..There is a need to develop a method to identify which patients with PTCL will do well so that this subgroup could be treated with UKR...

..The survival rates are similar to those obtained with a standard open approach whereas the function is better. This demonstrates the effectiveness and safety of a minimally invasive surgical approach for implanting the Oxford UKR...

..We conclude that the thresholds proposed by Kozinn and Scott using weight, age, activity, the state of the patellofemoral joint and chondrocalcinosis should not be considered to be contraindications for the use of the Oxford UKR...

..04 and p=0.03) in the different series. The combination of the modified surgical technique and new design with a domed tibial component appears to have reduced the early dislocation rate to an acceptable level...

..In contrast, the results in women have been poor and we do not recommend metal-on-metal resurfacing in women. Continuous follow-up is recommended because of the increasing incidence of pseudotumour with the passage of time...

..As the incidence of pseudotumour is low in men, it appears safe to perform resurfacing in men. However, this study suggests that it is also reasonable to resurface in women with a pre-operative HNR ≤ 1.3...

..In the cementless implants, partial radiolucencies were seen in 7% and complete radiolucencies in none. These differences are statistically significant (p < 0.0001) and imply satisfactory bone ingrowth into the cementless implants...

..Although this study showed no difference between minor overhang or underhang, we would advise against significant underhang because of the theoretical risk of component subsidence and loosening...

..As the relative position of the components and thus component loading are similar to the ACLI UKA, we would expect similar long term survival...

..In summary, ACL reconstruction and Oxford UKR gives good results in patients with end-stage MCOA secondary to ACL deficiency...

..With lateral patellofemoral degeneration the situation is less well defined and caution should be observed...

..This study demonstrates that the minimally-invasive Oxford unicompartmental knee replacement is a reliable and effective procedure...

..However, if the bearing displays suboptimal function (extra-articular, intra-articular impingement or incongruous articulation) the rates of wear increase significantly...

..A simple patellar model demonstrated that the reduced PFA may explain a large proportion of the reduction in QF after single radius TKR...

..However, the results show that at high flexion this design does not achieve normal knee kinematics...

..Because of differences between the radiographic and the operative angles, this may be best achieved by aiming for an inclination of 40 degrees and an anteversion of 25 degrees...

..1mm RMS. The rotational accuracies were between 0.6 degrees and 2.3 degrees which are less accurate than those reported in the literature for TKA, however, the method is sufficient for studying overall knee kinematics...

..Seven cases treated in this manner are reported, of which one of the seven has redislocated. In the remaining six, their clinical outcomes are comparable to the outcomes of those without dislocations...

..Consequently, PS subjects stepped-up more cautiously with a reduced knee flexion moment...

....

..This operation seems to be a viable treatment option for young active patients with symptomatic arthritis of the medial compartment, in whom the anterior cruciate ligament has been ruptured...

..Survival based on revision alone provides an acceptable but inaccurate impression of outcome in younger TKR patients (under 60 years). A true representation of the success of TKR should include pain and function as endpoints...

..Cementless OUKR appears to be safe and reproducible in patients with end-stage anteromedial osteoarthritis of the knee, with radiological evidence of improved fixation compared with previous reports using cemented fixation...

....

..Further work is required to understand the aetiology of pseudotumours so that this complication can be avoided...

..The outcome of revision for pseudotumour is poor and consideration should be given to early revision to limit the extent of the soft-tissue destruction. The outcome of resurfacing revision for other causes is good...

..Following UKR the deductions for malalignment in the American Knee Society score are not justified...

..A posterior marker wire is no longer used in the polyethylene meniscus. Therefore, the rate of fracture, which is now very low, should be reduced to a negligible level...

..At ten years, the mean linear wear rate was 0.02 mm/year. The results from this in vivo study confirm that the device has low ten-year linear wear in clinical practice. This may offer the device a survival advantage in the long term...

..These encouraging results indicate that semi-automated measurement techniques could improve the reliability of radiographic measurements...

..The second aim is to assess whether a correlation exists between the presence of a RLL and the type of tissue that predominates at the interface...

..The definitive treatments of both cystic and solid tumours should be selective arthrotomy and excision biopsy. All patients in this series reported substantial improvement in symptoms following surgery...

..001) in the local anaesthetic group. We conclude that a bolus dose of intra-articular bupivacaine early on the day after surgery dramatically improves pain control after UKR and improves patient satisfaction...

..During this time, they have been modified and used for many different purposes. This paper describes how they should be used and seeks to clarify areas of confusion...

..These differences suggest that surface geometry is a stronger determinant of kinematics than the presence or absence of a cam-post mechanism for these two designs. This may be because the cam-post mechanism is ineffective...
