Effect of lateral meniscus allograft on shoulder articular contact areas and pressures

Lateral meniscus allograft biologic glenoid arthroplasty in total shoulder arthroplasty for young shoulders with degenerative joint disease

“…A study on contact area and pressure on the glenoid showed that the LMA interposition increased the area of contact and decreased force transmission from the humeral head to the native glenoid surface. 5 The LMA is similar in size and shape to the glenoid surface. The LMA has thus been used in the younger, active population for biologic resurfacing in TSA; however, this has not been reported on in larger series.…”

Loss of rotator cuff tendon-to-bone interface pressure after reattachment using a suture anchor

“…The use of this system has been well established in biomechanical studies. 6,10,22,24,40,44 Although this study had the limitations noted previously, it has demonstrated clearly that rotator cuff repairs relax greatly from the moment that the knot is tied, as a mean of only 14% of the maximum contact force remained after 1 hour. This means that contact studies in this or similar situations should use a pressure-measuring sensor that can record transient effects and that the maximum pressure applied during the course of making the repair is not representative of the situation immediately afterward.…”

“…33,43 Bachus et al 3 found comparable results between Tekscan sensors and Fuji film, and Tekscan sensors have been used to measure contact pressures in the knee, 6,26,27 spine, 44 foot, 24,40 and shoulder. 10,22 We consider the ability to record pressure changes, rather than only the maximum applied, to be an advantage for Tekscan sensors.…”

Principles of glenoid component design and strategies for managing glenoid bone loss in revision shoulder arthroplasty in the absence of infection and rotator cuff tear

“…Cadaveric study has shown decreased stress on the underlying glenoid and avoidance of central glenoid contact. 12 Clinical studies have shown successful patient-derived outcomes at early follow-up; however, a significant risk of reoperation has also been noted. 5,27,36 Although these studies have made glenoid resurfacing a potential option in revision TSA, its utility for this specific indication is relatively unknown.…”
