Mark Clatworthy, Steffen Sauer, Tim Roberts
PURPOSE: It is proposed that central femoral ACL graft placement better controls rotational stability. This study evaluates the consequence of changing the femoral tunnel position from the AM position drilled transtibially to the central position drilled transportally. The difference in ACL graft failure is reported. METHODS: This prospective consecutive patient single surgeon study compares the revision rates of 1016 transtibial hamstring ACL reconstructions followed for 6-15 years with 464 transportal hamstring ACL reconstructions followed for 2-6 years...

PURPOSE: Surgeons mainly consider the anterior anatomy of the distal femur in the treatment of patellar instability (PI) with trochlear dysplasia (TD). Through this research, the idea was to analyse the posterior femoral condyle length in TD. The research team posited the presence of morphological differences in the posterior part of the femoral epiphysis in TD compared to a control group. They also postulated that the posterior bicondylar angle (PCA), in the axial plane, was increased in TD...

PURPOSE: The mechanical axis of the lower limb has shown to vary between different weight-bearing conditions and change after total knee arthroplasty (TKA). The purpose of this study was to investigate the correlation between mechanical axis alignment in standing long-leg radiographs and limb loading after TKA. METHODS: Mechanical axis of the lower limb and limb loading have been prospectively evaluated in 115 patients 10 days and 3 months after TKA. By the moment of standing long-leg radiography for analysis of the mechanical leg axis, two digital scales separately captured the load of each limb...

PURPOSE: The purpose of this study was to clarify radiographic and clinical outcomes, as well as their association, of ankle sprain in children. METHODS: Patients who sustained a first-time ankle sprain were prospectively surveyed. Patients underwent radiography of the ankle in the mortise, lateral, anterior talofibular ligament (ATFL), and calcaneofibular ligament views at the first clinic visit to assess avulsion fractures of the distal fibula. Patients with avulsion fractures underwent radiography after 8 weeks to assess bone union...

PURPOSE: Traumatic high-grade acromioclavicular joint (ACJ) separations can be surgically stabilized by numerous anatomic and non-anatomic procedures. The return to sport (Maffe et al. in Am J Sports Med 23:93-98, 1995] and remaining sport-associated impairments after acute ACJ stabilization has not yet been investigated. METHODS: 73 consecutive athletes with acute high-grade ACJ separation were prospectively assigned into two groups (64.4% randomized, 35.6% intention-to-treat): open clavicular hook plate (cHP) implantation (GI) or arthroscopically assisted double double-suture-button (dDSB) implantation (GII)...

PURPOSE: Posterior-stabilized (PS)-total knee arthroplasty (TKA) can be applied in any of several variations in terms of the tibiofemoral conformity and post-cam mechanism. However, previous studies have not evaluated the effect of the condylar surface radii (tibiofemoral conformity) on wear in a customized PS-TKA. The present study involved evaluating the wear performance with respect to three different conformities of the tibiofemoral articular surface in a customized PS-TKA by means of a computational simulation...
