Abstract
Background: The effectivity of applying antiseptics in preparation of the operative site on the reduction of post-operative infections is not quite clear and controversies exist about the best method for doing this. The aim of this study is to compare the traditional two-stage method of first, washing the site with povidone iodine scrub and then painting with aqueous povidone iodine with the method of washing the site only with povidone iodine scrub. Materials and Methods: In this retrospective study, patients who had been under knee arthroscopy in 2 separate hospitals by the same surgeon were compared with regard to post operative infection. In one hospital, the operative site was only washed with povidone iodine scrub, while in the other hospital this same procedure was followed by painting with aqueous povidone iodine. The primary goal of this study was to identify the patients who had manifested clinical and laboratory signs of superficial or deep infection or septic arthritis one month postoperatively. Results: A total 300 patients were studied in two equal groups. All the patients had only been under diagnostic or curative non-bony operations. No superficial or deep infection or septic arthritis were seen in any of the patients in the two groups. Conclusion: Preoperative preparation of the knee with povidone iodine scrub is a safe method for prevention of infection and can be used instead of the common two-stage method of using povidone iodine scrub and then painting with aqueous povidone iodine since this can decrease the time and cost of surgery.

Abstract
Background and Aim: Conventional post-operative rehabilitation programs focus on quadriceps strengthening and knee range of motion. However, hip muscle weakness is evident in patients with knee osteoarthritis. The present trial study aimed to investigate the effects of adding early hip muscle strengthening exercises to conventional rehabilitation programs on pain, Range of Motion (RoM), Quality of Life (QoL), and physical function in patients with unilateral Total Knee Arthroplasty (TKA).
Methods & Materials: The intervention was initiated from the second day after surgery and continued for 10 sessions, 3 times a week on 24 participants in the control and intervention groups. Both research groups received Transcutaneous Electrical Neural Stimulation (TENS) and Infra-Red (IR), followed by exercises. The control group performed knee extensor and flexor strengthening and RoM exercises. The intervention group conducted hip-strengthening exercises in addition. Outcome measures included pain, knee flexion, and extension RoM, and QoL using the 36-Item Short Form Survey (SF-36), Timed Up and Go (TUG) test, Step Test, Six-Minute Walk Test (6MWT), and Hip and Knee Muscle Strength test.
Ethical Considerations: This research was approved by the Research Ethics Committee of Iran University of Medical Sciences (IR.IUMS.REC.1396.9511340012) and it was registered in the Clinical Trial Registration Center (Code: IRCT 20150314021459N6).
Results: All outcome measures improved in both research groups. The improvement in the scores of pain (P=0.03), knee extension RoM (P=0.007), and TUG test (P=0.033) were significantly higher in the intervention group, compared to the control group. The strength of knee flexors (P=0.023), hip flexors (P=0.040), hip extensors (P=0.028), hip adductors (P=0.040), and hip external rotators (P=0.047) significantly improved higher in the intervention group.
Conclusion: According to the present research results, both treatment approaches were effective on patients with unilateral total knee arthroplasty. Considering the better result of some of the outcome measures in the intervention group, the addition of hip strengthening exercises to knee exercises can be useful.

Abstract
Background and Aim: Patellofemoral Pain Syndrome is one of the most common musculoskeletal problems in the elderly that Can affect their daily activity. This study aims to compare the effectiveness of a period strengthening core stabilization exercise with the Knee strengthening exercises on improving pain in female athletes with Patellofemoral Pain Syndrome.
Methods & Materials: In this study, 20 female athletes with Patellofemoral Pain Syndrome participated. They were accidentally divided into two groups: strengthening core stabilization exercise (10 people( and strengthening knee exercise (10 people). A visual analog scale measured patients’ pain before and after eight weeks of practice interventions. Paired t-test and independent t-test were used at the significant level of (P<0.05) to analyze the results.
Ethical Considerations: This study was approved by the Research Ethics Committee of Bu Ali Sina University Hamedan (Code: IR.BASU.REC.1398.032).
Results: The results showed that the pain level in both groups decreased significantly after strengthening core stabilization exercises (P=0.006) and the Knee strengthening exercises (P=0.000). Although intergroup comparison did not show a significant difference in the results (P̀=0.064), the calculation of the effect showed a more significant effect of strengthening knee exercise [ES=1.8) on the improvement of pain compared to the strengthening core stabilization group (ES=0.7).
Conclusion: The results showed that knee strengthening and core stabilization exercises reduced the pain. But due to the higher effectiveness of knee strengthening exercises in improving pain, it is recommended to use this protocol to reduce the pain of these patients.

Abstract
Introduction: Exercise and physical activity have always been recommended as a core treatment for knee osteoarthritis. However, it is unclear which types of exercises have the most splendid effect on this condition. This study aimed to evaluate the impact of two methods of water exercise (Traband exercise and NASM exercise) on pain and motor function in women with knee osteoarthritis.
Methods: In this semi-experimental study, with a design pre and post-test and a control group, 45 women with knee osteoarthritis with an average age = 56.5 years and a BMI = 29.04 kg/m2 were purposefully selected and divided into three groups (n = 15); Water Exercise with Theraband, Water Exercise with the NASM Approach and Control randomly. An exercise protocol with Theraband and NASM approach (approved by the Medical College of Georgia for patients with knee osteoarthritis) was performed for eight weeks, three sessions per week, and each session lasted about 60 minutes in the water. Visual Analog Scale (VAS) and physical performance tests of the Osteoarthritis Research Society International (OARSI) were used to estimate the study variables. MANCOVA and post hoc Bonferroni tests were conducted to analyze the data at a significant level (P ≤ 0.05).
Results: The results showed that, similarly, in both experimental groups, the amount of pain and the time of tests TUG, 40MW, and SCT decreased significantly (P≥ 0.05). In addition, in both experimental groups, there was a significant increase in the scores of the 30-S-CS and 6MWT tests (P≥ 0.05).
Conclusions: These results showed the beneficial effects of training in water with the traband and training in water with the NASM approach on pain and motor performance indicators. Therefore, the use of these training methods is recommended as a suitable prevention and treatment method for knee osteoarthritis.
