Physical exam findings of patellofemoral grind may help predict which patients with knee osteoarthritis (OA) are likely to experience significant worsening of their disease, analysis of data from the Osteoarthritis Initiative showed.
Individuals with persistent patellofemoral grind had a greater annual loss of cartilage volume compared with those without this clinical finding (1.30% vs 0.90%, P<0.001), according to Yuanyuan Wang, MD, PhD, of Monash University in Melbourne, Australia, and colleagues.
They also had twice the risk of having a total knee replacement by 6 years (OR 2.10, 95% CI 1.30-3.38, P=0.002), the researchers reported online in Arthritis Care & Research.
The natural history of knee OA can vary notably among patients, and because of the increasing numbers of affected patients worldwide it has become critical to identify those who are most likely to progress, so as to better target healthcare resources.
Some complications are more common when total knee replacement surgery is done as an outpatient or same-day procedure, reports a study in the December 6, 2017 issue of TheJournal of Bone & Joint Surgery. The journal is published in partnership with Wolters Kluwer.
Compared to conventional inpatient surgery, patients undergoing outpatient total knee arthroplasty (TKA) experience higher rates of certain complications, including infections, repeat surgery, and blood clots, according to the new research by Armin Arshi, MD, of the David Geffen School of Medicine at UCLA and colleagues.
