Reversibility of Supraspinatus Muscle Atrophy in Tendon-Bone Healing After Arthroscopic Rotator Cuff Repair.

Background: To date, there are few reports of the definite reversibility of rotator cuff muscle atrophy after repair.

Purpose: To evaluate the reversibility of rotator cuff muscle atrophy after successful arthroscopic repair.

Study Design: Case series; Level of evidence, 4.

Is Total Knee Arthroplasty a Viable Treatment Option in Octogenarians with Advanced Osteoarthritis?

Purpose: This study directly compared clinical assessment scores and short-term systemic complications after total knee arthroplasty (TKA) between a group of patients aged 80 or older (141 patients) and another group of patients aged between 65 and 70 years (616 patients) with advanced osteoarthritis.

Materials And Methods: We retrospectively investigated 757 osteoarthritic patients who underwent primary TKA from January 2007 to January 2011 with a follow-up of 1 year. The surgery was performed using an extramedullary alignment guide instrument without invasion of the intramedullary canal to decrease embolic load and blood loss.

Infrapatellar fat pad preservation reduces wound complications after minimally invasive total knee arthroplasty.

Introduction: The aim of this study was to determine whether pain intensity and wound complication rates differ between patients with and without preservation of the infrapatellar fat pad (IPFP) after minimally invasive total knee arthroplasty (TKA). The authors also sought to determine whether IPFP preservation affects operation time.

Materials And Methods: This retrospective study included 448 knees with primary TKA.
