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.

Background: Shoulder arthroplasty improves shoulder Range of motion (ROM), strength and function in patients with advanced shoulder disease. However, clinical outcomes vary and are not always predictable among patients. Pre-operative factors and patients’ characteristics may influence improvement after surgery. This study examined the impact of the pre-operative objective measures Range of motion (ROM) and strength, age, sex, and comorbidities on shoulder ROM, strength status and the amount of improvement one year following shoulder arthroplasty. Methods: 140 patients were assessed pre-operatively and one year after shoulder arthroplasty in this prospective cohort study. Pearson’ s correlations and multiple regression analyses were performed to test the impact of potential predictors on abduction, flexion, internal rotation and external rotation ROM as well as on shoulder abductors, flexors, internal rotators and external rotators strength at one year. Results: Pre-operative ROM significantly predicted 10%-37% of the improvement in ROM after surgery. Less preoperative ROM was associated with a greater improvement in ROM. Less pre-operative muscle strength was associated with a greater improvement in strength after surgery. Pre-operative shoulder muscles predicted 28%-38% of the strength status at one year, and 24%-43% of the improvement in strength postoperatively. Older age was associated with less improvement in ROM and strength at one year. With other predictors, age explained 37% of the change in ROM and 36% of the change in strength. Male sex was associated with greater improvement in muscle strength. Sex significantly predicted 24%-36% of the change in strength. Conclusion: Pre-operative ROM and strength, age, and sex are significant predictors of the improvement in the shoulder ROM and strength one year after shoulder arthroplasty. The improvement in these measures is expected to decline with age and men are expected to gain more strength than women following this surgical intervention.

Background: Range of motion after total knee arthroplasty is an important factor measuring of the outcome and is crucial factor all of rating knee system. Our study was down to identify the most important factors that related with postoperative Range of motion. Materials and Methods: We studied prospectively patients (68 knees) who had a primary total knee arthroplasty at the same center between 2000-2002. Ten preoperative factors (age, sex, extension lag, flexion contracture, flexion arc, tibiofemoral angle, body mass index, cause of joint destruction, prosthesis type about PCL retention or substitution, history of high tibial osteotony) were used to predict postoperative Range of motion. Results & Conclusion: We used correlation analysis tree to identify the preoperative factors predicting the postoperative Range of motion. The significant factors were preoperative Range of motion, preoperative tlexion contracture and body mass index.

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.
