Researchers from Denmark have uncovered a potential link between oral contraceptive use and instances of ACL injuries that required surgical intervention in women. The researchers evaluated 4,497 women who were treated operatively for an ACL injury between July 2005 and December 2011 and 8,858 age-matched, uninjured controls.
After a knee replacement, there's no place like home for your physical therapy - or at least home may be just as good a place as a clinic to do your exercises. In a new study, knee replacement patients who followed a six-week, monitored exercise program at home showed similar progress to those who were in regular outpatient rehabilitation programs.
Every year, 330-thousand Americans undergo surgery to replace hip joints that have been damaged by age or overuse. After surgery most patients can go back to their normal activities but no running, no jumping and no high impact sports for some people who have been very physically active. Now, new research shows hip resurfacing may be the better option to get them back on their feet.
Use of platelet-rich plasma had no evident effect on patients undergoing total knee arthroplasty, according to study results. Researchers randomly assigned 40 patients who were scheduled to undergo primary unilateral total knee arthroplasty (TKA) to be treated with platelet-rich plasma (PRP) or to a control group. Patients' hemoglobin (Hb) and hematocrit levels were documented before surgery and again on days 1, 7, 14 and 28 postoperatively, and estimated blood loss was calculated. The researchers also recorded and assessed the patients' C-reactive protein (CRP) levels, range of motion, pain levels, knee extension muscle strength, knee swelling, circumference differences, Knee Society Knee Score, Knee Society Functional Score and KOOS at various time points throughout the study.
EOS imaging obtains FDA approval for hipEOS, the first 3D stereoradiographic planning software for hip arthroplasty
EOS imaging, the pioneer in orthopaedic 2D/3D imaging, announced today that the U.S. Food and Drug Administration has approved hipEOS, a 3D hip arthroplasty planning software based on EOS stereo-radiographic 2D/3D imaging. hipEOS is the first offering of a software portfolio associated with the EOS imaging system. Developed by OneFit medical, an EOS imaging group company, the software enables surgeons to perform, using EOS unique stereo-radiographic 2D/3D low dose images, pre-surgical planning including hip implant selection and virtual positioning in functional, weight-bearing 3D. The software takes full advantage of the bias-free, real size 3D patient anatomical information obtained from the EOS exam to help physicians define implant size and visualize pre-operatively the restoration expected from a total hip arthroplasty prior to surgery. hipEOS received a CE Mark in March 2014.
EOS Imaging recently announced the FDA has approved hipEOS, the company's new 3-D planning software for total hip arthroplasty procedures. Designed with the intent to improve preoperative planning, hipEOS allows surgeons to test everything from hip implant selection to positioning in functional, weight-bearing 3-D based on the anatomical data specific to each patient. These data stem from the company's stereo-radiographic 2-D/3-D imaging and represent the first instance of a software portfolio offered with the EOS imaging system, according to a company press release. This improvement in planning via hipEOS is believed to aid surgeons in the accuracy of the restoration they anticipate following THA.
DALLAS — During their minimum 2-year follow-up, researchers here reported a 1.9% rate of subsequent dislocation after total hip arthroplasty in a contemporary practice and noted 58% of these cases had an acetabular socket position within the Lewinnek safe zone.
“Most contemporary total hip arthroplasties that dislocate are within the Lewinnek safe zone,” Matthew P. Abdel, MD, said during his presentation at the American Association of Hip and Knee Surgeons Annual Meeting. “Cup position for some patients certainly lies outside this safe zone. Most importantly, new technologies will need better targets to hit prior to them being clinically relevant or economically feasible.”
Patients who underwent early total hip arthroplasty experienced better 10-year cup and stem survival compared with patients who underwent late total hip arthroplasty, according to study results.
Researchers searched the Medline databases from January 1990 to January 2014 and retrieved 19 articles reporting on the management of posttraumatic arthritis of the hip following acetabular fractures with the use of late total hip arthroplasty (THA), as well as articles where acetabular fractures were treated with early THA. In all, the researchers assessed THA outcomes following acetabular fracture in 654 patients.
With the number of total knee and hip replacements on the rise, doctors are looking for ways to reduce the amount of care needed after surgery. Prehabilitation (physical therapy before surgery) could help patients recover faster and save money.
Rehabilitation following knee or hip replacement is the standard of care. The physical therapy is designed to help patients adjust to new joints and strengthen muscles.
A new study found that physical therapy before the joint replacement surgeries reduced the need for rehab after the surgery.
Among patients who underwent total knee arthroplasty, intra-articular tranexamic acid significantly reduced total blood loss, drainage, reduction of hemoglobin and the need for transfusion without increasing the incidence of deep venous thrombosis and pulmonary embolism, making it safe and efficacious, according to study results.
Through a search of various databases for relevant randomized, controlled trials, researchers included seven studies comprising 622 patients. The researchers calculated mean difference in total blood loss, risk ratio for transfusion and complication rate in the tranexamic acid-treated group vs. the placebo group.
