Although the use of constrained cemented arthroplasty to treat distal femoral fractures in elderly patients has some practical advantages over the use of techniques of fixation, concerns as to a high rate of loosening after implantation of these prostheses has raised doubts about their use.

We studied 40 patients in whom the patella was not severely deformed and who were undergoing primary total knee arthroplasty (TKA) for osteoarthritis by one surgeon using one type of prosthesis. They were randomly allocated either to have the patella retained or resurfaced with a cemented, all-polyethylene component regardless of the state of the patellar articular cartilage. Apart from removal of osteophytes, no surgery was undertaken on the retained patellae. All 38 surviving patients were evaluated at three years using the HSS knee score and a new, specifically designed Patellar score (maximum score of 30). No

In a randomised controlled pragmatic trial we
investigated whether local infiltration analgesia would result in earlier
readiness for discharge from hospital after total knee replacement
(TKR) than patient-controlled epidural analgesia (PCEA) plus femoral
nerve block. A total of 45 patients with a mean age of 65 years
(49 to 81) received a local infiltration with a peri-articular injection
of bupivacaine, morphine and methylprednisolone, as well as adjuvant
analgesics. In 45 PCEA+femoral nerve blockade patients with a mean
age of 67 years (50 to 84), analgesia included a bupivacaine nerve
block, bupivacaine/hydromorphone PCEA, and adjuvant analgesics.
The mean time until ready for discharge was 3.2 days (1 to 14) in
the local infiltration group and 3.2 days (1.8 to 7.0) in the PCEA+femoral
nerve blockade group. The mean pain scores for patients receiving
local infiltration were higher when walking (p = 0.0084), but there
were no statistically significant differences at rest. The mean
opioid consumption was higher in those receiving local infiltration. The choice between these two analgesic pathways should not be
made on the basis of time to discharge after surgery. Most secondary
outcomes were similar, but PCEA+femoral nerve blockade patients
had lower pain scores when walking and during continuous passive
movement. If PCEA+femoral nerve blockade is not readily available, local
infiltration provides similar length of stay and similar pain scores
at rest following
