The study was approved by the Bioethics Committee and the Hospital Quality Commission and with the signed informed consent of the patients. The patients included in the study were those who had been diagnosed with tricompartmental gonarthrosis of the knee and referred for TKA. 108 patients were randomly selected from the two groups: CG and IG. The patients selected for the IG were those who had undergone surgery on even days and those of the CG on odd days. The exclusion criteria were as follows: patients allergic to NSAIDS or local anaesthetics, those who refused or had contraindications to intradural regional anaesthesia and those patients with mental, psychiatric or neuromuscular degenerative diseases.</p><p id="par0030" class="elsevierStylePara elsevierViewall">Of the 108 patients, in the CG, two had to abandon the study due to the technical impossibility of administering intradural anaesthesia. In the IG another five patients abandoned the study: three of them due to the failure of implanting the catheter in the operating theatre and two due to possible allergy to NSAIDS. This meant that the elastomeric pump could not be used in the anaesthesia recovery room. One catheter fell to the floor in the operating theatre and was no longer sterile, another was burned with an electric scalpel and in a third patient, a trocar was incorrectly removed and consequently rejected (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>).</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><p id="par0035" class="elsevierStylePara elsevierViewall">The patients were operated on by the same group of orthopaedic surgeons and during the same period of time, which was between January and March 2016.

The result obtained in this work, with lower hospital stay, indicates that the use of the intraarticular catheter, and the postoperative analgesia is a highly appropriate technique for a rapid recovery system in knee arthroplasty.

A randomised study was carried out to this effect to compare postoperative pain, the use of analgesics, the functioning of the operated knee, the onset of walking, hospital stay duration and the appearance of complications immediately after surgery.</p><p id="par0120" class="elsevierStylePara elsevierViewall">Pain assessment was made on a verbal rating scale on the first and second postoperative day, on the assumption that the highest differences would be found, since after the first 48<span class="elsevierStyleHsp" style=""></span>h following surgery the effects of both analgesics would cease.<a class="elsevierStyleCrossRefs" href="#bib0160"><span class="elsevierStyleSup">9,14,15</span></a></p><p id="par0125" class="elsevierStylePara elsevierViewall">Although no other study used the same pain management protocols, similar studies compared periarticular injection with nerve blocks and showed outcomes similar to our study.

Carli et al.<a class="elsevierStyleCrossRef" href="#bib0200"><span class="elsevierStyleSup">17</span></a> compared local infiltration with femoral block and no significant differences were shown in pain intensity in repose or consumption of opioids after TKA.

In a transversal study carried out on a global scale, and by autonomous community out of the total primary arthroplasty of the hip (THA) and TKA reported by Allepuz et al.,<a class="elsevierStyleCrossRef" href="#bib0215"><span class="elsevierStyleSup">20</span></a> the median stay was 9 days for THA and 8 days for TKA. Brunenberg et al.<a class="elsevierStyleCrossRefs" href="#bib0210"><span class="elsevierStyleSup">19,21</span></a> studied the cost-effectiveness of patients who underwent TKA and ATC. Mean hospital stay of the patients who were treated later with physiotherapy was lower than that of patients who did not receive this treatment (the difference was 4.1 days in hip and 6.9 days in knee, with statistically significant differences).</p><p id="par0145" class="elsevierStylePara elsevierViewall">Several studies have shown that there is not a higher risk of infection when an intraarticular catheter is inserted up to 72<span class="elsevierStyleHsp" style=""></span>h,<a class="elsevierStyleCrossRefs" href="#bib0210"><span class="elsevierStyleSup">19,22</span></a> and they may even be used for the treatment of prosthetic infection in the hip and knee with antibiotic infusion.<a class="elsevierStyleCrossRef" href="#bib0230"><span class="elsevierStyleSup">23</span></a></p><p id="par0150" class="elsevierStylePara elsevierViewall">Our study had several limitations. We could not prevent the patients and the staff being aware of the analgesic treatment received, since the presence of both the intraarticular catheter and the epidural catheter made it clear to which study group they belonged.</p><p id="par0155" class="elsevierStylePara elsevierViewall">The patients were not operated on by the same surgeon, despite them all belonging to the same working team, and this was a limitation to the study. Moreover, for this study two different prosthesis models were used: PFC Sigma (Johnson & Johnson, Warsaw Ind.) and Advance Medial-Pivot (Wright Medical Technology, Arlington TN).</p><p id="par0160" class="elsevierStylePara elsevierViewall">After the outcome obtained with data analysis, we may say that the use of the intraarticular catheter in patients who undergo a total primary knee arthroplasty as postoperative analgesia is a valid and safe alternative, with improvement in immediate postoperative pain. This means a better range of movement in the operated knee, that the onset of walking is earlier, there is a reduction in the onset of the before-mentioned side effects, patient satisfaction improves and hospital stay is reduced.</p><p id="par0165" class="elsevierStylePara elsevierViewall">We therefore conclude that the use of the intraarticular catheter as a postoperative analgesic technique improves the outcomes compared with the use of the epidural catheter, and it is therefore an effective alternative in the treatment of postoperative pain after total knee arthroplasty.</p></span><span
