New Era's knee systems are designed to increase flexion stability while optimizing patellar tracking, rollback and rotation and also focus on minimizing lateral retinacular tightness.
When surgery is indicated, lateral releases should be avoided; lateral retinacular lengthening is the better option because it preserves the anatomical bridle that keeps the knee cap tracking properly, Dr.
For example granivorous/herbivorous carabids have evolved a large retinacular ridge on their mandible, which is used to grind seeds (Acorn & Ball 1991).
Significant cam impingement was noted, and osteoplasty was performed from the region of the medial synovial fold to the lateral retinacular vessels, which were preserved.
Furthermore, we should not underestimate the mobilization of the DIP to prevent adhesions of lateral bands, of the oblique retinacular ligaments and to prevent joint stiffness.
Anatomical structures with sensory nerve supply include the patellar tendon, retinacular tissue, bursae, synovial tissue and the fat pads.
Imbalance between these two muscles can lead to subluxation, and lateral patellar retinacular tightness can result in tilt of the patella.
A canthoplasty with a periosteal flap or a fascia lata graft to correct lateral retinacular dehiscence may also be necessary.
Sampson and Badalamente et al (6) commented that tendovaginitis is a more accurate term to describe the condition than tenosynovitis because the inflammatory changes are in the retinacular sheath and peritendinous tissue rather than in the tenosynovium.
Anterior retinacular injuries are also a rare occurrence.
With the advent of arthroscopy, lateral retinacular release was done through the scope.
In full extension, the loss of the medial retinacular structures resulted in the largest reduction in force necessary to displace the patella 10 mm laterally.
