Abstract Introduction: Knee osteoarthritis is one of the most common causes of joint pain and destruction in people over forty years old. This research has investigated the effect of using a drain on Fe, TIBC, and Hb levels in knee joint replacement surgery in a 6-months period, as a prospective cohort study.
Materials & Methods: All patients who were candidates for knee joint replacement in one hospital, were included in a prospective study. The grouping of patients included those who had post-operative drain (45 patients)and the ones with no drain (45 cases). and the control group were those who did not undergo drainage after the intervention. Fe, TIBC, and Hb levels were compared 3 months post-surgery.
Results & Discussion: A total of 21 men and 69 women were in the case and control groups. The average age in the case group was 67.67 years and in the control group was 68.96. The confounding variables considered in this study, including age, gender, and underlying diseases (including hypertension, diabetes, and hypothyroidism) were examined in both groups, and there was no significant difference between the group with and without a drain; Therefore, the difference between the two groups in this study was caused by the blood indices. However, the ferritin level of preoperative patients was different in the two groups. The most important blood index that was significant in all analyzes was hemoglobin changes before and after the operation. Also, significant changes in TIBC were present.
Conclusion: Drain use in knee replacement surgery results in less HB drop. Good blood loss strajedy can lower the drop in TIBC in 3 months follow-up.

Abstract Background: The purpose of this study is to investigate the results of surgical treatment for hallux rigidus using the Weil osteotomy method in grade III patients with this disease.
Methods: This quasi-experimental study involved a single-group intervention "before and after" the surgery. The research population consisted of patients with grade 3 hallux rigidus. The data collection tool used in this study was a checklist based on clinical examinations that evaluated joint movement in both plantar and lateral directions, as well as the Visual Analog Scale (VAS) to measure pain. The range of motion and pain level of the metatarsophalangeal (MTP) join were investigated and recorded before the operation and 1, 3, and 6 months after the operation. All this information was entered into SPSS software version 26.
Results: The study groups included 8 (22.9%) male and 27 (77.1%) female patients, with an average age of 77.1 ± 12.17 years. The amount of pain decreased significantly (P=0.00) at the one-month and three-month follow-ups after the intervention, and the amount of passive movement of the joint in the plantar directions significantly increased from one month to three months after the intervention (P=0.00). 17 patients (48.6%) took up to two weeks after surgery, 10 patients (28.6%) between two to four weeks, and 8 patients (22.9%) more than one month to recover the mobility. The average joint space of the patients after the operation in plain radiography was 3.6 ± 0.46.
Conclusion: : The Weil osteotomy surgery in hallux rigidus patients showed a significant decrease in pain level, and also a significant increase in joint motion and improvement in the average joint space in short term.
