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.

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 ...

Sagittal femoral morphology is not associated with robotic planning or soft‐tissue balance during robotic‐assisted total knee arthroplasty: An analysis from the Brescia Knee Research Group

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate the influence of sagittal femoral morphology on robotic planning parameters and intraoperative soft‐tissue balance in robotic‐assisted total knee arthroplasty (TKA). It was hypothesised that sagittal femoral morphology has limited impact on intraoperative planning and laxity.

Coronal alignment behaviour across the knee range of motion is associated with constitutional alignment and soft‐tissue balance: The REAL HKA classification

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate intraoperative, pre‐resection coronal alignment throughout the range of motion (ROM) in knees undergoing robotic‐assisted total knee arthroplasty (ra‐TKA), and to assess its relationship with the Coronal Plane Alignment of the Knee (CPAK) and the Robotic Evaluation of Articular Laxity (REAL) classifications.

Femoral component internal rotation in functionally aligned robotic‐assisted total knee arthroplasty does not impair functional outcomes

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Femoral component internal rotation tightens the medial flexion gap and medialises femoral trochlea position, thus influencing patellofemoral tracking and function. Therefore, one of the tenets of mechanically aligned total knee arthroplasty (TKA) has been to avoid femoral component internal rotation relative to the transepicondylar ...

Patients with obesity have a higher risk of periprosthetic joint infection and more frequent polymicrobial infections after knee arthroplasty: A nationwide register‐based study from Denmark

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare the 2‐year incidence of (1) revision due to periprosthetic joint infection (PJI) and (2) all‐cause revision after primary knee arthroplasty (KA) in patients with/without obesity and to compare the microbial profiles in early (≤ 90 days) and late (91–730 days) PJI.

Previous bariatric surgery was not associated with an increased risk of reintervention within 2 years after knee arthroplasty: A nationwide register‐based study from Denmark

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Obesity is a major risk factor for knee osteoarthritis (KOA). Bariatric surgery (BAS) effectively induces weight loss, but some of these patients subsequently require knee arthroplasty (KA) despite substantial weight reduction. However, the impact of prior BAS on the risk of reintervention, antibiotic use and mortality following KA ...

Posterior tibial slope is linearly related to anteroposterior shift of the tibiofemoral contact mechanics: A biomechanical study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the changes in tibiofemoral contact mechanics following an infra‐tubercle slope‐modifying osteotomy. Methods An infra‐tubercle slope‐modifying osteotomy was performed on eight fresh‐frozen cadaveric knees and fixed with an external fixator, which allowed for accurate slope adjustments from 15° to 0° in 5° increments.
