🦵Valgus knees specifically benefit from JLO neutralisation following TKA.

❓Universal alignment strategies (kinematic/mechanical alignment) appear to be overly simplistic.

🎯 CPAK-specific alignment targets should be explored.

Another great South East Scotland Orthopaedic Research & Training day. Excellent talks, particularly from the legendary Prof John Keating. Endless wisdom and brilliant quotes from the past 😂

[John Bayram @jackbayram]

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?

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.

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

[John Bayram @jackbayram]

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 https://t.co/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 Bone & Joint Journal @BoneJointJ]

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.

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. https://t.co/dNqh6QjnQn

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.

[John Bayram @jackbayram]

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 Bone & Joint Journal @BoneJointJ]

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.

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.

[John Bayram @jackbayram]

Is the resistance of some surgeons to adopt UKA because our PROMs are not adequate for comparing TKA to newer techniques (UKA, robotic-assistance)?

"It is clear that there are considerable challenges facing healthcare provision. Knee osteoarthritis incidence is projected to increase between 75% to over 100% in the next three decades relative to current levels".

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.

[John Bayram @jackbayram]

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.

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 💪🧠🎯

[John Bayram @jackbayram]

"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.

[Bone & Joint Open @BoneJointOpen]

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%).
