Most PROMs following TKA have substantial ceiling effects. Even the FJS! How can we improve knee arthroplasty outcomes if patients are already hitting the ceiling using current measures? In press @JArthroplasty t.ly/oWy2l

Worse TKA outcomes in women are explained by difference in baseline characteristics and preoperative function. Earlier referral and preoperative optimisation may help reduce outcome disparities. In press @JArthroplasty t.ly/tBcoa

Dallas, it's been a blast. Great to hear what's happening at the cutting edge of hip and knee research. Hopefully i'll be back soon! #AAHKS2025

Fantastic insights and discussion around the pressing research questions of arthroplasty today at the 1st Edinburgh Arthroplasty Day @EdinOrthopaedic. Particularly great work into the future of outcome measurement for knees! @EdinburghKnee @ChetanKhatri2 pic.twitter.com/SCfzXOZXjQ

Honoured to receive the Kamal Deep Memorial Shield at the Annual Golden Jubilee Orthopaedic Research Showcase today! Thanks to @ChrisGeeOrtho & Fahd Mahmood for a fantastic event, and to Fred Picard for his moving tribute to Kamal.

The prosthetic joint’s alignment and its relationship to native mechanical axes remain an area of great interest as we seek to improve outcomes following TKA. #TKA #TotalKneeArthroplasty #JointReplacement ow.ly/XGkv50WiUJ4

Vonn eyes Olympics 2026. The comeback continues: US skier Lindsey Vonn targets the Milan-Cortina Olympics in February 2026 after returning to elite sport following partial knee replacement. espn.com/olympics/story…

Excellent South East Scotland Orthopaedics Research and Teaching day this year. Congrats @JoeEslandOrtho on putting together a great day. Special thanks prof @ahrwsimpson for some rollicking stories of the old days and wise words for the future.

Brilliant sessions at #BASK2025 on indications for partial knee arthroplasty @nicklondonknee & the biomechanical superiority of PKA @DrAmyGarner. Although evident, are the benefits of PKA over TKA fully captured by our current PROMs? or are ceiling effects in the way?🤔

The use of PROMs to assess the outcome after TKA and THA is increasing, with associated regulatory mandates. However, the robustness and clinical relevance of long-term data are often questionable. #TKA #THA #Arthroplasty ow.ly/PiJE50V8o8i

Can you ski after a partial knee replacement? Well, the US’ Lindsey Vonn just had a top-10 finish in the World Cup downhill after hers. sportskeeda.com/us/olympics/ne…

Is the resistance of some surgeons to adopt UKA because our PROMs are not adequate for comparing TKA to newer techniques (UKA, robotic-assistance)? "Are Current PROMs Fit for Purpose to Evaluate Unicompartmental Knee Arthroplasty?" Read open-access here: t.ly/wJ4lz

An important study that was ahead of its time. This confirms that robotic arm-assisted unicompartmental arthroplasty is here to stay, a timely paper in view of the NICE deliberation in the UK. #BJJ #Knee #Surgery #Robotics boneandjoint.org.uk/Article/10.130…

Traditional PROMs are unlikely to fully capture the benefits of UKA. Future studies should aim to define UKA and TKA populations, identify patient factors that predict UKA success, and validate high-performance PROMs for UKA. Published @JCM_MDPI t.ly/wJ4lz

Great fun teaching the @NHS_Education and @SESOrtho junior registrars how to set up a theatre today. Highlight for me was the high performance psychology session by @ArthurCalum 💪🧠🎯

"Vitamin D deficiency in hip fracture patients is associated with an increased mortality risk" @EJOST_ Vitamin D deficiency is linked to many chronic diseases, but supplementation may mitigate the associated mortality risk via falls/fracture prevention. t.ly/WsKVm

THA & TKA patients showed comparable eligibility (34%) with similar day-case success rates (59% to 61%), whereas medial unicompartmental knee arthroplasty patients demonstrated higher eligibility (52%) & day-case success (72%). #BJO #Arthroplasty #Ortho ow.ly/XoKV50Ufe8W

By current standards, the MCIDs for most joint-specific outcome measures would probably result in the conclusion that there was no clinically meaningful difference for a TKA or THA – an illogical conclusion. #BJJ #OrthoTwitter #Research @bjjeditor ow.ly/zjZy50TAcYy

Waiting for surgery is not benign, and those waiting more than six months had a clinically significant deterioration in their health-related quality of life and increased level of frailty. #BJJ #Patients @jackbayram @katiephughes @AndyBallantyne5 ow.ly/QR6n50SRrjB
