“…Although the literature suggests high survival rates for conventional TKAs [36], patients often have major concerns regarding postoperative pain and length of recovery [7,24]. Surgeons have attempted to achieve additional improvement in postoperative outcomes by reducing the size and number of incisions [4,28,41].…”

Background Concerns have been raised regarding minimally invasive surgery (MIS) and its possible effect on postoperative functional recovery, complications, and survival rate after TKA. Questions/purposes We specifically asked whether MIS TKA would be associated with (1) increased operative time, (2) reduced blood loss, (3) shortened hospital stay, (4) faster recovery of ROM, (5) higher knee scores, (6) inferior component positioning, and (7) increased complications. Methods We performed a systematic literature search of randomized controlled trials between minimally invasive and standard approaches in TKA that compared operative time, blood loss, ROM, knee scores, component positioning, and complications. We conducted a systematic review and meta-analysis of 13 trials published from 2007 to 2009 of MIS versus standard TKA.

“…Greater than 3°varus or valgus mal-alignment in total knee replacement (TKR) can result in higher failure rates whilst correct alignment has been associated with improved clinical outcome [7,11,19]. Several authors have shown that traditional hand-guided alignment systems can produce potential errors in the bone cutting process even when used by experienced surgeons [1,2,14,[16][17][18]21]. Recently, Manley et al showed that patients undergoing TKR in low volume hospitals (1-25 procedures/year) had a higher risk of early revision at five and eight years compared with those performed in the highest volume hospitals (>200 procedures/year) [15].…”

Computer-assisted total knee replacement (TKR) has been shown to improve radiographic alignment. Continuous feedback from the navigation system allows accurate adjustment of the bone cuts, thus reducing errors. The aim of this study was to determine the impact of experience both with computer navigation and knee replacement surgery on the frequency of errors in intraoperative bone cuts and implant alignment. Three homogeneous patient groups undergoing computer assisted TKR were included in the study. Each group was treated by one of three surgeons with varying experience in computer-aided and knee replacement surgery. Surgeon A had extensive experience in knee replacement and computer-assisted surgery. Surgeon B was an experienced knee replacement surgeon. A general orthopaedic surgeon with limited knee replacement surgery experience performed all surgeries in group C. The cutting errors and the number of re-cuts were determined intraoperatively. The complications and mean surgical time were collected for each group. The postoperative frontal femoral component angle, frontal tibial component angle, hip-knee-ankle angle and component slopes were evaluated. The results showed that the number of cutting errors were lowest for TKR performed by the surgeon with experience in navigation. This difference was statistically significant when compared to the general orthopaedic surgeon. A statistically significant superior result was achieved in final mechanical axis alignment for the surgeon experienced in computerguided surgery compared to the other two groups (179.3°c ompared to 178.9°and 178.1°). However, the total number of outliers was similar, with no statistically significant differences among the three surgeons. Experience with navigation significantly reduced the surgical time.

“…Long-term clinical success of various designs of total knee arthroplasty have been widely published in the literature [1][2][3][4][5]. However, some concerns remain in relation to femoropatellar symptoms, anterior knee pain, patellar clunk, and backside wear [6][7][8].…”

Purpose Our goal was to evaluate the five-year follow-up results of the Scorpio single radius total knee arthroplasty. Method We performed a retrospective study based upon a multicentre database to evaluate the minimum five-year follow-up clinical and radiological results of 747 patients (831 knees) who underwent primary Scorpio single radius total knee arthroplasty. Results The mean age of the patients was 71.9 years. At a minimal five-year follow-up, 141 patients were lost to follow-up, 83 patients had died, eight patients had undergone revision of a component, and the remaining 589 patients (602 knees) had a complete clinical and radiological evaluation after a median of six years (range, 5-8). The mean clinical component of the knee score was 92.2 points, and the mean functional component of the knee score was 76.9 points. At last follow-up, 530 of the 602 knees were rated as excellent or good. Only four knees developed patellar complications requiring revision. The survival rate at six years was 95.2%±1.9% and 98.3%±0.6 with revision for any reason and revision for mechanical failure as the end point, respectively. Conclusion This medium-term study indicates favourable clinical and radiological results for this single flexionextension radius design arthroplasty, with a low complication rate on the patellar side.
