Background: The objective of this study was the evaluation of genovarum adjustment and the effect of distal part of osteotomy displacement and comparing it with other methods and determination of its complications.Material and method: A total of 25 knees from 22 patients in 1381-1383 in Baghiatallah Hospital were undergone proximal tibia osteotomy by lateral closing wedge (Coventry) method with rigid fixation by T-plate and rapid range of motion (ROM). In all patients the distal of osteotomy part was displaced about 1 cm to proximal and was fixed rigidly with a T-plate. ROM and 50% weight bearing with 2 crutches were begun at second day after surgery. After 6 weeks both crutches were put away. Patients were visited again at the end of weeks 4, 6, 8, and 16 and tibio-femoral angle and ROM were measured and registered. Every probable complication and union at any time and patient’s satisfaction and the time of getting back to work were registered at the fourth month.Results: The mean of genovarum was 12 degrees varus before surgery which was adjusted to 6.1 degrees valgus after surgery. The majority of patients were able to walk without crutches at the end of the second month. There was union in all patients at the end of the third month. At the end of the fourth month all patients got back to previous activities. There was pain in only one patient (2 knees), but it was milder than before and the patient was satisfied.Conclusion: It seems this kind of operation is more advantages than other methods especially non-rigid fixation and casting in patients older than 40 with osteoarthritis and no tolerance to being immobilized in cast and also with high complication risks such as vascular thrombosis.

The purpose of this study was to compare trunk core stability and flexibility between bodybuilders and non-athletes. 60 subjects participated in this study (30 bodybuilders and 30non-athletes). The subjects were selected between healthy elite bodybuilders and healthy non-athletes. For core stability measuring (flexion, extension and lateral bridge) Mc Gill tests was used. Trunk flexibility in flexion, extension, right and left lateral flexion and right and left rotation was measured by meters. the results showed that the time of flexion stability in bodybuilders were significantly lower than non-athletes (p=0.001) and also flexibility of flexion (p=0.03) and extension (p=0.02) in bodybuilders group was significantly lower than non-athletes, but the range of motion ratio in different direction (Flexion to extension, right and left lateral flexion and right and left rotation) were not significant between two groups (p<0.05). The findings of this study showed that bodybuilders have lower core stability in flexion direction than non-athletes, and lower flexibility in flexion and extension direction than non-athletes, this point.

Purpose: To compare the range of motion of hydroxyapatite (HA)and porous polyethylene (Medpor) ocular implants in enucleated eyes.Methods: This comparative study was performed on records of 34 patients who underwent Unilateral nucleation and implantation of hydroxyapatite (13 cases) or Medpor (21 cases). The two groups were compared regarding age, gender, cause of enucleation, laterality, and movement.Results: Patients were male in 55.9%. Mean age of patients was 29.7 year (1-61 years). The most common cause of enucleation was trauma (55.9%) and the most common complication was mucopurulent discharge (14.7%).There was no case of extrusion, migration or exposure. Moderate to good motility was achieved in 89.3% of patients in the Medpor group and 86.6% in the HA group. There was no statistically difference between the two group regarding upward movement (P=0.68), downward movement (P=0.62), adduction (P=0.17) and abduction (P=0.65).Conclusion: Medpor and hydroxyapatite ocular implants are comparable regarding range of motion.

This report describes a rare intra-articular benign tumor, lipoma arborescens, of the knee joint in a 21 year-old female. The patient suffered from left knee joint swelling for five years with occasional pain. Swelling was soft and boggy in the suprapatellar area. Motion of joint was complete. No abnormality was detected in any laboratory tests. MRI showed a large soft tissue density in the suprapatellar area with high signal intensity on T1 and T2 weighted images. Operative arthroscopy revealed a creamy brown hypertrophied synovium with diffuse papillary processes characterized by villous proliferation of the synovium infiltrated by mature fat tissue, chronic inflammatory cells and vessels as seen in the pathologic slides. Lipoma arborescens or villous lipomatous proliferation of the synovial membrane should be distinguished from other similar lipomatoid conditions such as synovial lipoma and Hoffa disease. Lipoma arborescens should be considered in patients with painless, slowly progressive swelling of a joint, especially the knee.

Introduction: This study aimed to compare the improvement of the activity content and pain reduction in patients with patella displacement after total knee arthroplasty surgery with and without correction. Methods: This study was conducted on all patients over 18 years of age refer to Baqiyatallah Hospital suffering from patella displacement, on patellar view radiography, were candidates for knee joint replacement, and underwent joint replacement. Thirty-five patients with deviation and required removal of the patella bone, whose problem was corrected after total knee joint replacement, with 35 patients whose deviation and displacement of the patellar bone was not restored after total knee joint replacement. Reducing the VAS and improve the range of motion (ROM) was assessed in the follow-up periods of 1, 2, and 4 months postoperative. Evaluation of the presence of deviation and displacement of the patella and its correction was done based on the radiograph of the patella view at an angle of 90 degrees. Results: In examining the range of motion, the results showed that the patients in the cases and control before surgery had no significant difference in the range of motion (P=0. 001). This is while a statistically significant difference was reported in the patient's range of motion between the two groups at one month, two months, and four months after surgery (P=0. 001). The average pain before surgery was similar in the two groups (P=0. 953). The average pain in one, two, and four months after surgery in the modified group was lower than in the non-modified group (P=0. 001). Conclusion: This study showed that the range of motion in the modified group was higher one month, two months, and four months after surgery. Also, the average pain one, two, and four months after surgery in the modified group was lower than in the unmodified group.
