Gait Analysis of Patients with a Rotating Hinge Knee Prosthesis after Revision Total Knee Arthroplasty [PDF]

Background: The number of revision total knee arthroplasty (TKA) procedures performed worldwide is increasing. The rotating hinge knee type (RHK) prosthesis is used for revision TKA.

Preoperative age, BMI and KL grade predict long‐term functional outcome of knee arthroplasty better than CPAK‐classification

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To assess whether coronal plane alignment of the knee (CPAK) is associated with functional outcome of total knee arthroplasty (TKA) and identify factors predicting functional outcomes during 10 years of follow‐up in a prospective cohort. Methods In total, 250 patients aged 65 or younger were enrolled.

Study on Gait Efficiency and Energy Cost of Below Knee Amputees After Therapeutic Practices [PDF]

, 2011
An earlier research advocated that a below knee amputee (BK) with conventional trans-tibial prosthesis attains higher gait efficiency at lower energy cost with therapeutic practices of proper time and co-ordination in compare to normal subjects of ...

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 ...

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

Experimental Study on an Active Knee Joint Mechanism without an External Energy Source [PDF]

, 2009
An above knee prosthesis that is used by femoral amputees has a knee joint mechanism as an alternative function of a knee. A Knee brace also has a knee joint mechanism for securing stability of a knee during the stance phase.

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.

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 ...
