conclusions both l-prp and l-prf could be used to effectively promote the healing of articular cartilage defects of the knee. results mean macroscopic scores of the treated defects were higher than the controls at all sampling times with significant differences (p < 0.05) observed between l-prf treated and control defects (10.13 vs. 8.37) and l-prp treated and control defects (10 vs. 8.5) at 4 ...

objective(s): protein kinase c (pkcα) is involved in modulating articular chondrocytes apoptosis induced by nitric oxide (no). hyaluronic acid (ha) inhibits nitric oxide-induced apoptosis of articular chondrocytes by protecting pkcα, but the mechanism remains unclear. the present study was performed to investigate the effects and mechanisms of pkcα regulate protective effect of hyaluronic acid....

background: integrins are a family of transmembrane proteins that allow communication between the extracellular matrix and the interior of cells. chondrocytes, cells of articular cartilage, express integrins and these molecules appear to have a variety of roles including mechanotransduction. integrins are known to associate with a number of accessory molecules such as cd147 that may act to regu...

background:   various drugs are administered intra-articularly to provide postoperative analgesia after arthroscopic knee surgery. the purpose of this study was to assess the analgesic effects of intra-articular injection of a dexmedetomidine   following knee arthroscopy.     methods:   forty six patients schadualed for arthroscopic knee surgery under general anaesthesia, were randomly devided ...

background: arthroscopic intervention is very common for conducting orthopedic surgeries. after a knee arthroscopic surgery, different drugs are used through intra-articular administration to induce analgesia. the aim of this study was to evaluate analgesic effects of bupivacaine (marcaine), bupivacaine plus midazolam, and bupivacaine plus fentanyl in reducing pain after knee arthroscopic surge...

introduction intra-articular injections of platelet rich plasma (prp) for the treatment of knee osteoarthritis have been shown to reduce pain and improve joint function. the aim of this study is to examine the joint function by adding intra-articular growth hormone to platelet rich plasma. this study was performed on the individuals with knee osteoarthritis and under ultrasound guidance. conclu...

  Objective(s): Osteoarthritis is one of the most common diseases in middle-aged population in the world. Cartilage tissue engineering (TE) has been presented as an effort to introduce the best combination of cells, biomaterial scaffolds and stimulating growth factors to produce a cartilage tissue similar to the natural articular cartilage. In this study, the chondrogenic potential of adipose d...
