Inferior Screw Placement Drastically Improves Revision THA Outcomes
Massachusetts General Hospital researchers have determined that inferior screw fixation drastically reduces failure after revision total hip arthroplasty.

Injection Drug Use Tied to Substantially Increased Risk of Periprosthetic Joint Infection
Hany Bedair, MD, Kyle Alpaugh, MD, Christopher Melnic, MD, and colleagues determined injection drug use is a significant risk factor for periprosthetic joint infection after total joint arthroplasty, finding in the largest study to date that the odds are increased more than nine-fold compared with a matched cohort.

Diagnosing Periprosthetic Joint Infection After Unicompartmental Knee Arthroplasty
Christopher Melnic, MD, Hany S. Bedair, MD, and colleagues derived optimal lab values for diagnosing periprosthetic joint infection after partial knee arthroplasty. They found they align more closely with international consensus than previously proposed thresholds for unicompartmental knee arthroplasty.

Race, Ethnicity & Income Predict Level of Disability at Time of Total Joint Replacement
Christopher M. Melnic, MD, Hany S. Bedair, MD, and colleagues looked at the correlation between race, ethnicity, income, and certain patient-reported outcome measures/scores for patients scheduled for primary total hip or total knee arthroplasty.
-
Mechanism of Knee Flexion Differs Between Morphological and Physiological Measurements
In a study with implications for developing total knee arthroplasty systems and planning patient-specific procedures, a bioengineering research team led by Guoan Li, PhD, and Hany Bedair, MD, compared methods for evaluating knee joint motion, and identified two separate mechanisms of axial rotation in the knee.
-
Shared Decision-Making Tied to Better Outcomes in Patients With Knee Osteoarthritis
When Massachusetts General Hospital researchers provided a decision aid to all patients with hip or knee osteoarthritis before they consulted a surgeon, 68% met criteria for well-informed, patient-centered (IPC) decisions about treatment, and patients with knee osteoarthritis who made IPC decisions had better outcomes.
-
Elevated BMI Is a Risk Factor for Failure to Achieve Minimal Clinically Important Difference After TKA
Researchers from the Center for Hip & Knee Replacement found that higher BMI increases the risk that a patient undergoing total knee arthroplasty will not notice meaningful improvement. The risk is particularly high for high-functioning patients who have relatively low preoperative pain.
-
HIV Positive Patients at Higher Risk of VTE After TJA
Jeffrey J. Olson, MD, and Hany S. Bedair, MD, of the Department of Orthopaedic Surgery, and colleagues found that the odds of venous thromboembolism after total hip or knee replacement were 11 times higher in HIV-positive patients than in matched HIV-negative controls.
-
No Factor Predicts Need for Ultracongruent Insert During TKA
Hany S. Bedair, MD, Christopher M. Melnic, MD, and Akhil Katakam, MBA, of the Department of Orthopaedics, and colleagues found no difference in pre- or postoperative measures between patients who underwent total knee arthroplasty using a cruciate-retaining component and those who received an ultracongruent component.
-
Risk of Dislocation in Patients After THA Higher in Spinal Fusion Than Ankylosing Spondylitis
After total hip arthroplasty, the risk of dislocation is higher in patients with a history of spinal fusion than in patients with ankylosing spondylitis, and increased lordosis of the lumbar spine seems to explain the discrepancy.
-
Algorithm to Identify Patients at Risk of Post-TKA Opioid Dependence
A machine learning algorithm shows promise for determining which patients are at increased risk of opioid dependence after total knee arthroplasty.
-
Opioid Use Is Similar After Patellofemoral Knee Arthroplasty and TKA
One month after patellofemoral knee arthroplasty, the percentage of patients using opioids for pain relief was about the same as after total knee arthroplasty and significantly higher than among patients who had medial unicompartmental knee arthroplasty.
-
Editorial: Periprosthetic Joint Infection Is a Disease Unto Itself
Periprosthetic joint infection is not a complication, a Massachusetts General Hospital orthopedic surgeon argues—adding that care should be provided by multidisciplinary specialty centers.
-
Successful Treatment of HCV Prior to TKA Improves Outcomes
In patients with hepatitis C infection who are treated prior to total knee arthroplasty, achieving a sustained virologic response significantly reduces the risk of postoperative complications, including prosthetic joint infection and the need for revision.
-
Wider Adoption of Customized Knee Implants Could Reduce Costs
The first systematic study of customized knee implants suggests that greater adoption could reduce costs for patients, hospitals and insurers, but better insurance coverage would be required.
-
Treatment for Chronic Hepatitis C Prior to Total Hip Arthroplasty Reduces Periprosthetic Joint Infection
In the first study to address the question, orthopedic surgeons at Massachusetts General Hospital demonstrated that patients with chronic hepatitis C infection should be treated prior to total hip arthroplasty to reduce the risk of surgical complications.
-
Lab Tests Predict Outcome of Two-Stage Exchange for Periprosthetic Joint Infection
Two-stage exchange arthroplasty is extremely costly and associated with high morbidity. Is it possible to identify patients at high-risk of failure?
-
Opioid Prescription Refills More Common after TKA Than THA
Total knee arthroplasty patients, particularly those with comorbidities, are more likely to refill opioid prescriptions than those receiving total hip arthroplasty.
-
Infection Care Costs after THA Greatly Exceed Expectations
Care costs to society calculated for periprosthetic joint infections after total hip arthroplasty are over three times prior cost estimates.
