Total Knee Arthroplasty

According to published results, intra-articular corticosteroid injection for manipulation under anesthesia during total knee arthroplasty improved range of motion without increasing risk of joint infection.

According to the published results, cementless fixation was associated with increased risk of aseptic loosening, revision and reoperation within 2 years after total knee arthroplasty.

DALLAS — For patients undergoing outpatient total hip or knee arthroplasty, hypobaric lidocaine significantly reduced time to discharge and physical therapy assessment compared with longer-acting spinal drugs or general anesthesia.

DALLAS — At the Orthopaedic Research Society Annual Meeting, Elizabeth H. Copp discussed kinematic differences between operated and contralateral knees after unicompartmental knee arthroplasty compared with total knee arthroplasty.

Results showed patients who underwent unicompartmental knee arthroplasty for medial compartment osteoarthritis had lower joint awareness, decreased pain, improved function and higher satisfaction compared with total knee arthroplasty.

KOLOA, Hawaii — Results showed use of Zynrelef as part of a multimodal analgesia protocol may significantly reduce pain and opioid use after total knee arthroplasty.

GRAPEVINE, Texas — Patients with a thin native patella who underwent patellar resurfacing during primary total knee arthroplasty had 98% survivorship free of patellar revision at median 10-year follow-up, according to a presenter.

Randomized controlled trials sit atop the research triangle as the best-quality evidence available in medical research. Using the best method to randomly assign patients in a trial is critical to account for sample size and multiple covariables.

KOLOA, Hawaii — Web-based follow-up care for routine total hip and knee arthroplasty may be cost-effective and safe, but requires some work for implementation, according to a presenter at Orthopedics Today Hawaii.

KOLOA, Hawaii — Patient activity after total joint arthroplasty can be highly variable and depends more on the patient than the surgery, according to a presenter here.
