Pre-operative variables are increasingly being
used to determine eligibility for total knee replacement (TKR).
This study was undertaken to evaluate the relationships, interactions
and predictive capacity of variables available pre- and post-operatively
on patient satisfaction following TKR. Using nationally collected
patient reported outcome measures and data from the National Joint
Registry for England and Wales, we identified
22 798 patients who underwent TKR for osteoarthritis between August
2008 and September 2010. The ability of specific covariates to predict
satisfaction was assessed using ordinal logistic regression and
structural equational modelling. Only 4959 (22%) of 22 278 patients
rated the results of their TKR as ‘excellent’, despite the majority
(71%, n = 15 882) perceiving their

A prospective, randomised, controlled trial compared two different techniques of high tibial osteotomy with a lateral closing wedge or a medial opening wedge, stabilised by a Puddu plate. The clinical outcome and radiological results were examined at one year. The primary outcome measure was the achievement of an overcorrection of valgus of 4°. Secondary outcome measures were the severity of pain (visual analogue scale),

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
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
