Hop tests can result in higher limb symmetry index values than isokinetic strength and leg press tests in patients following ACL reconstruction
AbstractPurposeQuadriceps weakness is a common clinical sign following anterior cruciate ligament injury and reconstruction surgery (ACLR). The aim of this study was to compare strength deficits and the limb symmetry index (LSI) from three different types of functional tests: isokinetic dynamometry, hop test, and leg press.MethodsA total of 26 subjects with ACLR (average 8.3  months post-operation) participated in the study. The peak knee extension torque was tested with isokinetic dynamometry at 60/180/300 °/s (ISO60/180/300). Hop distance was tested during single hop (SH) and triple hop (TH). Unilateral pea...

Defining the three most responsive and specific CT measurements of ankle syndesmotic malreduction
ConclusionsThe most reliable method to assess the syndesmosis on CT was to compare side-to-side differences using three distinct measurements, one for each type of fibular malreduction, allowing assessment of the magnitude and directionality of syndesmosis malreduction. Reliable evaluation is essential for assessing subtle syndesmosis injuries, malreduction and surgical planning. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Arthroscopic matrix-associated, injectable autologous chondrocyte transplantation of the hip: significant improvement in patient-related outcome and good transplant quality in MRI assessment
ConclusionsInjectable MACT is a promising minimally invasive treatment option for full-thickness cartilage defects of the hip caused by FAI. A significant improvement in symptoms and function associated with an increase in quality of life was detected in patients treated with injectable MACT combined with FAI surgery.

ConclusionThe JLCA change could be larger in patients with large latent medial laxity or severe varus deformity requiring a large correction, which could lead to unexpected overcorrection in HTO. Postoperative JLCA change should be considered in preoperative surgical planning.

Bicruciate-stabilised total knee arthroplasty provides good functional stability during high-flexion weight-bearing activities
ConclusionAlthough weight-bearing resulted in a posterior location of the medial and lateral contact points of the BCS-TKA design compared with non-weight-bearing in the mid-range of knee flexion, the amount of anterior translation was small overall. Therefore, BCS-TKA provides good stability during high-flexion weight-bearing activities. However, BCS-TKA is associated with high rate of the anterior engagement during early flexion. Therefore, understanding a patient ’s activities is an important factor when selecting the most appropriate TKA method. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Mid-range reciprocal anterior –posterior femoral translation or laxity corresponds to minimal constraints of the ACL and PCL, and may represent a natural motion character of normal knees.

ConclusionThe measurements using 3D-reconstructed CT images confirmed the great variability of the overall lower limb alignment in non-osteoarthritic knees.

The evolution of femoroacetabular impingement surgical management as a model for introducing new surgical techniques
AbstractIntroducing new surgical techniques and concepts can be difficult. There are many hurdles to overcome initially, such as the learning curve, equipment and technique development, before a standard of care can be established. In the past, new surgical techniques have been developed, and even widely accepted, before any scientific evaluation has been made. At that stage, it may be too late properly to evaluate the effectiveness of treatments, as the objectiveness and/or randomisation process may be obstructed. Since the introduction of evidence-based medicine (EBM), there have been high standards of scientific rigour ...

Where indicated, the addition of osteotomy or ACL reconstruction achieves results similar to patients undergoing simple meniscal transplantation in stable and normally aligned knees. Survivorship is lower in patients with full-thickness chondral loss and future treatments should, therefore, be directed at improving success in this at-risk group.
