Planned Realignment Osteotomies Ahead of Knee Arthroplasty for Pronounced Joint Malalignment: A Case Report in Hereditary Multiple Exostoses Disease.

Various approaches have been reported to achieve correctly aligned total knee arthroplasty in cases of knee arthritis with pronounced extra-articular bone malalignment. Revision instrumentation and implants have enabled bone correction coincident with knee arthroplasty in notable tibial and/or femoral deviation, however increasing operative complexity and inherent risks. In the presented patient with hereditary multiple exostoses disease and progressing knee arthritis for extra-articular malalignment, elected treatment strategy was to primarily correct joint plane deformity through femoral and tibial osteotomies, ahead of and preparing for later knee arthroplasty.

Arthroscopic Synovectomy in Bilateral Lipoma Arborescens.

Introduction: Lipoma arborescens (LA) is an uncommon condition that consists of a villous lipomatous proliferation of the synovial membrane. Open synovectomy has been previously selected as a curative treatment option. In recent years, some authors have published good results with arthroscopic interventions.

Intra-articular giant synovial osteochondroma: case reports of the ankle and knee joint.

Two cases of giant intra-articular osteochondromas (knee and ankle joint) are reported; pathologically they are rare representations of synovial chondromatosis. A 17-year-old man presented with a tumorous mass which had been localized in his left ankle for many years, increasing in volume during the last months. The lesion was removed by posteromedial ankle arthrotomy.
