Abstract
Background Total hip arthroplasty (THA) is the most successful orthopedic elective surgical procedure for end-stage hip arthritis. THA is linked with significant blood loss, ranging from 1,188 to 1,651 mL, and a transfusion rate of 16-37%, which frequently results in postoperative blood transfusions. Postoperative blood transfusions can be avoided by using autologous blood transfusion, intraoperative blood saving, local anesthetic, hypotensive anesthesia, and antifibrinolytic medications such as tranexamic acid (TXA) administration. Methodology A double-blinded, placebo-controlled, randomized, controlled study was conducted with three prospective groups to investigate the efficacy of topical and systemic routes of a single intraoperative dose (1.5 g) of TXA. Patients were recruited from our center between October 2021 to March 2022 who were undergoing primary total hip replacement. Estimated blood loss was calculated and compared in groups, and a p-value of <0.05 was taken as significant. Results A total of 60 patients were recruited in our study. Estimated blood loss was similar in both treatment groups, 816.8 ± 219.9 mL in the systemic TXA group and 775.5 ± 107.2 mL in the topical TXA group. The placebo group had 1,066.3 ± 150.4 mL estimated blood loss, which was significantly higher compared to the treatment groups. Conclusions Administration of TXA (1.5 g) significantly lowers blood loss without increasing problems, which can eliminate concerns about intravenous TXA use. TXA reduces blood loss by 270 mL on average.

Abstract
PURPOSE A tourniquet is routinely used during total knee arthroplasty (TKA) to reduce intra-operative hemorrhage, though surgery without a tourniquet is becoming popular. To address concerns about the effect of blood at cement interfaces on long-term implant stability, we conducted a systematic review among patients undergoing total knee arthroplasty to determine if TKA with a tourniquet, compared to TKA without a tourniquet or with reduced tourniquet duration, is associated with better mid-term and long-term implant stability. METHODS A literature search was conducted without language restriction in PubMed, Cochrane database and Web of Science from conception to 17th March, 2021. Prospective cohorts, randomized and observational, that compared tourniquet use with a control group, followed patients for 3 months or more and reported outcomes concerning implant stability, limb function, pain and inflammation. Article selection, quality assessment according to the Revised Cochrane risk assessment scale and Newcastle Ottawa Scale, and data extraction were conducted in duplicate. PROSPERO CRD42020179020. RESULTS The search yielded 4868 articles, from which 16 randomized controlled trials (RCT) and four prospective cohort studies, evaluating outcomes of 1884 knees, were included. Eleven RCTs were evaluated to be low overall risk of bias, five RCTs had some concerns and four cohort studies were good quality. Few studies showed benefits of tourniquet use in mid-term implant stability (1/6), pain (1/11) and limb inflammation (1/5), and long-term implant stability (1/1). One study reported a significantly improved range of motion (1/14) while another reported significantly reduced quadriceps strength (1/6) in the tourniquet group. The remaining studies reported non-significant effect of tourniquet use. CONCLUSION Although few studies indicated benefits of tourniquet use in mid-term pain, limb inflammation, implant loosening and function, and long-term implant loosening, the majority of studies report no significant advantage of tourniquet use in total knee arthroplasty.

Abstract
AIMS AND OBJECTIVES To measure the additional effect of platelet-rich plasma (PRP) on functional outcome of anterior cruciate ligament tear managed by augmenting anterior cruciate ligament (ACL) reconstruction with PRP. METHODS The present study was conducted on patients with ACL tear admitted in the department of orthopaedics, King George's Medical University, Lucknow wherein a total of 70 subjects were assigned into two groups of 35 patients each randomly, viz Group 1 in which the patients were treated by quadruple hamstring graft alone and Group 2 in which the patients were treated with augmented hamstring graft with PRP. The standardized anterior drawer test, Lachman's test, Lysholm knee score were quantified both preoperatively and postoperatively at different follow-ups and also tibial tunnel widening was measured postoperatively at different follow-ups. RESULT The present study had 70 patients with ACL tears. The mean age of patients in non-PRP groups was 29.71 ±2.99 years while that in the PRP group was 28.34±4.32 years. On comparing the improvement in grades at pre-op, immediate postop, 6 weeks, and 3 months follow-ups, there was no statistically significant difference between the two groups. The tibial tunnel widening also showed no significant difference between the two groups. CONCLUSION In our study, it was found that both the groups showed improvements in grades of anterior drawer test and Lachman's test postoperatively but the difference between both the groups was not significant. Similarly, while comparing the improvements in Lysholm knee score and tibial tunnel widening among both the groups, the difference was not significant. Follow up of 3 months was a limiting factor in our study. This technique needs further clinical evaluation to assess the long-term results.
