Does medial retinaculum tear require surgery?
Most first time MPFL injuries can be treated non-surgically with NSAIDs and immobilization. It’s then followed by physical therapy to strengthen the muscles around the knee. Your physician may recommend surgery if the injury is more severe, or if there are small pieces of detached bone or cartilage in the knee.
What is the medial retinaculum of the knee?
The medial patellar retinaculum is a tendon of the knee that crosses the knee joint on the medial side of the patella. The medial patellar retinaculum is the branch of the tendon of insertion of the quadriceps femoris that crosses the knee on the medial side of the patella.
What is the lateral retinaculum of the knee?
The lateral retinaculum is the fibrous tissue on the lateral (outer) side of the kneecap (patella). The kneecap has both a medial (on the inner aspect) and a lateral (on the outer side) retinaculum, and these help to support the kneecap in its position in relation to the femur bone underneath it.
Is lateral Retinaculum a ligament?
It is composed of Lockwood’s ligament (inferior suspensory ligament), the lateral extension or horn of the levator aponeurosis, the continuations of the pretarsal and preseptal muscles, and the check ligament of the lateral rectus muscle.
What is lateral release of the knee?
Lateral release surgery of the knee is an arthroscopic surgery that is performed through three small incisions in the knee. Your doctor will cut through a tight group of tendons in the kneecap to allow the kneecap to move correctly into the proper groove, restoring normal alignment.
What happens when you cut the flexor retinaculum?
When the FR is cut in longitudinal direction over the median nerve, the median nerve elevates between the two borders of the retinaculum and the scar tissue between the median nerve and the flexor retinaculum leads to nerve constriction.
How is the diagnosis of medial retinaculum made?
Medial Retinaculitis-Rare condition seen almost exclusively in runners. Likely to be caused by a fatigue tear in the medial capsular insertion into the patella (Dutton). Diagnosis can be determined by a positive bone scan in medial edge of patella (Dutton). Fibrous tissue on the lateral side of the patella that helps to control patellar tracking.
What is the origin of the medial patellar retinaculum?
The medial patellar retinaculum is a fibrous expansion comprising of superficial and deep layers. The superficial layer originates from the lowest fibers of the vastus medialis muscle, sartorius and the medial collateral ligament. The deep layer has contributions from the medial patellofemoral ligament and fascial thickenings.
What to do about a torn medial retinaculum?
Pain and tenderness on structure (medial side of patella). May be the source or a contributing factor of patella femoral pain syndrome (PFPS), repetitive or severe injury may lead to stretched/weakened or torn medial retinaculum (Dixit). Intervention: Rest and reduction in exercise or workload and possibly surgery.
How is the lateral retinaculum incised in the knee?
From the inside of the knee the lateral retinaculum is incised, from the inside, allowing the kneecap to untilit itself. Releasing the tight lateral tissues takes the strain off the medial tissues which are causing pain.
