An 18 y/o woman comes to the physician because of knee pain that has been presentd for 5 years. Tha pain is prolongued by prolonged sitting and by ging up and down steps. She has 10 degree of hyperextension of both elbows. she becomes sppehensive when laterally directed pressure is applied to the patella. X-ray film shows no abnormalities.



a) Anterior cruciate ligament reconstruction
b) Arthroscopic partial meniscectomy
c) Quadriceps streghtening excersices
d) Sympathetic blockade
e) Total knee replacement
f) Upper tibial osteotomy

Ok I hate orthopedics but here I go. She is a young woman with this typical pain history. When does the pain get worst? She aknowledge gouing dopwn the steps and she has the Cinema Sign!!!... until there she has a Patellar tendinitis (remember going down the stairs to sit at the cinema=Patelar tendinitis ) and apprehensive test means unstable knee. And a negative x-ray film...what can we say? not patella and either bone! right?... and thatīs all! thatīs why I hate orthopedics!!!... Thereīs sopmething made me think, what about elbow?... tendinOsis goes like that with elbow pain! but she only has hyperextension! maybe Ehler Danlos? hehehe.... Well I keep on Patelar tendinitis.. and if itīs so... conservative treatment is the first chioce so Iīll go for C) .
Please frank100 post the right answer!!!!!!!!

The diagnosis here is patellar subluxation (presents in adolescent females, positive apprehension test on pataller movement laterally):

A, B and E do not fit as they have nothing to do with patella
F: upper tibial osteotomy is not doen for this minor reason
D: sympathetic blockade..................why?? How wud that help

Based on thsi I would go for C: Quadricpes strenghtening exercises. One cardinal rule taught in soprts medicine is that the the stability of knee joint can be increased by making the quadriceps stonger. I guess patellar subluxation makes a knee joint less stable and therefore this seems like the best answer.

  #12

Iīll go for C but I am not sure if its patellar subluxation. I think is tendinitis.

  #13

tendinitis for 5 years...?
