To our knowledge, no other cases of habitual patellofemoral dislocation in young adults secondary to trauma which occurred in childhood have been described in the literature. Long term follow up results. A year-old woman presented with iatrogenic habitual dislocation of left patella from childhood and pain from past habirual years.
Author information Copyright and License information Disclaimer. Restoration of dynamic stability of the patella by pes anserinus transposition.
They also recommended that various soft tissue procedures are necessary in combination for the correction of habitual dislocation of patella in adults with high grade patella-femoral chondromalacia.
Although the patella was in the femoral trochlear groove in extension, it dislocated laterally with 25 degrees of knee flexion.
Surgical management of congenital and habitual dislocation of the patellar. National Center for Biotechnology InformationU. However it may present in childhood with dysfunction and instability. No single procedure has shown to diwlocation effective in the management of habitual dislocation of patella and a combination of procedures involving proximal and distal reconstruction are recommended.
Quadriceps strength was rated 4 MRC grade. Further flexion is then possible only habbitual the patella is allowed to dislocate, when a full range of motion is readily obtainable. Overall, the cause of dislocation was isolated rupture of the medial stabilizing apparatus of the patella.
Habitual dislocation of patella: A review
Habitual patellar dislocations are rare in adults. She was carrying out her daily activities without much pain or symptoms, but she was never symptom free during this period. The displacement is painless in habitual dislocation, in marked contrast to recurrent dislocation which occurs as isolated episodes, often in response to trauma and is accompanied by pain and swelling. Journal List Indian J Orthop v.
The global IKDC score ot Long-term outcome of surgically treated habitual patel,a dislocation in children with coexistent patella alta: All patellae were small, hypoplastic and hypermobile but no patient had patella alta. A cause of limited knee flexion and elevation of the patella. Arch Orthop Trauma Surg.
Pathophysiology Various pathological factors have been described in the pathogenesis of habitual dislocation of patella.
Late presentation in all these cases was caused by doslocation growth of muscle and bone so that the effect on the knee was not apparent for a number of years.
Habitual dislocation of patella: A review
Vastus intermedius was inspected and divided if tight. It is also termed as obligatory dislocation as the patella dislocates completely with each flexion and extension cycle of the knee and the patient has no control over the kf dislocating as he or she moves the knee 1.
Published online Oct Marmor was the first to perform TKA in an adult patient with congenital dislocation of the patella without reconstructing the extensor mechanism.
After pulling a suture through the holes the femoral attachment point was found and with the help of a temporary pin in the medial epicondyle, favorable anisometry could be obtained the graft relaxed as the knee was flexed and a Corkscrew suture anchor Arthrex, Naples, FL, USA was put in place.
Numerous techniques have been described in the literature for the treatment of patellar dislocations. Corrective osteotomy for genu valgum associated with lateral dislocation of the patella, often failed to control the dislocation; and many habktual with severe genu valgum did not suffer from dislocation of the patella. Very little literature is available on habitual dislocation of patella as most of dislocatiin studies have combined cases of recurrent dislocation with habitual dislocation.
A discussion on the etiology and relationship to recurrent dislocation of the patella. It can be recurrent when dislocation is episodic, habitual when it occurs during each flexion movement of the knee and permanent when it persists in all positions of the knee.
Few years after the surgery, she started noticing the giving way of patella and lived for 38 years without much disability. There was no associated leg dysplasia. The distinction between these groups is important as the surgical treatment for each group is quite different. Factors of patellar instability: EMG studies of vastus lateralis, vastus medialis and pes anserinus muscles were dislcoation in all cases.
Contracture of the deltoid muscle in the adult after intramuscular injections. During surgery the tight lateral bands were released from the patella and the incision was continued proximally, lateral to the rectus femoris tendon, thus fully releasing the vastus lateralis.
Raghuveer K Reddy and Vamsi Kondreddi 1. Jeffreys in described an abnormal attachment of the iliotibial tract to the patella, producing habitual dislocation in flexion. They believed that even in the presence of severe ligamentous laxity, development of the trochlear groove could be expected during the remaining growth when the patella is realigned at a young age.
Treatment of habitual dislocation of patella in an adult arthritic knee
Comparative weight-bearing X-ray lateral view: Habitual dislocation of the patella in flexion. In recurrent dislocations, there were no contractures of the soft tissue lateral to the patella, but medial stabilisation was found to be weak.
There was no recurrent patella or apprehension.
