Restoration of the trochlear peaks is unnecessary with a kinematic alignment‐optimized femoral component as under‐stuffing results in equivalent or better patient‐reported outcome scores

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Kinematic alignment (KA) total knee arthroplasty (TKA) aligns the femoral component to restore the pre‐arthritic posterior joint line, potentially altering the heights of the medial and lateral trochlear peaks. It remains unclear whether the femoral component should be adjusted to correct deviations in peak height.

Does mobile-bearing have better flexion and axial rotation than fixed-bearing in total knee arthroplasty? A randomised controlled study based on gait

Journal of Orthopaedic Translation, 2020
Objective: To analyse the 6 degrees of freedom of the knee and gait data of patients with medial knee osteoarthritis before and after fixed-bearing (FB) and mobile-bearing (MB) total knee arthroplasty (TKA) ​and examine the influence of TKA on gait ...

Are current total knee arthroplasty implants tested and approved for personalised alignment?

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Total knee arthroplasty (TKA) traditionally aims for neutral mechanical alignment (MA) to ensure implant longevity. However, this approach ignores individual knee variations, potentially leading to soft‐tissue imbalances and suboptimal functional outcomes. As an alternative, personalised alignment techniques (PAT) have emerged that aim

Patellofemoral alignment safe zones in robotic‐assisted TKA do not affect outcomes but do influence patellar resurfacing rates

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Anterior compartment management remains a challenging aspect of total knee arthroplasty (TKA), particularly in personalised alignment strategies. This study aimed to assess whether restoring patellofemoral alignment parameters within predefined safe zones—specifically patellar tilt (PTi), patellar translation (PTr) and patellar offset (

Bisphosphonate use in patients undergoing total knee arthroplasty reduces overall and aseptic revisions and periprosthetic bone mineral density loss: A systematic review from the FP‐UCBM Knee Study Group

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose Bisphosphonates (BPs), widely used for osteoporosis management, have garnered attention in the context of total knee arthroplasty (TKA) for their potential to preserve periprosthetic bone mineral density (BMD) and mitigate risks such as aseptic loosening, periprosthetic fractures, and implant failure. This study systematically reviewed
