The Pulse

Vol. 4 · Issue 19 · 14 May 2026


Good Morning.

The goal of orthopaedic research -- and OrthoEvidence -- is to use the latest evidence to change practice.


In this week's edition of The Pulse, we highlight two recent practice-changing RCTs: one in arthroplasty, the other in ankle fracture management.

In today's edition:

•  Should we be operating on unstable lateral malleolus fractures?

•  To cement or not to cement: TKA with patellar resurfacing

•  Chatting with a former chief

Should we be operating on unstable lateral malleolus fractures?

SUPER-FIN Trial in the BMJ finds no advantage of surgery over cast immobilization, challenging conventional practice. 

For patients with isolated Weber B ankle fractures, surgery has always been the natural course of action. But is it truly necessary?


The SUPER-FIN Trial, a non-inferiority RCT published in the BMJ and including over 126 patients, aimed to compare cast immobilization with surgical fixation to see whether operating room resources can be saved, and conventional practice can be changed.


The results? No difference in function, pain, quality of life, or radiographic outcomes. Parity on all fronts. And more treatment-related harms in the surgery group.


It's a study that could change the way we treat patient and allocate scarce health-care and operating room resources.

Recent RCT finds no evidence of a need for cementing in TKA

Minimal differences between patients who received a cemented or fully uncemented TKA with patellar resurfacing.

Cemented TKA has always been the standard, but does it really provide any advantage in clinical outcomes?


According to a recent 5-year study by Dr. Simon Young and colleagues, presented at the AAOS 2026 meeting, there might not be much of a difference.


Among 316 patients randomized to receive a cemented or fully uncemented implant with patellar resurfacing, no differences in patient-reported outcome measures, minor wound complications or manipulation under anesthesia.


Only a small difference in surgical time, and a greater incidence of non-progressive radiolucent lines in the uncemented group which is likely not clinically relevant.

Chatting with former JBJS chief Jim Heckman

In the latest instalment of the OrthoJoe interview series with JBJS editors, Dr. Mohit Bhandari and Marc Swointkowski sit down with Dr. James Heckman, who piloted the JBJS journal through a host of transformations through the first decade of the 2000s.


If you're interested in the evolution of JBJS, including the business challenges that were faced and the important editorial changes that were made, this is the episode for you!
