Thresholds for the Knee Injury and Osteoarthritis Outcome Score After TKA
Using data from a multicenter study spanning six countries on four continents, Mass General researchers are the first to propose patient-acceptable symptom state cut-points for use of the Knee Injury and Osteoarthritis Outcome Score after total knee arthroplasty.

Predicting Which Patients Are Unlikely to Improve After THA
Women, patients with high joint space width and those with poor scores on the Short-Form 36 Mental Component Summary are at increased risk of failing to achieve meaningful improvements in pain and/or function after total hip arthroplasty.

Benchmark Values Facilitate Evaluation of Patient-Reported Recovery After TKA
Orthopedic surgeons at Massachusetts General Hospital have established cutoff values for patient-reported outcome measures that can be used as benchmarks to assess recovery progress after total knee arthroplasty.

Vitamin E–diffused Crosslinked Polyethylene Liners Perform Well in Total Hip Arthroplasty
In a prospective study at Massachusetts General Hospital and three other centers, vitamin E–diffused, highly crosslinked polyethylene liners showed significantly less wear than mechanically annealed ultrahigh-molecular-weight polyethylene liners five years after total hip arthroplasty.

5-Year Results with Porous Titanium-Coated Acetabular Shell Poorer Than Those of Plasma-Sprayed Shell
In the first long-term study of its type, Massachusetts General Hospital researchers found an increased risk of radiolucency and pain with a porous titanium-coated acetabular shell compared with a proven plasma-sprayed shell.

Outcomes of Metal-on-Metal THA Poorer with Modular Stems
Many failures of metal-on-metal total hip arthroplasty are due to adverse local tissue reactions, which are associated with elevated metal ion levels due to implant wear. Mass General surgeons wondered whether the modular S-ROM stem, which has an additional metal-on-metal interface, influences outcomes.

Novel Drug-eluting Polymer May Improve Treatment of Prosthetic Joint Infection
The standard treatment for prosthetic joint infection requires patients to endure two surgeries beyond the original procedure, plus periods of inactivity. A new drug-eluting polymer developed at Mass General might change all that.
Biography
Dr. Malchau is a visiting professor of orthopedic surgery, joint arthroplasty, as well as a staff surgeon at Massachusetts General Hospital.
