I n t r o d u c t I o n:

  • The primary pathogenesis of popliteal cysts in adults is a one-way valvular mechanism allowing flow of joint fluid from knee to bursa.

  • The therapeutic approach for Baker’s cyst has shifted towards arthroscopic techniques to confirm the associated intra-articular lesions.

In the name of god

I n t r o d u c t I o n:

  • The aims of this study include determining the frequency of accompanying intra-articular lesions as well as comparing the outcomes of treating popliteal cyst with arthroscopy and open surgery.


In the name of god

Method and Materials:

Design: Prospective Study

Pilot Study (Rauschning and Lindgren’s Grading )


In the name of god

Method and Materials:

Inclusion Criteria:

Symptoms (pain, swelling, and limited ROM)

Sonographic Diagnosis

Exclusion Criteria:

Grade 0 and 1 of Raushning and Lindgren (treated conservatively)

Any Other types of Cysts (Meniscal and Synovial Cysts)

Cases:

45 patients


In the name of god

Method and Materials:


In the name of god

Method and Materials:

  • Evaluation of Outcomes:

  • Demographic characteristics

  • Associated lesions

  • Rate of reduction of symptoms (using Rauschning and Lindgren scale) before and three months after surgery.

  • Recurrence (One year after surgery using sonography)


In the name of god

Results:

Age:48.42 ± 8.55 years

Gender: 26 men and 19 women


In the name of god

Results:

Disorders associated with popliteal cyst in study population

All patients (100%) had at least one associated knee lesion.


In the name of god

Results:

Rauschning and Lindgren’s Grading


In the name of god

Results:

  • Treatment outcome:

  • Grade 0 : Excellent

  • Grade 1 : Good


In the name of god

Results:

Rauschning and Lindgren’s grading before surgery:

There was no statistically meaningful difference between 2 groups (P=0.388)


In the name of god

Results:

Rauschning and Lindgren’s grading after treatment:

Reduction in RL grade between groups was not significant.

Discussion:

  • Popliteal Cysts are always associated with intra-articular pathology. The most frequent concomitant lesion is medial meniscustear.

  • Sansoneet al. 1999  Anteromedial portal

  • Takahashi et al. 2005  Posteromedial portal

  • Ahnet al. 2007  Posteromedial cystic portal

  • Sinha et al. 2009  Methylene blue dye-assisted decompression


In the name of god

conclusion:

  • According to non-meaningful statistical relation between treatment methods and 3months clinical evaluation results, it is revealed that executing the valve and evacuating the cyst would suffice to treat the popliteal cyst and further surgical excision of cyst is not necessary.
