Purpose: Total knee arthroplasty (TKA) in syphilitic neuroarthropathy using earlier implant designs was associated with poorer outcomes. Literature on TKA for non-syphilitic neuroarthropathy using modern contemporary prosthesis is scarce. We aim to analyse the clinical and radiological outcomes of TKA in neuropathic joints.

Background: This study aims to systematically compare the efficacy of two distinct approaches that is limb occlusion pressure (LOP) and systolic blood pressure (SBP) in determining the optimal tourniquet pressure for primary total knee arthroplasty. The overarching goal is to identify the method that yields superior outcomes in minimizing post-operative thigh pain while simultaneously reducing complications in our patient population.

Methods: 311 patients scheduled for primary total knee replacement (TKR) were randomized in two groups.

The aim of this study was to compare the short term clinical and radiological outcomes of imageless robotic and conventional total knee arthroplasty (TKA) and to estimate the accuracy of the two techniques by analysing the outliers after TKA. We have evaluated 200 consecutive knees (158 patients), 100 knees undergoing robotic TKA, and 100 knees treated with conventional TKA. Demographic parameters like age, gender, body mass index, diagnosis and range of motion were obtained.

Common peroneal nerve (CPN) injury is a serious complication following total knee arthroplasty (TKA). We aim to report four patients (five knees) who underwent prophylactic peroneal nerve decompression for severe rigid valgus deformity with or without associated fixed flexion deformity that was not correctable under anaesthesia. The preoperative deformity of 31.

Background: Wound closure in joint replacement surgeries is crucial for postoperative rehabilitation. Despite substantial advances in total knee arthroplasty (TKA), no guidelines/recommendation or consensus practice statement available internationally or nationally around the optimal method of wound closure. The study aimed to develop evidence-based consensus on current practices, and proposed adoption of advanced wound closure initiatives.

Purpose: Our study aims to find the role of lateral retinacular release (LRR) on realigning the patella in knees with maltracking during primary total knee arthroplasty. We also compared the patellar morphological factors between the varus and valgus knees on predicting the need for LRR.

Methods: We have retrospectively analyzed the incidence of LRR in consecutive 152 primary TKA (124 patients) from May 2018 to December 2018.

Purpose: The aim of our study was to determine the surgical outcomes of patients who underwent lateral femoral sliding osteotomy (LFSO) with total knee arthroplasty (TKA) for Ranawat's type 2 fixed valgus deformity.

Methods: The consecutive patients who underwent primary TKA with posterior-stabilized implant and LFSO for fixed valgus deformity were reviewed. The radiological parameters analyzed were pre- and postoperative hip-knee-ankle (HKA) angle and tibio-femoral angle in varus-valgus stress views.

Aim: Our study aims to analyze the outcomes of conversion total hip replacement (THR) done for failed hemiarthroplasty.

Patients And Methods: We retrospectively analyzed 104 consecutive patients who underwent conversion THR for failed hemiarthroplasty between January 2012 and December 2018. The patient's records were analyzed for demographic information, index surgery details, preoperative functional status, and perioperative complications.

Background: A survey of the American Association of Hip and Knee Surgeons (AAHKS) reported that 95% of respondents attempted to modify risk factors prior to arthroplasty. This study investigated Indian arthroplasty surgeons' approach to patients who have modifiable risk factors.

Methods: The AAHKS survey tool was adapted for Indian surgeons and distributed to the membership of the Indian Society of Hip and Knee Surgeons and Indian Arthroplasty Association via a Survey Monkey.

Purpose: We aim to compare the outcome of culture-positive (CP PJI) and culture-negative (CN PJI) acute knee prosthetic joint infection (PJI) following debridement, antibiotics and implant retention (DAIR) with polyethylene insert exchange. We also aim to analyze the factors associated with the successful outcome of DAIR and the influence of failed DAIR on the outcome of subsequent two-stage revision arthroplasty.

Methods: We performed a retrospective review of 36 consecutive patients who underwent DAIR for acute PJI between January 2013 and January 2018.

Background: We aim to report the consecutive patients diagnosed with osteonecrosis of femoral head (ONFH) following recovery from COVID-19 disease and elucidate the unique features of ONFH associated with COVID-19.

Methods: Consecutive 22 patients (39 hips) recovered from COVID-19 and presented with ONFH from November 2020 to October 2021 were included. All the patients received corticosteroids as a supportive treatment during COVID-19.

Background: Acetabular reconstruction in complex primary and revision total hip arthroplasty (THA) with bone loss poses a great challenge. We aim to evaluate the medium-term clinical and radiological outcome of reconstruction rings used in these difficult situations.

Methods: We retrospectively reviewed a consecutive series of acetabular reconstructions with Muller ring or Bursh-Schneider cage from January 2009 to December 2016.

Purpose: The aim of our study is to compare the efficacy of adductor canal block (ACB), periarticular local infiltration (PLI) and both combined (ACB + PLI) in multimodal pain management after TKA.

Methods: This is a prospective, randomized controlled double-blinded study undergoing primary unilateral TKA. They were randomized into three groups with fifty patients in each group: ACB alone (30 ml of 0.

Background: The purpose of this study is (1) to find the clinical and radiological outcome of intraoperative bony avulsion of medial collateral ligament (MCL) treated with screw and washer construct and (2) to predict the preoperative factors which may contribute to the avulsion-type MCL injury during primary total knee arthroplasty (TKA).

Methods: Intraoperative MCL avulsion injury occurred in 46 (0.8%) of the 4916 consecutive primary TKA from January 2011 to December 2015.

Background: The aim of this article is to study the correlation between preoperative pain sensitivity and postoperative pain and analgesic requirements for patients undergoing primary total knee arthroplasty.

Methods: Between December 2018 and April 2019, the pain sensitivity of 178 consecutive patients undergoing primary total knee arthroplasty was assessed preoperatively with a digital algometer. The patients reported the VAS (visual analog scale) score at 3 instances of needle prick (phlebotomy, glucometer blood sugar, intradermal antibiotic test dose), during the range of movements and completed the Depression Anxiety Stress Scale score.

Purpose: Tibial bowing in valgus knees with arthritis can lead to component malplacement during total knee arthroplasty (TKA). Incidence of valgus knees with medial tibial bowing, its effect on tibial component placement during primary TKA and methods to improve accuracy of the component placement were studied.

Background: Proper patellar tracking is essential for well-functioning total knee arthroplasty (TKA). Besides implanting components in the correct position and rotation, balancing parapatellar soft tissues is also important in aiding normal patellar tracking. Patellar maltracking during TKA can be improved by lateral retinacular release (LRR).
