Platelet-rich plasma significantly improves outcomes in patients with tennis elbow

2013-03-21
(Press-News.org) (CHICAGO) – Platelet rich plasma (PRP) therapy has been used to manage pain associated with torn tendons, muscles and ligaments, mostly in athletes, at all levels. Though it has anecdotally been successful, the evidence to support its efficaciousness is weak. Researchers at the Rothman Institute at Jefferson participated in a multi-center randomized prospective study to evaluate the clinical value of PRP versus an active control group to determine its effectiveness in managing the pain and tenderness associated with tennis elbow.

The results will be presented on Thursday, March 21, 2013, at 5 pm, McCormick Place, Room N427 at the annual meeting of the American Academy of Orthopedic Surgeons (AAOS) in Chicago.

Tennis elbow, lateral epicondylar tendinopathy, is characterized by pain radiating from the outside of the elbow to the forearm and back of the hand when grasping or twisting. The pain associated with tennis elbow can be chronic and severe.

Researchers examined 230 patients with chronic tennis elbow. All had at least three months of symptoms and had failed conventional therapy. One hundred sixteen received treatment with PRP and 114 were in the control. All received .25 percent of the anesthetic bupivacaine with epinephrine, then the PRP group received one injection of PRP placed in the extensor tendon. Both groups were followed for up to 24 weeks. No differences were noted between the PRP and control groups prior to treatment.

PRP was prepared from venous whole blood via a desktop centrifuge and disposable canister at the point of care. The centrifuge separated the platelet-rich plasma, concentrated platelets and white blood cells, which were then injected at the site of the patient's injury. In theory, the growth factors that platelets secrete (not including human growth hormone) spur tissue recovery.

At 12 weeks, the PRP patients reported 55 percent improvement in their pain scores compared to 47 percent in the active control group. At 24 weeks, the PRP patients reported 71 percent improvement compared to 56 percent in the control group.

At 12 weeks, 37.4 percent of patients in the PRP group reported significant elbow tenderness versus 48 percent in the control group. At 24 weeks, the numbers again reflected this trend: 29 percent of PRP patients had significant tenderness versus 54 percent in the control. No significant complications occurred in either group.

The study showed the efficacy and level of results that can be obtained when using PRP as part of a treatment regimen. PRP is safe and results in improvements in pain scores and local tenderness compared to an active control group.

PRP significantly improves outcomes in tennis elbow patients

2013-03-21
CHICAGO – Eighty-four percent of patients suffering from chronic tennis elbow (lateral epicondylar tendinopathy) reported significantly less pain and elbow tenderness at six months following platelet rich plasma (PRP) treatment, according to results from the largest, multi-center study, to date, on PRP and tennis elbow, presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Tennis elbow is a common, painful condition affecting approximately 1 to 2 percent of the population. In this study, 230 patients suffering from chronic ...

Study outlines risk factors for poor outcome, mortality following hip fracture

2013-03-21
CHICAGO — A new study, presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), identifies predictors of complications and mortality following a hip fracture, including dialysis, cardiac disease, diabetes, and a longer time before surgery – the only modifiable risk factor when patients are hospitalized. Each year, more than 340,000 Americans are hospitalized for hip fractures. According to AAOS data, 69 percent of hip fracture patients are female and 46 percent are between the ages of 65 and 84. Many hip fracture patients suffer ...

Nurses provide care comparable to that of doctors for resolving health problems of low complexity

2013-03-21
A new study has found that Spanish nurses trained specifically to resolve acute health problems of low complexity provide care of comparable quality to that of general practitioners. Published early online in the Journal of Advanced Nursing, the findings suggest that nurses may be able to take on some of the care generally provided by physicians. Mireia Fàbregas, MD, of the Institut Català de la Salut, in Barcelona, Spain, and her colleagues randomized 1461 adult patients who requested same day appointments to see either nurses trained to respond to problems with low ...

Obesity alone may not affect knee replacement outcome or increase overall complication risk

2013-03-21
CHICAGO -- Obesity alone may not diminish outcomes or increase the risk of complications in total knee replacement (TKR) patients, according to two research studies presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). However, TKR replacement patients may face significantly longer hospital stays and related costs. Total knee replacement in obese patients previously has been associated with increased post-operative complications and lower clinical function scores in multiple research studies. In the study, "The Effect of ...

Knee implants designed specifically for female patients may not improve outcomes

2013-03-21
CHICAGO – Anatomic differences between male and female knees have resulted in the creation and regular use of gender-specific implants. However, a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) finds that a specialized prosthesis may not improve overall outcomes in female total knee replacement (TKR) patients. Female implants are narrower, with an atypical angle and a thinner anterior flange (front rim), reflecting the unique characteristics of the female knee. These knee components are used frequently in TKR ...

98 percent of total knee replacement patients return to life, work following surgery

2013-03-21
CHICAGO — Ninety-eight percent of total knee replacement (TKR) patients who were working before surgery returned to work after surgery, and of those patients, 89 percent returned to their previous position, according to new research presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Another related study highlights the life-restoring outcomes of total hip replacement (THR). Total knee replacement, or arthroplasty, among the most widely performed procedures in the world, is known to successfully relieve pain and restore ...

Moffitt Cancer Center researchers study use of dasatinib for patients with high-risk MDS

2013-03-21
Researchers at Moffitt Cancer Center have completed a phase II clinical trial to determine the safety and efficacy of dasatinib for patients with higher-risk myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia, or acute myeloid leukemia resulting from MDS and have failed treatment with azanucleosides. The therapy may not be effective for all patients, but those with trisomy 8 chromosomal disorder have higher rates of stable disease and respond better to treatment with dasatinib, the study shows. Results of this study appear in the March issue of Leukemia ...

Docking technique to repair torn elbow ligament yields favorable results in teen baseball players

2013-03-21
A study at Hospital for Special Surgery (HSS) found that a surgical procedure known as the "docking technique" to repair a torn elbow ligament in teenage athletes yielded favorable results. The outcomes were better than those in previously published reports on reconstruction of the ulnar collateral ligament (UCL), also known as Tommy John surgery, in this age group and may be attributed to technique-specific factors, according to the study authors. The paper, titled, "The Docking Technique for Elbow Ulnar Collateral Ligament Insufficiency: Two-Year Follow Up in Adolescent ...

Genes may be reason some kids are picky about food

2013-03-21
Parents may plead, cajole or entice their children to try new foods, but some kids just won't budge. Now, new research from the University of North Carolina at Chapel Hill reveals that the reason these kids fear new foods has less to do with what's on their plate and more to do with their genes. The work, led by Myles Faith, an associate professor of nutrition at UNC's Gillings School of Global Public Health, adds to the growing body of knowledge that genes play a significant role in children's eating behavior, including the tendency to avoid new foods. "In some respects, ...
