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.

Functional somatic syndromes are associated with inferior outcomes and increased complications after hip and knee arthroplasty: a systematic review

Arthroplasty
Background Functional somatic syndromes (FSSs), defined as chronic physical symptoms with no identifiable organic cause, may impact results after hip and knee arthroplasty.

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 ...

Uncompromised total knee arthroplasty function after distal femoral osteotomy: a self-matched study of bilateral total knee arthroplasties following unilateral osteotomy with a mean 32-year follow-up

Bone & Joint Open
Aims: Distal femoral osteotomies (DFOs) are commonly used for the correction of valgus deformities and lateral compartment osteoarthritis. However, the impact of a DFO on subsequent total knee arthroplasty (TKA) function remains a subject of debate ...

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.

Estimation of Blood Loss in Total Knee Arthroplasty with and without Tourniquet [PDF]

, 2009
Total knee arthroplasty (TKA) without a tourniquet can reduce the risk of large venous emboli, but is associated with increased blood loss. To provide an accurate estimate of this blood loss, we divided 136 patients who underwent primary TKA into four ...

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 ...
