A relevant number of patients do not increase their engagement in physical, social and leisure activities at the medium-term after total knee arthroplasty: a prospective cohort study.

Purpose: The purpose of this study was to investigate the changes in engagement in physical, leisure and social activities in older adults following primary TKA.

Methods: A prospective study of 106 patients with a mean age of 72.6 (SD 7.

Similar outcomes of constrained condylar knee and rotating hinge prosthesis in revision surgery for extension instability after primary total knee arthroplasty.

Background: Instability is one of the most common reasons for total knee arthroplasty (TKA) failure. Constrained prosthesis can be used for significant ligamentous laxity, but there is not much evidence on the appropriate level of restriction for unstable varus-valgus TKA. The objective of this study was to compare the outcome and survival at a minimum follow-up of five years between rotating hinge knee prosthesis (RHK) and constrained condylar knee prosthesis (CCK) for extension instability following primary TKA.

Varus alignment of the tibial component up to seven degrees is not associated with poor long-term outcomes in a neutrally aligned total knee arthroplasty.

Purpose: The purpose of this retrospective study was to evaluate the effect of varus alignment of the tibial component on the outcomes with a minimum follow-up of 10 years. The hypothesis was that varus alignment of the tibial component might not affect the outcomes and survival of a neutrally aligned primary TKA.

Methods: A matched case-control study was designed between 66 patients with varus alignment of the tibial component and 66 with neutral alignment with a minimum follow-up of 10 years.

V-Y turndown flap augmentation for acute quadriceps rupture after total knee arthroplasty: a prospective matched cohort study.

Purpose: To evaluate the effectiveness of the quadriceps V-Y turndown augmentation for acute quadriceps tendon ruptures in the setting of TKA.

Methods: Prospective cohort of 22 patients with quadriceps rupture after TKA were compared with 44 matched patients underwent TKA without quadriceps rupture. Quadriceps ruptures were treated within three weeks after injury by suture augmented with Scuderi quadriceps V-Y turndown flap.

Similar outcomes and satisfaction after transtibial versus transportal femoral drilling for anterior cruciate ligament reconstruction in young adult recreational athletes.

Purpose: Controversy continues regarding whether the transtibial (TT) and transportal (TP) methods for anterior cruciate ligament (ACL) reconstruction provide similar or different outcomes, and the evidence on patient satisfaction is very limited. The objective of this study was to compare functional outcomes and patient satisfaction in young adult recreational athletes who underwent arthroscopic hamstring ACL reconstruction using either the TT or the TP femoral tunnel drilling method.

Methods: A nonrandomized prospective study was designed to compare the outcomes of arthroscopic hamstring ACL reconstruction using TT or TP method.
