ABSTRACT
Introduction Total knee arthroplasty is the standard of care treatment for advanced knee osteoarthritis. However, patients frequently continue to have pain and disability after surgery, with one of the most common reasons being a bone-implant mismatch. Notably, there is a significant difference reported in proximal tibia morphometry between Asian and Caucasian populations, and the currently available implants do not account for the anthropometric variations observed across ethnicities. We aimed to evaluate the proximal tibia anthropometry in a Pakistani population. Materials and methods A study was conducted at The Indus Hospital, Karachi Campus, from August 2019 to July 2020. All consecutive patients fulfilling the eligibility criteria and undergoing knee replacement surgery were included in the study. Baseline characteristics and anthropometry of proximal tibia were recorded on a pre-designed proforma. Statistical analysis was done using SPSS version 24. Results A total of 30 patients were enrolled in this study, which included 17 females (56.7%) and 13 males (43.3%). The mean age was 61.6± 7.9 years and the BMI was 33±5.7 kg/m2. There was a significant difference found in the anteroposterior and mediolateral dimensions in both genders. A significant association was noted with body mass index (p-value 0.01) and occupation (p-value=0.02). Conclusion The results indicated that the anatomical profile of the proximal tibia in the Pakistani population is distinct, thus stressing the fact that it requires developing prostheses specifically tailored to this population's sizing requirements.
ABSTRACT
Introduction Hip fracture surgeries constitute a large portion of orthopedic surgeries, and infective complications are one of the most severe and devastating sequels following fixations or replacements. Preoperative antibiotic prophylaxis is an important means to control SSI. Thus, we set out to assess the impact of a single dose versus three doses of antibiotics on surgical site infections in patients undergoing hip surgery. Materials and methods A randomized controlled trial was conducted at the Department of Orthopaedics, The Indus Hospital, Karachi, Pakistan. All patients admitted for hip fracture surgery who met the inclusion criteria were enrolled and divided into two groups. One group (Group A) was given a single dose of antibiotics preoperatively, and the other (Group B) was given three doses, one preoperatively and two postoperatively. Patients were assessed for wound condition and signs of infection. Data were entered and analyzed using SPSS version 21.0. The chi-square test was applied to assess the significant association between both the groups and SSI. A significant statistical association was noted when the P value was found to be <0.05. Results The study included 62 patients, with the majority of them being females (n=33; 53.2%). The mean age of the patients was 60.5±15.1 years. Only three (4.8%) patients developed SSI. No statistically significant association was detected between surgical site infections and the two antibiotic regimens being administered after controlling for the confounders. Conclusion There was no statistical relationship between surgical site infections with a single dose versus three doses of antibiotics in patients undergoing hip surgery.
