Arthroplasty News and Research RSS Feed - Arthroplasty News and Research

Arthroplasty is a orthopaedic surgery procedure, in which the arthritic or dysfunctional joint surface is replaced with something better or by remodeling or realigning the joint by osteotomy or some other procedure. Previously, a popular form of arthroplasty was interpositional arthroplasty with interposition of some other tissue like skin, muscle or tendon to keep inflammatory surfaces apart or excisional arthroplasty in which the joint surface and bone was removed leaving scar tissue to fill in the gap. Other forms of arthroplasty include resection(al) arthroplasty, resurfacing arthroplasty, mold arthroplasty, cup arthroplasty, silicone replacement arthroplasty, etc. Osteotomy to restore or modify joint congruity is also an arthroplasty.
ACB could lead to quicker, safer recovery after total knee arthroplasty

ACB could lead to quicker, safer recovery after total knee arthroplasty

Two commonly used nerve blocks during total knee arthroplasty (TKA) are the adductor canal block (ACB) and femoral nerve block (FNB). ACB appears to preserve quadriceps strength superior to FNB while maintaining adequate postoperative pain control. Improving early functional outcome could lead to a quicker and safer recovery with earlier hospital discharges. [More]

HSS study examines cost-effectiveness of knee replacement surgery in high- and low-volume hospitals

HSS study examines cost-effectiveness of knee replacement surgery in high- and low-volume hospitals

If all patients scheduled for knee replacement were directed to high-volume hospitals for the surgery, it could save the U.S. healthcare system between $2.5 and $4 billion annually by the year 2030, according to a study at Hospital for Special Surgery in New York City. [More]

High-resolution X-ray method can predict risk of re-operation in patients who receive new hip prosthesis

High-resolution X-ray method can predict risk of re-operation in patients who receive new hip prosthesis

Between 5 and 30 percent of those who receive a new hip prosthesis will require a re-operation during their lifetime. New research shows that a high-resolution X-ray method can predict which patients have the greatest risk of re-operation. [More]

Study: Knee or hip replacement surgery may increase heart attack risk

Contrary to recent reports, Boston-based researchers found that osteoarthritis patients who had total knee or hip joint replacement surgery, known as arthroplasty, were at increased risk of heart attack (myocardial infarction) in the early post-operative period. [More]

Arthrosurface inlay implant dramatically reduces progression of osteoarthritis

A recent study by Feucht et al, published in the KSSTA Knee Journal, compared the Arthrosurface HemiCAP Wave implant, which is based on an "inlay" Arthroplasty design, versus an "onlay" design implant for isolated patellofemoral disease. While both implant groups showed similar improvements in function and pain scores, none of the patients in the "inlay" group showed progression of osteoarthritis (OA). [More]
