Purpose: The lessor saphenous vein is an anatomical index in various surgical methods involving an approach to the popliteal fossa. However, occasionally, there have been some cases where the surgical process was difficult because the lessor saphenous vein was not found in the popliteal fossa during the operation process. The aim of this study is to determine the frequency of the anatomical variation of lessor saphenous vein not found in the popliteal fossa with a review of the literature. Materials and Methods: This study was conducted on 83 cases of selective neurectomy for hypertrophic calf performed in our clinic from March 1997 to June 2013. There were 42 patients, with a mean age of 32.8 years old. We confirmed the existence of the lessor saphenous vein in the popliteal fossa during the operation process. Results: Among 83 cases during this study period, the lesser saphenous vein was not found in four cases. In one patient, no lesser saphenous vein was found on either side of the popliteal fossa, and in two patients, no lesser saphenous vein was found on the left side of the popliteal fossa. As a result, the frequency of variation was found to be 4.8%. Conclusion: Due to the anatomical variation of the lessor saphenous vein, it may not be found in the midline of the popliteal fossa. Based on the literature review, several possibilities for failure to observe the lesser saphenous vein could be suggested. If surgeons are well aware of these possibilities, the steadier operation could be performed.

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.

A 38-year-old male was admitted to our hospital due to painful swelling of his right popliteal fossa. He had been kicked in his right popliteal fossa during a soccer game about three weeks earlier. Computerized tomographic angiography of the lower extremity demonstrated a 4-cm-wide, 3-cm-long aneurysmal change of the popliteal artery. He underwent aneurysmectomy and graft interposition using a great saphenous vein graft. Pathologic findings of the resected specimen were consistent with those of a pseudoaneurysm.

Purpose: Malignant melanoma of the lower extremity is well known to metastasize to the lymph nodes of the groin. However, in rare cases, the initial site of the nodal disease can be the popliteal fossa. As of yet, there has not been any report on cases with popliteal lymph node metastasis in Koreans. In the following report, authors would like to present two cases of popliteal node metastasis. Methods: A 60 - year - old male patient presented with nodular mass at his left sole. He had popliteal node metastasis detected on preoperative positron emission tomography(PET). Another 67 - year - old man presented with pigmented lesion at his right heel. He also had popliteal node metastasis detected on the MRI. They underwent wide excision of the primary lesion with popliteal node dissection. Results: In the first case, $2.5{\times}2.5cm$ sized metastatic melanoma in popliteal node was pathologically confirmed. There were no postoperative complications, and to date(18 months after the surgery), the patient is alive with no evidence of disease. In the second case, multiple(4) metastatic melanoma in popliteal nodes was confirmed. The patient is alive, but has had interferon therapy for liver metastasis. Conclusion: By increasing the use of lymphoscintigraphy or PET as a preoperative diagnostic work - up for metastasis, even popliteal node metastasis undetectable in a physical exam becomes detectable. When metastatic lymph node is found, node dissection is the standard of care. Therefore, it is essential that we know the anatomy and surgical technique for popliteal lymph node dissection.

Soft tissue sarcomas of popliteal fossa are rare, accounting for less than 5% of all soft tissue sarcomas of the extremities. In an extracompartmental space such as the popliteal, cubital fossa and inguinal space, where major vessels and nerves traverse, performing resections with wide margin is difficult and sometimes marginal margin is inevitable for limb salvage. For popliteal tumor resection, posterior approach would be a classic method. For tumors with small size and not adherent to surrounding structures, tumor is easily resected by this approach and dissection of nerve sheath or adventitia of vessel. On the contrary, tumors of large size and infiltrating the posterior structure of knee joint may show difficulty in en-bloc resection itself. These cases were candidates for amputation. Furthermore, tumors involving both popliteal fossa and anterior compartment usually had no choice but to have an amputation to prevent local recurrence. We regarded soft tissue sarcoma showing this kind of presentation as bone tumor having extraosseous mass. We performed wide en-bloc resection of proximal tibia and fibula along with sarcoma involving both compartment on liposarcoma of 47-year old man.

Wiring techniques in the fixation of patellar fracture are commonly used. Rigid fixation is essential for early rehabilitation. Breakages of wires after the fixation of patellar fracture are common with extracapsular migration if not removed for long term. But, we experienced a case of patellar fracture with early breakage of wiring and migration of the broken wire fragment into the popliteal fossa through the popliteal hiatus in 64- year-old man and we successfully treated this case, using both arthroscopic and open procedures. So we report this unusual case with a review of current literatures.

At the posterior aspect of distal thigh, major nerves, vessels, muscles and tendons were located. So, if abscess occurs within deep muscular fascia of posterior aspect of distal thigh, it can be widely and deeply spread to proximal thigh, popliteal fossa, posterior proximal leg, surrounding areas of knee joint along deep fascia, muscles and tendons. In that case, it is difficult to eradicate the abscess using antibiotics without surgical drainage and debridement. But, it is often impossible to obtain satisfactory view of operative field with conventional technique and critical damage to major nerves and vessels in the popliteal fossa during operation may occur. We performed endoscopic treatment for extensive deep abscesses occurred in posterior aspect of distal thigh in 64-year-old man, and obtained satisfactory result without injury to the normal structures including major nerves and vessels. So we report this case with a review of relevant literatures.

Purpose: We aim to determine sciatic nerve bifurcation location and depth at the level of the popliteal fossa in Korean female. Materials and Methods: Thirty three subjects were enrolled in Korean female. M-turbo ultrasound system (SonoSite, bothell, WA, USA)with 38 mm high frequency linear array transducer, 13-6 MHz probe was used for ultrasound measurements. With subject lying prone, the location of the sciatic nerve in relation to the popliteal crease and skin to nerve distance were assessed via ultrasound. Analyses were performed with SAS version 9.3 using multiple linear regression. Results: Thirty three subjects were enrolled. Distance from the popliteal crease to the sciatic nerve was 4.5-7.5 (mean 5.7 cm), and the depth of the sciatic nerve from the skin was 1.8-3.2 (mean 2.4 cm). Multiple linear regression for the usefulness of the model has a p value of 0.036, shows between weight and depth. Conclusion: We show that variability exists for sciatic nerve bifurcation location in Korean female, The success rate is creased if consider the relations between weight and depth when performs sciatic nerve block in Korean female. In our study, a sciatic nerve block is recommend that performed 7.5 cm proximal to the crease in the popliteal fossa.

It is a well-accepted tenet that wide surgical margins are necessary for the treatment of soft-tissue sarcomas, and it is still true that the rate of recurrence depends on the adequacy of the surgical margins. Sarcomas that rest directly against bone pose a dilemma for the surgeon. A wide margin is not possible in the literal sense without excision of the bone. Whereas reconstruction of skeletal defects is possible, it adds to the complexity of the surgery and increases potential complications. We report the experience of treatment in a case of synovial sarcoma which located at popliteal fossa adjacent to proximal tibia.
