Polmacoxib: A Review of the Newer Non-steroidal Anti-inflammatory Drug in Osteoarthritis.

Osteoarthritis represents a huge socioeconomic burden and has a significant impact on daily life and productivity. Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in the management of osteoarthritis to curb inflammation, pain, and stiffness and improve physical function. However, due to the various side effects, most healthcare professionals avoid using NSAIDs for a long period. Nonselective cyclooxygenase (COX) inhibitors and cyclooxygenase-1 (COX-1) inhibitors are associated with increased gastrointestinal adverse effects due to the inhibition of prostaglandins, which are responsible for protecting the gastric mucosa. Cyclooxygenase-2 (COX-2) inhibitors are associated with an increased incidence of adverse cardiovascular effects due to their COX-2 inhibitory activity in the circulatory system. Therefore, there is a need for a newer NSAID that has a better safety profile to be used in osteoarthritis. Polmacoxib is a new, orally active, first-in-class NSAID that is a dual inhibitor of COX-2 and carbonic anhydrase (CA). The dual mode of action exhibited by polmacoxib is expected to minimize adverse cardiovascular effects while achieving maximum effectiveness in inflamed osteoarthritic joints. This article aims to review the pharmacological properties, clinical efficacy, and safety data of polmacoxib in osteoarthritis.

Prophylaxis for preventing venous thromboembolism in knee arthroscopy and soft tissue reconstruction: consensus statements from an international panel of experts.

PURPOSE: There is a lack of consensus regarding need for Venous Thrombo Embolism (VTE) prophylaxis following arthroscopic knee surgery and open soft tissue knee reconstruction. Clear cut guidelines like ones for trauma surgery and arthroplasty do not exist and the published literature is limited to case reports with a few society guidelines. Given this lack of consensus, we conducted a modified Delphi questionnaire of international experts to provide recommendations on this topic. METHODS: The consensus statements were generated using an anonymised 3 round modified Delphi questionnaire, sent to an international panel of 38 knee surgeons, with an 80% agreement being set as the limit for consensus. The responses were analysed using descriptive statistics with measures like mode, median and box plots. Feedback was provided to all panelists based on responses from the previous rounds to help generate the consensus. RESULTS: Six consensus statements were generated after the three rounds of Delphi. Patient factors, prolonged surgery duration and family history of thrombogenic events emerged as the main points to be taken into consideration for prophylaxis. CONCLUSION: It was established through this study, that there exists a select group of patients undergoing arthroscopic surgery that justify the usage of VTE prophylaxis. The expert responses to most of the questions in different scenarios favoured usage of VTE prophylaxis based on patient factors like advanced age, past history of VTE, smoking, oral contraceptive use etc. LEVEL OF EVIDENCE: Level V.

Management Guidelines for Infection After ACL Reconstruction: Expert Opinion Statement Based on the Modified Delphi Survey of Indian Arthroscopy Surgeons.

AIM: Infection after anterior cruciate ligament (ACL) reconstruction, though rare, is a potentially devastating complication and the evidence-based recommendation on the various topics in its management is limited. The purpose of this study was to develop recommendations for the prevention and management of infections in ACL reconstruction surgery by performing a structured expert consensus survey using Delphi methodology. MATERIALS AND METHODS: 22 topics of relevance in the prevention and management of infection following ACL reconstruction were chosen from an extensive literature review. 30 panelists were requested to respond to a three-round survey, with feedback, to develop a consensus statement on the topics. RESULTS: Consensus statements could be prepared in eleven out of twenty-two topics including: the graft is retained at the first arthroscopic debridement, the graft is removed when repeated debridement are needed, and revision ACL reconstruction is needed only if the patient develops instability. Concurrence could be obtained in the topics including: longer duration of antibiotics is needed in immunocompromised patients, soaking graft in antibiotic solution reduces infection risk, and knee swelling without warmth does not suggest infection. CONCLUSIONS: A proper skin preparation, a longer course of antibiotics in immunocompromised patients, and soaking the graft in antibiotics reduces the risk of infection. In case of infection, a healthy-looking graft must be retained at the first debridement and if the graft must be removed, revision ACL reconstruction is advised only if the patient develops instability.

Viscosupplementation for Management of Knee Osteoarthritis from an Indian Perspective: An Expert Consensus Report.

INTRODUCTION: Knee osteoarthritis (OA) is a progressive degenerative condition and is a significant contributor toward physical disability in the aging population. The current treatment modalities for this condition focus on joint preservation with alleviation of symptoms. Intra-articular hyaluronic acid (IAHA) injections have emerged as the promising mainstay of nonsurgical treatment of OA, especially in patients with mild-to-moderate OA and in certain subgroups of severe OA with comorbidities or with poor response to first-line therapy. The absence of standard guidelines or recommendations for the use of IAHA in India has led to vast variations in the usage of IAHA among practitioners. Hence, this consensus-based document aims to address the issue and establish simplified and easily implemented recommendations on the use of IAHA. METHODS: A group of 78 expert orthopedic surgeons discussed in detail the evidence on appropriate criteria for diagnosis, patient selection, and follow-up evaluation for knee OA at two national meetings. In subsequently held regional meetings, key discussion points and clinical experience-based answers were translated into a questionnaire to develop the final expert consensus-based statements for the use of IAHA in patients with knee OA. RESULTS: Various consensus statements were obtained on the basis of scientific evidence obtained from PubMed, Cochrane-indexed database, and guidelines related to viscosupplementation and knee OA as well as the experts' clinical experience. This document was drafted, reviewed, validated, and modified by the expert panel until a final agreement was reached. CONCLUSION: In this pioneering attempt, the document lays down structured, expert consensus-based statements to guide and align practitioners on the appropriate use of IAHA in the Indian setting.
