Arthrofibrosis And loose plate on Stryker prosthesis Posted by mel 726 @mwatts91757 , Mar 5 7:09pm I Went to my 3rd orthopedist to discuss removal of scar tissue he explained to me that my bone scan revealed that there may be a plate loose. Therefore, we investigated the use of a drug scaffold for sustainable intra-articular delivery of therapeutic doses of celecoxib. and Abdel, {Matthew P.}". As she said, my name's Trevor Murray, I'm an adult reconstruction surgeon here at the Cleveland Clinic. ... (Mayo Clinic Rochester IRB #09–000115) prior to enrollment. The shoulder, elbow, and knee are particularly susceptible to the condition. The nonsteroidal anti-inflammatory drug, celecoxib, may have therapeutic benefits for arthrofibrosis, but current methods for its local delivery (e.g., biologically derived microspheres) are not translatable to immediate clinical use. The nonsteroidal anti-inflammatory drug, celecoxib, may have therapeutic benefits for arthrofibrosis, but current methods for its local delivery (e.g., biologically derived microspheres) are not translatable to immediate clinical use. Synovitis causes usually have a link to incidents of trauma and related health conditions. The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. The diversity of molecular pathways involved in arthrofibrosis disease progression suggest that effective treatments for arthrofibrosis may require a multimodal approach to counter the complex cellular mechanisms that direct disease pathogenesis. Arthrofibrosis After Periarticular Fracture Fixation. These joints can include the knee, shoulder, ankle, wrist, and hip. Conclusions: This study characterized the novel use of collagen scaffolds for intra-articular drug delivery to treat arthrofibrosis. Early postoperative motion should be promoted whenever possible. Scaffolds exhibit celecoxib release through an initial burst release followed by sustained release of antifibrotic doses over 7 days. I had knee replacement surgery 6 weeks ago . The nonsteroidal anti-inflammatory drug, celecoxib, may have therapeutic benefits for arthrofibrosis, but current methods for its local delivery (e.g., biologically derived microspheres) are not translatable to immediate clinical use. Little background, I was actually a resident here from 2004 to 2010, where I did a residency in orthopedic surgery, and then I went to Chicago for a year to do a fellowship, which was a year of specialization in total hip and total knee replacements. Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by stiffness and pain in your shoulder joint. William H. Trousdale, Christopher G. Salib, Nicolas Reina, Eric A. Lewallen, Anthony Viste, Daniel J. Berry, Mark E. Morrey, Joaquin Sanchez-Sotelo, Andre J. Overview. Statistical analysis The cumulative incidence of ACL reconstruction and arthrofibrosis over time was estimated using the Kaplan– Meier method. Arthrofibrosis is an abnormal histopathologic response, is debilitating for patients, and poses a substantial unsolved clinical challenge. Eluted concentrations of celecoxib were examined for toxicity (live/dead staining) and profibrotic gene expression (real-time-quantitative polymerase chain reaction) in rabbit knee capsular fibroblasts in vitro. There were 3 distinct groups for RNA-seq. Van Wijnen, Matthew P. Abdel, Research output: Contribution to journal › Article › peer-review. Trousdale, William H. ; Salib, Christopher G. ; Reina, Nicolas ; Lewallen, Eric A. ; Viste, Anthony ; Berry, Daniel J. ; Morrey, Mark E. ; Sanchez-Sotelo, Joaquin ; Van Wijnen, Andre J. There were 3 distinct groups for RNA-seq. Lie down and place your knee and foot on a pillow so that your entire lower leg is elevated to ease swelling. Early postoperative motion should be promoted whenever possible. Manipulations under anesthesia are effective for a period of time in certain fracture patterns, and open or arthroscopic surgical debridements should be reserved for the patient for whom nonoperative modalities fail and who has a clinically significant deficit. 33, 34.

This excessive scar tissue causes shrinkage and tightening of the capsules of the joints and at times even the tendons which are surrounding the joint tend to get stiff due to this scar tissue. As an orthopedic clinician-scientist with broad-based training in orthopedic surgery, biomechanics and biochemistry, Matthew P. Abdel, M.D., is interested in studying clinically relevant pathologies while considering the functional impact on patients. Dive into the research topics of 'Arthrofibrosis After Periarticular Fracture Fixation'. The Effects of Scar Tissue After Surgery. Arthrofibrosis (from Greek: arthro- joint, fibr- fibrous and -osis abnormality) is an inflammatory condition that leads to the production of excessive scar tissue in or around major joints. Many risk factors for the development of arthrofibrosis cannot be controlled by the patient or surgeon. Results: Sustained concentrations of celecoxib eluted from the membrane over 7 days from both a wet and dry scaffold, with a burst release (30-45%) of celecoxib in the first 2 h. Rabbit cells treated with eluted concentrations experienced a toxic response to the burst release doses, and inhibitory effects on profibrotic genes were seen in response to the sustained doses eluted from the scaffold. Results: Sustained concentrations of celecoxib eluted from the membrane over 7 days from both a wet and dry scaffold, with a burst release (30-45%) of celecoxib in the first 2 h. Rabbit cells treated with eluted concentrations experienced a toxic response to the burst release doses, and inhibitory effects on profibrotic genes were seen in response to the sustained doses eluted from the scaffold. Scaffolds exhibit celecoxib release through an initial burst release followed by sustained release of antifibrotic doses over 7 days. ; R01 AR072597). Materials and Methods: Celecoxib was eluted from clinically approved biodegradable collagen membranes over 7 days as measured by UV spectroscopy and high-performance liquid chromatography/mass spectroscopy. A Drug Eluting Scaffold for the Treatment of Arthrofibrosis. (1) Background: Arthrofibrosis is a common cause of patient debility and dissatisfaction after total knee arthroplasty (TKA). note = "Funding Information: We thank members of the orthopedic research laboratories and especially Afton K. Limberg, BS, Meagan E. Tibbo, MD, Amel Dudakovic, PhD, and Roman Thaler, PhD, for their expertise and guidance. Mayo Clinic Location Status Contact; Rochester, Minn. Mayo Clinic principal investigator. Many risk factors for the development of arthrofibrosis cannot be controlled by the patient or surgeon. Go to Conclusions: This study characterized the novel use of collagen scaffolds for intra-articular drug delivery to treat arthrofibrosis. AB - Introduction: The inflammatory cascade and production of prostaglandins may play a role in the pathogenesis of arthrofibrosis, a debilitating condition after joint … Flexion contractures of more than 7 or 8 degrees compared to the opposite normal limb have been shown to limit patients function, lead to early arthritis and can cause se… Thus, collagen scaffolds are promising for clinician-directed treatment of arthrofibrosis. @article{da750bf2c2b54d2dbf5d85749a24267b. Early postoperative motion should be promoted whenever possible.

Manipulations under anesthesia are effective for a period of time in certain fracture patterns, and open or arthroscopic surgical debridements should be reserved for the patient for whom nonoperative modalities fail and who has a clinically significant deficit.

Results: Sustained concentrations of celecoxib eluted from the membrane over 7 days from both a wet and dry scaffold, with a burst release (30-45%) of celecoxib in the first 2 h.
