Isokinetic performance and function are similar after total hip arthroplasty applied with a posterior or anterolateral approach: a randomised controlled trial.

Hip Int 2021 Apr 26:11207000211012989. Epub 2021 Apr 26.

Department of Orthopaedics and Traumatology, Gulhane Teaching and Research Hospital, Ankara, Turkey.

Background: There are ongoing debates on the effects of surgical approach on outcome after total hip arthroplasty (THA). It was hypothesised that with the anterolateral approach, trauma to the abductor arm can occur and related detrimental effects can diminish the postoperative outcomes. In this first randomised controlled trial in the literature on this subject, isokinetic performance and patient-reported functional outcomes were evaluated in patients undergoing THA with a posterior approach (PA) and an anterolateral approach (ALA).

The Single Leg Squat Test: A "Top-Down" or "Bottom-Up" Functional Performance Test?

Int J Sports Phys Ther 2021 Apr 1;16(2):360-370. Epub 2021 Apr 1.

Colorado Mesa University.

Background: Medial knee deviation (MKD) during the single leg squat test (SLST) is a common clinical finding that is often attributed to impairments of proximal muscular structures. Investigations into the relationship between MKD and the foot and ankle complex have provided conflicting results, which may impact clinicians' interpretation of the SLST.

Purpose: The purpose of this study was to compare ankle dorsiflexion range of motion (ROM) and foot posture in subjects that perform the SLST with MKD (fail) versus without MKD (pass). Read More
