The pain around the posterior knee, called 'popliteal fossa', has been known to be caused by a variety of disease entities. Venous malformation is a very rare cause of popliteal area pain, and its diagnosis is frequently delayed, missed, or given incorrectly. Here, we report a case of a patient with popliteal fossa pain for 2 years and was diagnosed as intramuscular venous malformation using ultrasound.

Background: Transcutaneous electrical nerve stimulation (TENS) has been used widely, but its effects are controversial. This is probably due to the varying intensity and type of pain. We designed a study to assess the effects of the TENS on the RIII nociceptive flexion reflex as the resting pain level and the temporal summation as a repeated, movement related pain in 7 normal volunteer subjects. Methods: High frequency (80 Hz), non-noxious TENS was applied over the left popliteal fossa for 20 minutes. Ipsilateral RIII reflexes induced by single electrical stimulus and temporal summation of pain responses to repeated stimuli (five stimuli at 2 Hz) were recorded before, during (just before stopping), and subsequently at 20 minutes after TENS. Results: R (III) nociceptive flexion reflex activity during and after TENS was more significantly decreased than before treatment. However, the temporal summation threshold was not changed. Conclusions: We conclude that high frequency, non-noxious TENS could be effective on resting pain relief in the same segment but not on the movement related pain.

This journal reports three cases diagnosed with schwannomatosis in which no clinical symptoms of type 2 neurofibromatosis. The chief complain was pain. In adolescence and adult group, all masses were found. The locations were brachial plexus, popliteal fossa and hand. No hearing impairment, vertigo, tinnitus and visual disturbance was observed in any of the case. Family history was negative. In all cases, there was no evidence of vestibular schwannoma on cranial MRI imaging study. In all cases, Tinel sign was positive. Pathologic diagnosis was positive for schwannoma. Further study and case collection is needed to idenity the clinical manifestation, clinical course and genetic characteristic of schwannomatosis.

The authors report one case of isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament. A 13 years old boy was admitted for right knee pain and swelling after the soccer injury on his knee. Hemarthrosis and posterior instability were present. Simple roentgenographic examination showed an isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament. Open approach through the popliteal fossa was used and bony fragment was fixed into its bed using pull-out sutures. Postoperatively, a long leg cast was applied for 4 weeks. The patient was followed for 6 months. He returned to his previous activity levels. There was no residual laxity. Isolated avulsion of the posterior cruciate ligament from the tibia before the epiphyseal fusion is very rare in children. We reported one case of our experience and its result.
