“…Turnipseed and Pozniak treated 12 such patients with surgical release of the soleus from its tibia1 attachments, resection of its fascia1 band and resection of the plantaris muscle. * They believe that the cause of symptoms in these patients is repeated trauma to the popliteal nerve due to its lateral impingement by the soleal sling during repetitive active plantar flexion.8 This differs from the findings of Chernoff et al 5 Out of the eight patients in our series, only one had a classic medial deviation of the popliteal artery which traversed through the medial head of the gastrocnemius, and required a vein bypass graft for an occluded segment of the popliteal artery. The popliteal fossa was anatomically normal in all other patients.…”

“…This operative step is well supported by the MRI findings of Chemoff et a/., which showed compression of the popliteal artery between the medial head of gastrocnemius and the plantaris and between the plantaris and popliteus muscles. 5 One patient (F) had return of claudication at a distance of over a kilometre particularly during long marches and is at present being treated conservatively. Postoperative duplex and angiogram at 3 months in this patient were normal.…”

Background: Classic popliteal artery entrapment is caused by the abnormal relationship between the popliteal artery and the medial head of the gastrocnemius, resulting in repetitive arterial compression and trauma. There is, however, a distinct subset of calf claudicants who have an anatomically normal popliteal fossa but can occlude the popliteal artery by repetitive vigorous exercise which involves active plantar flexion with or without extension at the knee joint. Methods: Eight patients who led a vigorous athletic lifestyle were evaluated with duplex scan and biplane angiogram after being referred for bilateral calf claudication. They were found to have significant stenosis or occlusion of the popliteal artery with active plantar flexion. All patients had transection of the medial head of the gastrocnemius muscle with release of any vascular bands tethering the popliteal artery. Results: Seven of the eight patients had complete relief. One patient noticed return of claudication at long distances, but a postoperative angiogram was normal. In all patients postoperative duplex scan showed no stenosis or occlusion of the popliteal vessels with the foot in active plantar flexion and the knee in extension. Conclusions: Functional popliteal artery entrapment is becoming a significant cause of disabling claudication in young athletic individuals and needs to be diagnosed accurately for appropriate treatment. This condition is becoming well known with the incorporation of sports in the daily routine of most young people.

“…60,[62][63][64] One study demonstrated popliteal artery occlusion on provocation in 69% of asymptomatic individuals using Doppler US (ABPI) and MRA. 61 No significant differences in the prevalence of popliteal artery compression were found between "athletic" and "nonathletic" asymptomatic individuals, although it is noteworthy that definitions of "athleticism" were based on unclear, subjective, or self-reported criteria. 58,60,[62][63][64] Two studies reported differing prevalences of popliteal vein compression in the asymptomatic population detected by duplex US imaging on provocation (20.5% and 100%).…”

A large volume of predominantly retrospective clinical data exists on PES. A subset of studies describe a significant failure rate after surgery, but study quality is insufficient to derive robust conclusions allowing recommendation of any one particular diagnostic modality or operative procedure over another. Improvements in management of this condition are unlikely to result from publication of further retrospective case series, and clinicians should concentrate on prospectively collected data with predefined inclusion criteria, outcome measures, follow-up protocols, and transparent standardized reporting criteria.
