Many studies have appeared comparing open surgical flexor retinaculum
release to blind injections of corticosteroids into the carpal tunnel, but there is no agreement on which is preferable.
In particular, tightness in the lateral retinaculum
(one of the fibrous bands that hold the patella in alignment) could contribute to the pain by causing the patella to ride laterally, which may contribute to the retropatellar pain of PFPS.
Introduction: The role of the peripatellar retinaculum
as a frontal plane stabilizer of the patellofemoral joint has been well established.
Examination of the amputation specimen demonstrated PVNS penetrating through the retinaculum
and into the popliteal fossa, with destruction of the distal femur.
Pressure on the flexor retinaculum
, which similar to the ante brachial fascia runs parallel to the median nerve, compresses the median nerve, a situation that occurs when using screwdrivers, knives or a jewelry beader.
Normal postoperative findings include a complete surgical defect of the flexor retinaculum
and volar extrusion of the carpal tunnel components through it, with improvement of neural signal changes.
Isolated patellofemoral arthritis can be attributed to abnormal patellofemoral mechanics in the absence of trauma, which can be caused by any combination of patella alta, trochlear dysplasia, increased Q angle, weak or hypoplastic vastus medialis oblique, a contracted lateral retinaculum
, and absent or redundant medial patellofemoral ligament.
Cubital tunnel syndrome occurs as a result of compression of the ulnar nerve between the medial epicondyle, the olecranon and the roof of the tunnel that is formed by the retinaculum
which is also known as Osborne's band or the arcuate ligament.
More persistent symptoms may require a surgical release where the flexor retinaculum
is divided to decompress the median nerve.
Pain due to functional deficits may be a result of the medial quadriceps insufficiency, inflexibility of the lateral retinaculum
, shortening of the hamstrings and gastrocnemius muscles and imbalances between the hip internal-external rotators and the quadriceps-hamstrings, respectively.

and quadriceps muscles to patellar lateral stability- an in-vitro study.
