“…Appropriate patient selection and correct clinical indication for UKA are important factors that could affect survivorship. Pre-operative cartilage thickness in the medial compartment appears to affect survival since rerevision rate was found to be 6-fold for knees where there was more than 2 mm of joint space preserved preoperatively [45].…”

“…Third, patients undergoing UKAs are younger compared with patients undergoing TKAs, therefore, their expectations are high, and the results of UKAs in these patients may be disappointing [21]. Finally, there is increasing evidence that patients with mild or moderate OA who undergo knee arthroplasty, even those with severe symptoms, have a higher revision rate than patients with severe arthritis [16,17,19]. These patients may be overrepresented in the UKA group because the less invasive operation may be performed for patients with less severe arthritis.…”

Background Balancing the relative advantages and disadvantages of unicompartmental knee arthroplasties (UKAs) against those for TKAs can be challenging. Survivorship is one important end point; arthroplasty registers repeatedly report inferior midterm survival rates, but longer-term data are sparse. Comparing survival directly by using arthroplasty register survival reports also may be inadequate because of differences in indications, implant designs, and patient demographics in patients having UKAs and TKAs. Questions/purposes The aims of this study were to assess the survivorship of UKA in the context of one large, northern European registry, and to compare the rates of survivorship with those of cemented TKAs performed for primary knee osteoarthritis during the same 27-year period. Methods From the Finnish Arthroplasty Register, we obtained the data for 4713 patients undergoing UKAs for primary osteoarthritis (mean age, 63.5 years; minimum followup, 0 years; mean, 6.0 years; range, 0-24 years) who had surgical revision between 1985 and 2011. From this cohort, we calculated the Kaplan-Meier survivorship for revision performed for any reason and compared it with the survivorship of 83,511 patients (mean age, 69.5 years; minimum followup 0 years; mean, 6.4 years; range, 0-27 years) with TKAs treated for primary osteoarthritis during the same period. Data were adjusted for age and sex in a comparative analysis.

“…The reason behind the declining osteotomy figures may very well be the improved outcome of TKA in all patient groups during the last two decades. Additionally, UKAs have been performed in patients with less severe arthritis [8], which may have decreased the number of osteotomies performed.…”

Purpose Both tibial and femoral osteotomies have been used for the treatment of knee osteoarthritis (OA). Due to the clinical success of total knee arthroplasty (TKA) the current role and incidence of osteotomies remains unknown. The aim of this population-based study was to assess the incidence of osteotomies and compare it with that of knee arthroplasties. Methods From the Finnish National Hospital Discharge Register, we identified all patients, aged 18 years or more, who had undergone osteotomy for the treatment of knee OA between 1987 and 2008. The number of arthroplasties was extracted from the Arthroplasty Register. Results A total of 6,004 osteotomies were performed for 5,734 patients. The average osteotomy incidence has steadily decreased by 6.2%, and TKA incidence has increased by 9.8% annually. However, in patients aged less than 50 years the osteotomy incidence has increased by 1.4% annually. The decline of osteotomy incidence has been steeper in females than in males (9.0% vs. 3.6%), and during the last decade osteotomies were more commonly performed in male patients. ConclusionIncidence of osteotomies for the treatment of knee OA has decreased during last two decades. However, in patients aged less than 50 years the osteotomy incidence has slightly increased. In a comparison by gender, females are more likely to undergo arthoplasty than osteotomy, and it would therefore appear that the current use of osteotomies is predominantly reserved for the treatment of knee OA in relatively young males.
