[Simultaneous existence of unicameral bone cysts involving the femur and ischium].

We report a 30-year-old male patient with two unicameral bone cysts (UBC) simultaneously located in the proximal third of the right femur and ipsilateral ischium ramus, respectively. Fine needle biopsies were attempted for both lesions. Biopsy of the femoral lesion under local anesthesia was unsuccessful, so an open biopsy was performed which confirmed the diagnosis of UBC.

Yttrium-90 radiation synovectomy in knee osteoarthritis: a prospective assessment at 6 and 12 months.

Objective: To assess the outcome of yttrium-90 radiation synovectomy at 6 and 12 months in patients with knee osteoarthritis unresponsive to systematic or local medical treatment.

Methods: Consecutive patients with osteoarthritic knee pain resistant to conventional therapy and submitted to intraarticular yttrium-90 treatment because of synovial inflammation, as demonstrated by early-phase bone scintigraphy, were prospectively evaluated at 6 and/or 12 months. The assessment of the outcome of treatment was based on self-reporting of relief of knee pain limiting daily activities, measured as percentage reduction of the pretherapeutic joint discomfort with a Visual Analogue Scale.

Baker's cysts in knees with chronic osteoarthritic pain: a clinical, ultrasonographic, radiographic and scintigraphic evaluation.

This study aimed to determine the ultrasonographic prevalence of Baker's cysts in knees with chronic osteoarthritic pain and investigate for cysts correlates and relationships with scintigraphically established synovitis. Consecutive patients with chronic osteoarthritic knee pain underwent clinical examination, X-rays, ultrasonography and early-phase bone scintigraphy. Eighty-nine Baker's cysts were detected in 328 knees with chronic osteoarthritic pain (27%), whereas one cyst was identified among the 54 non-osteoarthritic knees (2%, P<0.

Recurrent spontaneous hemarthrosis after total knee arthroplasty successfully treated with synoviorthesis.

A case of spontaneous recurrent hemarthrosis--due to developed hypertrophied synovium--after total knee arthroplasty is reported. The patient was successfully treated with radiosynovectomy. The first hemorrhage occurred 18 months after the total knee arthroplasty.
