Secondary analysis of randomized trial finds robotic-assisted THA with CoC bearings reduces incidence and severity of implant noise. |
 |
|
Ceramic-on-ceramic (CoC) bearings in THA have a host of benefits, but are not without its issues. Noise generation in particular has been a major concern, with reported incidence rates as high as 30%. Given the role of inaccuracy in implant placement on noise generation, its possible that robotic-assisted THA, which has greater placement accuracy, could reduce noise complaints.
74 patients who received either a robotic-assisted or conventional THA using a CoC bearing were included in this secondary analysis of an RCT. Outcomes of interest primarily focused on noise generation, such as predictors of noise complaints.
-
The rate of noise complaints was substantially higher in the conventional THA group compared to the robotic THA group (5.4% vs. 32.4%, p=0.008). Conventional THA was a significant predictor of noise complaints (OR 7.10, p=0.013) in the logistic regression analysis.
-
Implant placement was significantly more accurate with robotic THA across several parameters.

|
|
|
Bottom Line: Robotic-assisted arthroplasty with CoC bearings is likely to reduce noise complaints through more precise component placement. |

CBT physical therapy found to be ineffective in treating traumatic lower extremity injury |
 |
|
Traumatic lower extremity injuries can negatively affect quality of life for years. Targeting negative pain beliefs and behaviours through interventions like cognitive behavioural therapy (CBT) has been found to be effective among physical therapists, but its efficacy is not well known among post-traumatic patients.
325 patients with an acute lower extremity injury were randomized to receive either a telephone-based CBT physical therapy program or an education program after hospital discharge. The primary outcome was patient-reported physical function, with pain, health status, and other physical function tests being secondary outcomes.
-
Unexpectedly, CBT physical therapy provided no benefit over conventional education group in patient-reported function.
-
Similarly, no differences in pain, quality of life, or objective physical function measures were observed.
|
|
|
|
Bottom Line: Contrary to research in other areas, CBT-based physical therapy provided no benefit over conventional education for improving patient outcomes in a lower-extremity traumatic injury population. |
