In Scotland, the number of primary total knee replacements performed annually has been increasing steadily. The price of the implant is fixed but the length of hospital stay is variable. We prospectively investigated all patients who underwent primary unilateral

The use of technology to assess balance and alignment during total knee surgery can provide an overload of numerical data to the surgeon. Meanwhile, this quantification holds the potential to clarify and guide the surgeon through the surgical decision process when selecting the appropriate bone recut or soft tissue adjustment when balancing a total knee. Therefore, this paper evaluates the potential of deploying supervised machine learning (ML) models to select a surgical correction based on patient-specific intra-operative assessments. Based on a clinical series of 479 primary total knees and 1,305 associated surgical decisions, various ML models were developed. These models identified the indicated surgical decision based on available, intra-operative alignment, and tibiofemoral load data.Aims

We suggest that different mechanisms underlie joint pain at rest and on movement in osteoarthritis and that separate assessment of these two features with a visual analogue scale (VAS) offers better information about the likely effect of a
A total of 445 consecutive primary total knee
replacements (TKRs) were followed up prospectively at six and 18 months
and three, six and nine years. Patients were divided into two groups:
non-obese (body mass index (BMI) <
30 kg/m. 2. ) and obese
(BMI ≥ 30 kg/m. 2. ). The obese group was subdivided into
mildly obese (BMI 30 to 35 kg/m. 2. ) and highly obese (BMI ≥ 35
kg/m. 2. ) in order to determine the effects of increasing
obesity on outcome. The clinical data analysed included the Knee
Society score, peri-operative complications and implant survival.
There was no difference in the overall complication rates or implant
survival between the two groups. Obesity appears to have a small but significant adverse effect
on clinical outcome, with highly obese patients showing lower function
scores than non-obese patients. However, significant improvements
in outcome are sustained in all groups nine years after
Aims. We conducted a randomised controlled trial to assess the accuracy
of positioning and alignment of the components in total knee arthroplasty
(TKA), comparing those undertaken using standard intramedullary
cutting jigs and those with patient-specific instruments (PSI). Patients and Methods. There were 64 TKAs in the standard group and 69 in the PSI group. The post-operative hip-knee-ankle (HKA) angle and positioning
was investigated using CT scans. Deviation of >
3° from the planned
position was regarded as an outlier. The operating time, Oxford
Knee Scores (OKS) and Short Form-12 (SF-12) scores were recorded. Results. There were 14 HKA-angle outliers (22%) in the standard group
and nine (13%) in the PSI group (p = 0.251). The mean HKA-angle
was 0.5° varus in the standard group and 0.2° varus in the PSI group
(p = 0.492). The accuracy of alignment in the coronal and axial
planes and the proportion of outliers was not different in the two
groups. The femoral component was more flexed (p = 0.035) and there
were significantly more tibial slope outliers (29% versus 13%)
in the PSI group (p = 0.032). Operating time and the median three-month
OKS were similar (p = 0.218 and p = 0.472, respectively). Physical
and mental SF-12 scores were not significantly different at three
months (p = 0.418 and p = 0.267, respectively) or at one year post-operatively
(p = 0.114 and p = 0.569). The median one-year Oxford knee score
was two points higher in the PSI group (p = 0.049). Conclusion. Compared with standard intramedullary jigs, the use of PSI did
not significantly reduce the number of outliers or the mean operating
time, nor did it clinically improve the accuracy of alignment or
the median Oxford Knee Scores. Our data do not support the routine
use of PSI when undertaking
