Prior anterior cruciate ligament reconstruction: Comparable outcomes but reduced knee flexion after robotic functionally aligned total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Total knee arthroplasty (TKA) after anterior cruciate ligament reconstruction (ACLR) is technically demanding and has been associated with higher complication rates. This study aimed to evaluate whether patients with prior ACLR undergoing image‐based robotic‐assisted TKA performed under functional alignment (FA) principles achieve ...

Increased radiolucency on conventional radiographs around tibial components does not imply more load‐induced displacement of a total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose After total knee arthroplasty (TKA), radiolucent lines on routine conventional radiographs are commonly interpreted as impaired tibial component fixation, although their relation to implant motion remains unclear. This necessitates a comparison with measured component displacement.

Operative Time Learning Curve for an Image-Free Robotic Arm Assisted Total Knee Arthroplasty: A Cumulative Sum Analysis

Arthroplasty Today
Background: Robotic arm assisted total knee arthroplasty (RA-TKA) aims to improve accuracy in bone resection, implant positioning, and joint alignment compared to manual TKA (M-TKA).

Unicompartmental knee arthroplasty is associated with greater patient preference but higher revision rates than total knee arthroplasty in the same patient: A systematic review and meta‐analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Despite the high prevalence of isolated knee compartment disease, unicompartmental knee arthroplasty (UKA) is often avoided in patients with a contralateral total knee arthroplasty (TKA). The present study aimed to evaluate the impact of a contralateral TKA on functional outcomes, patient preference and long‐term survivorship following

Intraoperative variability between the anteroposterior and posterior condylar axes in primary TKA supports a 20° proximal trochlear entrance design for unrestricted kinematic alignment

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Unrestricted kinematic alignment (uKA) in total knee arthroplasty (TKA) creates a challenge for trochlear design. Femoral implants designed for mechanical alignment (MA) use asymmetrical posterior bone cuts to adjust axial rotation and optimize patellofemoral tracking. In uKA, posterior bone cuts are calipered resections.

No clinical and functional benefit after medial congruent compared to ultra congruent total knee arthroplasty at 1 year: A prospective randomized controlled study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Various conforming bearing designs are used during total knee arthroplasty (TKA), yet their impact on clinical outcomes remains uncertain. In recent years, the use of medial congruent (MC) and ultra congruent (UC) onlays has gained popularity.

Short-Term Outcome after Computer-Assisted versus Conventional Total Knee Arthroplasty: A Randomised Controlled Trial

Journal of Orthopaedic Surgery, 2015
Purpose. To compare the short-term functional outcome after computer-assisted total knee arthroplasty (TKA) versus conventional TKA. Methods. 23 men and 67 women aged 48 to 80 years were randomised to undergo (1) conventional TKA using an intramedullary ...

Tibia‐first, gap‐balanced patient‐specific alignment in total knee arthroplasty achieves better ligament balance than mechanical, kinematic and functional alignment strategies

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study evaluates four different alignment techniques to assess total knee arthroplasty (TKA) balance. Methods A prospective cohort of 400 patients undergoing primary robotic‐assisted cruciate‐retaining TKA was analysed. The Velys TKA robotic system collects a balance curve that enables the surgeon to intraoperatively analyse the ...

Kinematic Alignment in TKA Using the Contralateral Healthy Knee as Reference: A Combined Finite Element and Clinical Analysis. [PDF]

Orthop Surg
In patients with unilateral knee osteoarthritis, a novel natural kinematic alignment (NKA) using the contralateral healthy knee as reference was compared with mechanical alignment (MA) and kinematic alignment (KA) via finite element analysis and a clinical study. NKA provided more balanced stress in neutral/mild varus models.
