The most common causes of posterior and posterolateral knee pain (besides referred pain) are knee joint effusions, tendinitis of the hamstring tendons, Baker cyst (semi-membranous cyst), bursitis, meniscal pathologies such as tears and ganglions and lesions of the anterior cruciate ligament. Less common causes include popliteus and gastrocnemius tendinitis, arthrofibrosis after trauma, posterior cruciate ligament sprains, deep venous thrombosis and/or irritations of the common peroneal nerve. We present one patient with posterolateral knee pain after a minor contusion. Magnetic resonance imaging revealed a degenerated posterior horn of the lateral meniscus and a somewhat unclear polypoid structure in the intercondylar region. As the posterior component of the pain persisted even after an arthroscopic partial meniscectomy, an operative revision was performed. A small ganglion of the sheath of the popliteus tendon was found and excised. The patient was immediately relieved of his pain after this procedure. To our knowledge this is the first report concerning a ganglion of the sheath of the popliteus tendon causing posterior knee pain. A similar pathology of the popliteus tendon has been described earlier but at a different localisation (in the hiatus), simulating a parameniscal cyst.

Deep venous thrombosis (DVT) is a major health problem and is estimated to have an incidence of 600,000 cases per year. Clinical signs and symptoms of DVT are unreliable. If clinical signs alone were used to diagnose DVT, 42% of patients would receive unnecessary anticoagulation therapy. Most patients evaluated with ultrasonography (US) do not have DVT. The key to making a precise diagnosis is recognizing the characteristics of various diseases on US images. The anatomic approach is the most useful strategy for characterizing the spectrum of pathologic conditions seen in patients with symptoms that simulate DVT. The inferior extremity can be divided into four regions-inguinal, thigh, popliteal, and lower leg-with the rough limits defined for each as they are examined at US. The differential diagnoses affecting the lower extremities include infectious, neoplastic, traumatic, inflammatory, vascular, and miscellaneous entities. Some pathologic conditions seen in the inguinal region are adenopathies, lymphangitis, soft-tissue tumors, hematomas, adductor tendonitis, and hernias. In the thigh, cellulitis, myositis, abscess, benign and malignant tumors, and sports-related lesions are seen. In the popliteal region, cellulitis, arthritis, benign and malignant masses, muscle contusions, ruptured popliteal cysts, and thrombophlebitis are seen. And in the lower leg, cellulitis, lipomas, tennis leg, superficial thrombophlebitis, tendonitis, and soft-tissue hydrostatic edema secondary to cardiac and renal failure can simulate DVT.

To evaluate the effects of micro-arc oxidation (MAO) coating on the outcomes of a grit-blasted tapered-wedge stem in total hip arthroplasty (THA), we performed a retrospective review of 141 THAs using MAO coated stem for a minimum of 5years and compared them to 219 THAs using the same geometry stem without MAO coating. Harris hip score improved from 43.7 points preoperatively to 93.9 points postoperatively. No hips were revised for aseptic loosening. Complications included one squeaking hip, one iliopsoas tendonitis, and one deep vein thrombosis. Postoperative Harris hip scores, WOMAC scores, UCLA activity scores, stem stabilities, and complication rates did not differ between the groups. After medium-term follow-up, our findings did not support the use of MAO coating on grit-blasted tapered-wedge stem to improve clinical outcomes.
