Instability is a common indication for early
revision after both primary and revision total knee arthroplasty
(TKA), accounting for up to 20% in the literature. The number of
TKAs performed annually continues to climb exponentially, thus having
an effective algorithm for treatment is essential. This relies on
a thorough pre- and intra-operative assessment of the patient. The
underlying cause of the instability must be identified initially
and subsequently, the surgeon must be able to balance the flexion
and extension gaps and be comfortable using a variety of constrained
implants. This review describes the assessment of the unstable
The rate of peri-prosthetic infection following
total joint replacement continues to rise, and attempts to curb
this trend have included the use of antibiotic-loaded bone cement
at the time of primary surgery. We have investigated the clinical-
and cost-effectiveness of the use of antibiotic-loaded cement for
primary

We conducted a meta-analysis, including randomised
controlled trials (RCTs) and cohort studies, to examine the effect
of patient-specific instruments (PSI) on radiological outcomes after
total knee replacement (TKR) including: mechanical axis alignment
and malalignment of the femoral and tibial components in the coronal,
sagittal and axial planes, at a threshold of >
3º from neutral.
Relative risks (RR) for malalignment were determined for all studies
and for RCTs and cohort studies separately. Of 325 studies initially identified, 16 met the eligibility criteria,
including eight RCTs and eight cohort studies. There was no significant
difference in the likelihood of mechanical axis malalignment with
PSI versus conventional
