Lipoma arborescens is a rare intra-articular lesion, characterised by diffuse replacement of the subsynovial tissue by mature fat cells, producing prominent villous transformation of the synovium. The aetiology of this benign condition is unknown. We describe six cases involving the
Two cases of ganglion arising in the alar folds of the infrapatellar fat pad are reported. Both patients had symptoms of internal derangement of the
We investigated the characteristics of patients
who achieved Japanese-style deep flexion (seiza-sitting) after total knee
replacement (TKR) and measured three-dimensional positioning and
the contact positions of the femoral and tibial components. Seiza-sitting
was achieved after surgery by 23 patients (29 knees) of a series
of 463 TKRs in 341 patients. Pre-operatively most of these patients
were capable of seiza-sitting, had a lower body mass index and a favourable
attitude towards the Japanese lifestyle (27 of 29 knees). According
to two-/three-dimensional image registration analysis in the seiza-sitting
position, flexion, varus and internal rotation angles of the tibial
component relative to the femoral component had means of 148° (. sd. 8.0),
1.9° (. sd. 3.2) and 13.4° (. sd. 5.9), respectively.
Femoral surface contact positions tended to be close to the posterior
edge of the tibial polyethylene insert, particularly in the lateral
compartment, but only 8.3% (two of 24) of

Injuries to the sciatic nerve are an occasional complication of surgery to the hip and acetabulum, and traction is frequently the causative mechanism. In vitro and animal experiments have shown that increased tensile strain on peripheral nerves, when applied for prolonged periods, impairs nerve function. We have used video-extensometry to measure strain on the human sciatic nerve during total hip replacement (THR). Ten consecutive patients with a mean age of 72 years undergoing primary THR by the posterior approach were recruited, and strains in the sciatic nerve were measured in different combinations of flexion and extension of the hip and
Since 1974, we have made a prospective study in Bristol of the results of unicompartmental knee replacement using the St Georg sledge prosthesis. A total of 115

The treatment of osteochondritis dissecans (OCD) in children and adolescents is determined by the stability of the lesion and the state of the overlying cartilage. MRI has been advocated as an accurate way of assessing and staging such lesions. Our aim was to determine if MRI scans accurately predicted the subsequent arthroscopic findings in adolescents with OCD of the
Medial tibial plateaux excised during 46 unicompartmental arthroplasties for osteoarthritis were collected and photographed. The anterior cruciate ligament was intact in all joints. In every case the cartilage and bone erosion was centred anteriorly on the plateau and the posterior cartilage was intact. The site of the lesion and the intact state of the cruciate ligaments taken together explain why varus deformity was observed only in the extended
