Soft-tissue landmarks for tibial baseplate rotational alignment in total knee arthroplasty: A cadaveric study.

The tip of the tibial tubercle (TTT) is used to assess tibial baseplate rotation in total knee arthroplasty (TKA); however, it can be difficult to palpate and visualize intraoperatively. Several more easily accessible soft-tissue structures have been proposed as intraoperative assessments, including the patellar tendon's medial border (MBPT) and the junction of the medial third of the patellar tendon (mt-PT). No studies have described the relationship between the TTT and these proposed landmarks.

Intra-articular Myxoma Arising from the Scapholunate Ligament: A Rare Cause of Dorsal Wrist Swelling.

The differential diagnosis of a dorsal wrist swelling includes ganglion, lipoma, cutaneous tumors, and benign peripheral nerve sheath tumors, with ganglions being the most common. We present the case of a myxoma arising from the dorsal scapholunate ligament mimicking a dorsal wrist ganglion. Volar wrist joint myxomas have been previously reported, but this is the first report of a myxoma arising from the dorsal side of the wrist joint.

The accuracy of femoral component rotational measurements using computed tomography-a cadaveric study.

Background: CT scans can be used to assess the rotational alignment of the femoral component following total knee arthroplasty (TKA). This is done by calculating the posterior condylar angle (PCA). However, the methods used may not account for the biomechanical functionality of the TKA components.

Homing of mesenchymal stem cells: mechanistic or stochastic? Implications for targeted delivery in arthritis.

Mesenchymal stem cells (MSCs) are multipotent cells with the capacity to undergo chondrogenic differentiation. Systemically administered MSCs have been shown to preferentially accumulate at sites of tissue damage and inflammation, thus MSC-based therapy holds great promise for the treatment of inflammatory diseases such as RA. Modulation of MSC homing may allow targeted delivery of systemically administered MSCs to damaged articular cartilage, where they can suppress immune-mediated cartilage destruction and contribute to cartilage repair via a combination of chondrogenic differentiation and paracrine stimulation of intrinsic residual repair.

Case-based anatomy teaching: a viable alternative?

Background: Over the last two decades, there has been a decline in the amount of time available for anatomy teaching in the medical undergraduate curriculum, and new methods of anatomy teaching have been adopted for pragmatic reasons, with little evidence base to support their proposed educational benefits. This study seeks to establish the effect of a case-based teaching method on students' confidence in anatomy.

Methods: Forty-three student volunteers in the clinical phase of the Glasgow medical course were given weekly anatomy teaching sessions based on clinical case presentations over 4 weeks.
