Although TKA surgeries have a high success rate, complications, failed surgeries, and patient dissatisfaction are unavoidable. This works follows a previous study, which showed that 2.6% of all primary to- tal hip arthroplasties in Denmark reported to the Danish Patient Compensation Association (DPCA), resulted in compensation; and half of these were approved. Purpose / Aim of Study: We examined the DPCA database to outline the frequency and financial burden of compensation claims after primary TKA in Denmark. Materials and Methods: This was a retrospective study of closed compensa- tion claims following TKA reported to DPCA between 1st of January 2005 and 31st of December 2017. The primary cause for claim was included. Findings / Results: There were 1,611 primary TKA claims out of 29,370 or- thopaedic cases reported (5.5%). This accounts for 2% of all TKAs performed in this period. The approval rate was 42%. The number of claims filed had in- creased with a peak in 2012, followed by a decrease. The total payout was DKK 145,269,621. The highest payouts were for infection (DKK 59,011,085), insufficient or incorrect treatment (DKK 32,371,468), nerve damage (DKK 19,831,988), and incorrect indication (DKK 9,069,492). Collectively, these four complications accounted for 83% of the total amount of payouts. Claims most likely to be filed were due to insufficient or incorrect treatment (29%), in- fection (23%), dissatisfaction with correct treatment (17%), and nerve damage (7%). However, those likely to result in payout were pressure ulcer with a payout success rate of 86%, followed by incorrect indication (82%), missed diagnosis (82%), and incorrect prosthesis or equipment (76%). Conclusions: 2% of all primary TKAs resulted in a compensation claim reported to DPCA with a 42% approval-rate. The majority of payouts were due to infec- tion, insufficient or incorrect treatment, nerve damage, and incorrect indication. Although DPCA manages claims for patients, the data can also provide beneficial feedback to arthroplasty surgeons with the aim of improving patient care. 83.
