Decreased rate of joint replacement for RA patients on biologics

A study published in the European League Against Rheumatism Annual Congress last month shows that the incidence of knee and hip replacement declined after the introduction of biologics to national rheumatoid arthritis (RA) treatment guidelines.

The study looked at 30,868 patients diagnosed with RA at the rheumatology department between 1996 and 2011 and compared them with 301,527 controls from the general population. The baseline total knee replacement (TKR) incidence rate per 1,000 person-years was 5.87 for RA versus 0.42 for the controlled group. Prior to 2002, the incidence of total knee replacement increased among RA patients, but started to decrease after the introduction of bDMARDs and their associated guidelines in 2003. In February of 2007, the rate of TKR changed to 1.8 TKRs/1,000 person. Over the study period, the incidence of total knee replacement and total hip replacement increased among the general population controlled group. In contrast, there was a downward trend among RA patients.

Lene Dreyer, MD, from the Center for Rheumatology and Spine Diseases in Denmark, is one of the author the study. Dreyer explained: “Our findings show a clear downward trend in these two operations in RA patients in Denmark since the additions of [biologic disease-modifying anti rheumatic drugs] bDMARDs to treatment protocols. Also, the overall pattern of our findings is in line with those recently reported from England and Wales.”

3D printer provides new hip joint and hope for 71-year-old woman

PrinterBritish surgeons implanted a first-of-its-kind hip joint made on a 3D printer on 71-year-old Meryl Richards. The implant is held together with the patient’s own stem cells. After the surgery, Richards was able to walk unassisted.

The implant is made from titanium metal and was tailor-made for Richards using precise measurements taken from detailed body scans. Before this operation, Richards had six other hip replacements that left her pelvis very weak – to the point where her leg had punched a hole through the bone. As a result, one leg was two inches shorter, causing immense pain and making her disabled and wheelchair bound.
