Objective: Magnesium sulfate has been shown to provide analgesia when administered into the knee joints. The aim of this study was to evaluate the histopathological effects of intraarticular administration of magnesium sulfate in the rat knee joint. Design: A total of 50 rats were given 0.25ml of magnesium sulfate (10%) by injection into the right knee joint and 0.25ml of 0.9% saline solution b...

INTRODUCTION Microfracture does not properly repair full-thickness cartilage defects. The purpose of this study was to evaluate the effect of intraarticular injection of the small-molecule compound kartogenin (KGN) on the restoration of a full-thickness cartilage defect treated with microfracture in a rabbit model. METHODS Full-thickness cartilage defects (3.5 mm in diameter and 3 mm in depth...

OBJECTIVES Hyaluronic acid (HA) is used for intraarticular treatment of hip osteoarthritis (OA). The objective of this study was to determine the efficacy of intraarticular injection of HA through a lateral approach under fluoroscopic control for advanced hip OA. METHODS The study included 21 patients with advanced hip OA. All patients received 2.5 ml HA injection once a week for 3 weeks by l...

OBJECTIVES The purpose of this study is to compare the effects of bee venom pharmacopuncture (BVP) therapy according to the methods used to treat knee osteoarthritis (OA): intra-acupoint combined with intra-articular injection, intra-acupoint injection, and intra-articular injection. METHODS A total of 69 patients were recruited by the Department of Acupuncture & Moxibustion at Dong- Eui Orie...

Lumbar facet joint (LFJ) osteoarthritis (OA) is an important etiology of low back pain. Several animal models of LFJ OA have been established using intraarticular injection of various chemicals. This study aimed to establish a rat model of LFJ OA using urinary plasminogen activator (uPA). Sprague-Dawley rats were treated with intraarticular injection in the L5-L6 facet joints with uPA (OA group...

Background:  Tranexamic acid (TXA) has received extensive attention in management of blood loss in orthopedic surgeries. However, the ideal method of TXA administration is still controversial. This study aims to determine whether intraarticular injection of TXA reduces blood loss after total knee arthroplasty (TKA).   Methods:  Through a retrospective case-control study consecutive TKA patients...
