Abstract The aim of this retrospective cohort study was to compare home physiotherapy with or without supervision of physiotherapist for assessing manipulation under anaesthesia after total knee arthroplasty. Methods A total of 900 patients (including 810 females and 90 males) who had undergone total knee arthroplasty were divided into group A (n = 300) and group B (n = 600). Patients in group A had home physiotherapy on their own after discharge from hospital. The physiotherapist did not visit them at home. Patients in group B received home physiotherapy under supervision of physiotherapist for 6 weeks after discharge from hospital. Patients’ age, range of motion of the knee, and forgotten joint score-12 were assessed. A p < 0.05 was considered statistically significant. Results In group A, the mean age was 69.1 ± 14.3 years (range: 58 to 82 years); in group B, the mean age was 66.5 ± 15.7 years (range: 56 to 83 years) (p > 0.05). Preoperatively, the mean range of motion of the knee in group A and B was 95.8° ± 18.1° and 95.4° ± 17.8°, respectively (p > 0.05). The mean forgotten joint score-12 of group A and B were 11.90 ± 11.3 and 11.72 ± 12.1 (p > 0.05), respectively. Six weeks after total knee arthroplasty, the mean ROM of the knee in group A and B was 109.7° ± 22.3° and 121° ± 21.5°, respectively (p < 0.05). The mean postoperative forgotten joint score-12 of the group A and B was 24.5 ± 16.4 and 25.6 ± 17.4, respectively (p > 0.05). The rate of manipulation under anaesthesia was 3% in group A and 0.2% in group B (p < 0.05). Conclusion After total knee arthroplasty, frequent physiotherapist’s instruction helps the patients improve knee exercises and therefore decrease the risk of revision surgery. The home physiotherapy under supervision of physiotherapist lowers the rate of manipulation under anaesthesia. Level of evidence Therapeutic study, Level IIa.

Background. With the development of three-dimensional printing (3DP) technology, the patient-specific instrumentation (PSI) has been widely applied in total knee arthroplasty (TKA). The purpose of this study was to compare the gait parameters of patients with 3DP personalized guide-assisted and standard TKA. Methods. Retrospective analysis of the advanced knee OA cases in our hospital between June 2017 and June 2018 was conducted. 30 cases received 3DP personalized guide-assisted TKA (group A), and 60 patients who underwent standard TKA during the same period were in group B and group C according to the computed tomography (CT) measurement results, each with 30 cases. Hip–knee–ankle angle (HKA), patella transverse axis-femoral transepicondylar axis angle (PFA), and gait parameters were statistically analyzed. The function was assessed by Hospital for Specific Surgery (HSS) and Knee Society Score (KSS). Results. The mean follow-up period was 12.3 months in the three groups. The knee max flexion angle at the swing phase of group A was larger than group B and group C (P<0.05), there was no statistically significant difference in other gait parameters. The mean PFA of group A was smaller than that of group B and group C (P<0.05). While, the HKA, HSS, and KSS scores of three groups showed no significant difference. Conclusion. 3DP personalized guide technology could improve the gait parameters after surgery, specifically reflected in the knee max flexion angle at the swing phase. It could also assist in the reconstruction of more accurate patellar tracking and rotational alignment in TKA, avoiding the occurrence of insufficient or excessive extorsion.

Acute pain is the most common complication after total knee arthroplasty(TKA) causing delayed mobilization and increased demands of morphine, leading to higher operative cost. Generally opioids and NSAIDs are used but the adverse effects limit their use. So a non-opioid agent like pregabalin is often recommended. Pregabalin can significantly improve pain scores, physical functions, satisfaction and reducing chronic neuropathic pain and the requirement of other analgesics in patient undergoing TKA. Patients received either standard analgesics as per the existing hospital policy (group A) or pregabalin added to the standard analgesics(group B). Pregabalin(75mg) was given as one capsule, the last night before the surgery and continued one capsule twice a day until end of postoperative day (POD)14 and one capsule at bedtime POD15, POD16. The group B showed significant reduction in pain score after 2 weeks of the surgery. It was 3.20±1.03 in group A and 2.48±0.77 in group B. The mean comparison of satisfaction level in group A and group B was found to be 7.80±0.96 and 9.52±1.04 respectively. The mean comparison of incidence of neuropathic pain in group A and group B was found to be 6.70±4.01 and 4.24±4.14 respectively. Our study concluded that pregabalin is effective in reducing pain after 2 weeks post TKA, and incidence of neuropathic pain. Increased patient satisfaction level and the quality of life of patients were observed in pregabalin treated group.

AbstractThe posterior tibial slope (PTS) is usually adjusted by less than 5 degrees, without considering its individual difference, during posterior cruciate-substituting (PS) total knee arthroplasty (TKA). The effect of these individual changes of PTS would be important because clinical results depending on postoperative PTS were reported conflictingly. We investigated the effect of the change in PTS on the postoperative range of motion (ROM) and clinical scores after PS TKA. We retrospectively reviewed 164 knees from 107 patients who underwent PS TKA with a 2-year follow-up. We analyzed the preoperative and postoperative PTS, ROM, visual analog scale pain scale, Western Ontario and McMaster University Index (WOMAC), Hospital for Special Surgery Knee Score, Knee Society Score, and Forgotten Joint Score (FJS). The association of the absolute change in PTS with ROM and clinical scores was analyzed using correlation analysis and multiple regression analysis. As a result, the mean PTS and mean ROM changed from 9.6 ±  3.4 and 120.1 ±  15.4 degrees preoperatively to 2.0 ±  1.3 and 128.4 ±  9.3 degrees postoperatively, and the mean PTS change was 7.6 ±  3.5 degrees. The PTS change had no statistically significant association with the postoperative ROM and clinical scoring systems, although it did have a weak positive correlation with WOMAC function, No 10 (difficulty in rising from sitting) (correlation coefficient = 0.342, p = 0.041), and moderate positive correlation with the FJS, No. 6 (awareness when climbing stairs) (correlation coefficient = 0.470, p = 0.001). The authors concluded that the amount of change in PTS did not affect the postoperative ROM and clinical scores, although proximal tibial resection with a constant target of PTS resulted in individually different changes in the PTS after PS TKA,

Abstract Background To explore whether previous arthroscopic knee surgery affects future total knee arthroplasty (TKA) results or not. Methods A total of 56 patients with the previous arthroscopic treatment on one knee underwent subsequent bilateral total knee arthroplasty in our hospital from September 2012 to July 2018. Data on each patient were collected in regards to changes in postoperative clinical and functional scores, various other scores, as well as postoperative functional recovery and complications. We defined the knees with a previous arthroscopic history as group A, and the counter side as group B. The Knee Society clinical score, functional scores, range of motion (ROM), finger joint size (FJS), visual analogue scale (VAS) scores were assessed before and after surgery. Using the Kolmogorov-Smirnov Test to test the normality of continuous variables, and the chi-square test to compare the rate of reoperation and complications between two groups. For all statistical comparisons, P < 0.05 was considered significant. Results There were no statistically significance differences found in postoperative Knee Society clinical scores and functional scores between group A and group B, as well as in ROM, FJS, VAS scores and local complications. Conclusion There were no statistically significant differences found in postoperative functional recovery and complications in patients, who underwent total knee arthroplasty with previous knee arthroscopy.

Purpose: Evaluate the reliability of the early functional recovery and postoperative pain control using adductor canal block (ACB) compared with that using femoral nerve block (FNB) in patients undergoing total knee replacement (TKR). Patients and Methods: A total of 80 patients scheduled for TKR were randomly and blindly distributed into two groups (40 patients each). Group A received ACB and group F received FNB. The early quadriceps strength, range of motion and pain control were assessed after surgery during the first 48[Formula: see text]h. Results: Patients in group F had significantly less quadriceps power postoperatively than those in group A. There were no significant differences between the two studied groups as regard ambulation, range of motion and pain estimation. Conclusion: Since both blocks have comparable analgesic effect and opioid consumption rates, the increased quadriceps muscle strength and ability to ambulate on the first postoperative day is the driving factor in selecting the ACB. With the findings discussed in our study and in literature, an ACB is a viable option in place of a FNB in patients undergoing a total knee arthroplasty. Additional large participant randomized controlled studies should be conducted to further discover the benefits of an ACB in patients undergoing a total knee arthroplasty.

Abstract Background To assess the efficacy and safety of intravenous and subsequent long-term oral tranexamic acid (TXA) following total knee arthroplasty (TKA) without a tourniquet. Methods In this double-blinded trial, 118 patients undergoing primary TKA were randomized into two groups: the patients in group A received intravenous TXA at 20-mg/kg 10 min before the surgery and 3 h postoperatively, and then oral 1 g TXA from postoperative day (POD) 1 to POD 14, and the patients in group B received intravenous TXA at 20-mg/kg 10 min before surgery and 3 h postoperatively, and then oral 1 g placebo from postoperative day (POD) 1 to POD 14. The primary outcome was total blood loss. Secondary outcomes included ecchymosis area and morbidity, postoperative transfusion, postoperative laboratory values, postoperative knee function and length of hospital stay. Complications, and patient satisfaction were also recorded. Results The mean total blood loss was lower in Group A than in Group B (671.7 ml vs 915.8 ml, P = 0.001). There was no significant difference in the transfusion rate between the two groups. Group A had a higher hemoglobin than Group B on POD 3 (106.0 g/L vs 99.7 g/L, P = 0.001). However, no significant difference was found for Hb or hematocrit on POD 1 or POD 14 between the two groups. Patients in Group A had less ecchymosis morbidity (7 vs 38, P = 0.001), smaller ecchymosis area (1.6 vs 3.0, P = 0.001) than Group B. The blood coagulation level as measured by fibrinolysis (D-Dimer) was lower in Group A than in Group B on POD 1 and POD 3 (4.6 mg/L vs. 8.4 mg/L, respectively, P = 0.001; 1.5 mg/L vs. 3.3 mg/L, respectively, P = 0.001). However, there was no significant difference on POD 14, and the fibrin degradation products showed the same trend. Patients in Group A had less swelling than those in Group B on POD 3 and POD 14. The circumference of the knee was 43.1 cm vs. 46.1 cm (POD 3, P = 0.001) and 41.4 cm vs. 44.9 cm (POD 14, P = 0.001) in Group A vs Group B, respectively. Nevertheless, the circumference of the knee in the two groups was similar on POD 1 and POD 3 M. No significant differences were identified in knee function, pain score, or hospital stay. No significant differences were identified in thromboembolic complications, infection, hematoma, wound healing and patients satisfaction between the two groups. Conclusion Intravenous and subsequent long-term oral TXA produced less blood loss and less swelling and ecchymosis compared with short-term TXA without increasing the risk of complications. Trial registration The trial was registered in the Chinese Clinical Trial Registry (ChiCTR-IPR-17012264).

Abstract Objective: In this prospective, randomized, controlled trial we sought to evaluate the effectiveness of acute normovolemic hemodilution (ANH) in terms of decreasing the need for allogeneic transfusion after conventional unilateral total knee arthroplasty (TKA). Summary of Background Data: TKA is often performed with an occlusive tourniquet, and thus, it could be considered ideally suited for ANH, because the chief benefit of ANH is red blood cell loss reduction and the shedding of whole blood perioperatively at lower hematocrit levels. Methods: Between January 2012 and May 2012, 40 consecutive patients scheduled to undergo elective, primary, cemented, unilateral TKA for knee osteoarthritis were enrolled. Patients were randomized to either a study (ANH) group (n=20) (Group A) or a control group (n=20) (Group B). Unit of allogeneic blood transfused was considered the primary outcomes. Results : In the ANH group, less allogeneic blood transfusion (6 units in Group A vs 15 units in Group B) was required after operation. Six patients, who required a transfusion in Group A received 1 unit of allogeneic blood. In contrast, 6 of 9 patients, who required transfusion in Group B, received at least 2 units of allogeneic blood (p&lt;0.05). There was no complication related to the methods of the protocol. Conclusions: ANH is likely to reduce postoperative allogeneic transfusion requirement in patients undergoing unilateral TKA. However, adjunctive strategies are required to further reduce allogeneic blood transfusion requirements.

Abstract Purpose: We hypothesized that patellar positioning during minimally invasive total knee arthroplasty (MIS-TKA) would affect soft tissue balance and postoperative outcome.Methods: From December 2018 to February 2019, 55 patients receiving primary MIS-TKA were enrolled. The gap-balance technique was used, with patients randomly assigned to undergo osteotomy and balance of soft tissue with the patella reduced (group A; n = 27) or with the patella subluxated (group B; n = 28). The soft tissue balance achieved with the patella reduced and subluxated were compared. Femoral prosthesis rotation, mechanical femoral axis–to–tibial axis angle, Knee Society Score (KSS), pain score, and range of flexion were compared between the groups. Follow-up was for 6 months.Results: The flexion gap and the varus angle were significantly greater after patella reduction than before reduction, but the extension joint gap and varus angle were comparable before and after patella reduction. The femoral prosthesis tended to be internally rotated in group B. Range of flexion was better in the group A than in group B at 1 month after surgery, but the differences were not significant at 3 and 6 months. KSS and pain score were comparable between the groups after surgery.Conclusion: During MIS-TKA, as far as possible, soft tissue balance should be achieved with the patella reduced; otherwise, the femoral prosthesis may be installed more internally and, after patella reduction, the flexion gap and varus would increase.

Background: We evaluated the accuracy of a sagittal alignment of tibial component in total knee arthroplasty (TKA) with the sagittal reference line using the preoperative radiograph. Methods: We evaluated 151 patients who underwent primary TKA with posterior cruciate substituting type implant. For 75 patients, the sagittal reference line using preoperative radiograph (group A) was used, while for 76 patients the sagittal reference using intraoperative fibular shaft line (group B) was used. The parallel line (line S) to the anatomical axis of the tibia in the lateral plain radiograph was used as the sagittal reference. The distance from line S to proximal tibia cutting area and to skin surface 20 cm distal to the cutting area was measured in preoperative radiographs. Next, the distance to the extramedullary guide rod was applied intraoperatively, reflecting the results. The intraoperative fibular shaft line was determined using the connecting line between the tip of fibular head and the lateral malleolus. The postoperative tibial component slope angle and the difference to the target slope angle were compared. Results: The difference to the target angle was 1.8 ± 1.3° in group A, whereas the difference was 2.5 ± 1.4° in group B ( p = 0.04). The patients with difference within 3° to the target angle were 78.7% in group A and 61.8% in group B ( p = 0.024). Conclusion: The sagittal reference line using the preoperative lateral radiograph was helpful as a reference guide for the tibial slope in TKA.
