NITINOL ENGINE DEVELOPMENT [PDF]

, 1976
The objective of this project is to determine the feasibility of applying the shape-memory effect in certain intermetallic compounds (particularly ''55 Nitinol'') to the conversion of low temperature heat energy to mechanical work by means of solid state heat engines.

All‐Inside Anterior Cruciate Ligament Reconstruction With Accurate Measurement Technique

Arthroscopy Techniques, EarlyView.
Abstract The all‐inside anterior cruciate ligament reconstruction technique is characterized by closed bone sockets for anterior cruciate ligament graft passage and typically adopts suspensory fixation instead of screw fixation. Inaccurate determination of the intra‐articular length (IAL) of the graft is associated with an elevated risk of graft ...

A Tension‐Controlled Arthroscopic Technique for Fixation of a Glenolabral Articular Disruption Lesion in an Overhead Athlete

Arthroscopy Techniques, EarlyView.
Abstract Glenolabral articular disruption lesions are rare post‐traumatic injuries that occur after shoulder instability events particularly in young, high‐demand athletes. Managing these injuries can be challenging especially in overhead athletes who require a degree of physiologic laxity to preserve throwing mechanics.

Transtibial Medial Meniscus Root Repair With Simplified Cross‐Bar Suture Configuration and Knotless Centralization

Arthroscopy Techniques, EarlyView.
Abstract The significance of medial meniscus root tears on articular cartilage degeneration of the medial compartment is well recognized. There is a consensus among peer‐reviewed literature on the importance of tear fixation over partial meniscectomy or observation in the appropriately indicated patient. Recent attention has been paid to the importance
