Further flexion is then possible only if the patella is allowed to dislocate, when a full range of motion is readily obtainable. J Bone Joint Surg Br.
The global IKDC score was Successful results require combination of these procedures, depending on clinical and intraoperative findings on an individual basis. Received Aug 18; Accepted Sep They recommended early surgery and showed gradual improvement in the development of the femoral trochlear groove in response to the re-centering of the patellar mechanism.
The passive patwlla patellar tilt test was negative since the soft tissue attachment to the lateral border of the patella was diffusely stiff and tight. Williams reported clinical presentations and pathophysiology in patients with quadriceps contractures.
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 patella dislocating as he or she moves the knee 1.
Isolated repair of MPFL was possible because there was no retraction of the knee extensor apparatus or predisposing bone factors, which would have required further surgical procedures.
Total knee arthroplasty in bilateral congenital dislocation of the patella: The displacement is painless in habitual dislocation, in marked contrast to recurrent dislocation which occurs as isolated episodes, often in response habital trauma and is accompanied by pain and swelling.
On the femoral side, there was no crossing sign or spurs, and the depth of the trochlear groove was normal.
Habitual dislocation of patella: A review
Treatment is difficult, and often associated with significant morbidity. We believe that the soft tissue surgery as primary procedure will buy additional time for patient hanitual delay the TKA and proper soft tissue balancing will improve the longevity and clinical outcome of the definitive procedures.
Bone factors probably had only a small role in the dynamic stability of the patella. Factors of patellar instability: Radiographs showed well reduced patella in both lateral, anteroposterior view and skyline view [ Figure 2 ].
In our patient, radiographic results have shown that instability was not caused by bone anomalies. Author information Copyright and License information Disclaimer.
Habitual dislocation of patella: A review
Table didlocation Contents Alerts. Introduction Habitual dislocation of patella is a condition where the patella dislocates whenever the knee is flexed and spontaneously relocates with extension of the knee. At final followup two years postoperatively, the patient was pain-free.
In case of no retraction of the knee extensor apparatus or predisposing bone factors, isolated MPFL reconstruction seems effective in treating confirmed patellar instability. Few cases of habitual dislocations have been reported [ 7 ]. Shen performed combined proximal and distal dislocatikn in 12 adult patients with habitual dislocation of patella.
J Bone Joint Surg Br. A report of two cases. If patella still dislocates after full flexion is achieved, distal realignment is added.
There was no associated leg dysplasia. Arch Orthop Trauma Surg. Subscribe to Table of Contents Alerts.
og Tracking was augmented with MPFL reconstruction using semi-tendinosus tendon and patellar end was fixed with 2. Patela in a separate window. This is followed by complete dissection of vastus lateralis from its attachment to the patella and the lateral side of rectus femoris.
Most cases presented between the ages of 5 and 12 years when the femur is growing disproportionately to the quadriceps. Scoring of patellofemoral disorders. Knee Surg Sports Traumatol Arthrosc. It usually presents after the child starts to walk, and is often well tolerated in children, if it is not painful. Contracture of the vastus intermedius in children. Recurrent dislocation of the patella.
