Use of Floseal Hemostatic Matrix in total knee arthroplasty safely provided improved control of blood loss and reduced the predicted probability of postoperative blood transfusion, according to study results.
Although obese patients undergoing hip arthroscopy started with lower absolute scores preoperatively and ended with lower overall absolute postoperative scores, they showed substantial benefit from surgery, demonstrating a degree of improvement similar to non-obese patients, according to study results.
In patients with severe varus deformity of the knee, mini-midvastus total knee arthroplasty had no adverse clinical outcomes as a result of poor implant position, according to study results.
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.
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 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.
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.
Recently published study data indicated short-stem and straight-stem implants for total hip arthroplasty exhibited no significant differences in functional outcome measures.
Researchers conducted a randomized, double-blinded study of 80 patients who underwent total hip arthroplasty (THA). Patients were grouped by whether their THA utilized a short-stem or conventional straight-stem implant. Radiological and functional outcomes were evaluated at 6 weeks postoperatively, and quality of life was quantified via Harris Hip Score, SF-36 and WOMAC scores.
No significant changes in offset differences were observed in either group from before surgery to after surgery. At final follow-up, no significant differences between groups were found in Harris Hip Score, SF-36 or WOMAC values, according to the researchers.
Comparison of long-term survival rates among both cohorts will help determine whether short stems are a viable alternative THA solution, the researchers concluded.
