoarthritis after arthroscopic meniscectomy for degenerative MMPRT for middle-aged or elderly patients and to determine the joint survivorship according to the identified risk factors.

Rotator cuff surgery in patients older than 75 years with large and massive tears.

Background: The purpose of this study was to evaluate whether rotator cuff repair improves subjective and functional outcomes in patients aged ≥75 years.

Methods: From May 2005 to March 2013, 121 elderly patients who underwent rotator cuff repair for large and massive rotator cuff tears were evaluated retrospectively. Patients with an American Society of Anesthesiologists physical status classification system grade ≥4 were excluded.

Redisplacement of Distal Radius Fracture after Initial Closed Reduction: Analysis of Prognostic Factors.

Background: To evaluate risk factors of redisplacement and remind surgeons of key factors regarding conservative treatment of distal radius fracture.

Methods: A total of 132 patients who received conservative treatment for distal radius fractures between March 2008 and February 2011 were included in this study. Radial inclination, radial length, volar tilting angle, ulnar variance, fragment translation, and presence of dorsal metaphyseal comminution were measured on the X-rays taken immediately after reduction, one week after injury during the first follow-up outpatient clinic visit, and after the gain of radiological union.
