Abstract
Background: In this study we evaluated the treatment of giant cell tumor (GCT) of long bones using cryosurgery combined with curettage and polymethylmetacrylate (PMMA) cementing.
Material and methods: From January 1999 to December 2004, twenty patients (mean age at the time of surgery 29.2 years) 13 females and 7 males were included in the study. Cortical disruption were presented in 7 patients 4 with soft tissue extension, but none of them had intra-articular extension of tumor, 3 patients presented with pathologic fracture of distal femoral lesions. These tumors were located in distal femur in 6 patients, proximal tibia in 7, distal radius in 3, proximal femur in 2, and each of proximal humerus and distal ulna in one patient. In each case diagnostic biopsy was done and surgical procedure performed including curettage, power burr of the wall, cryosurgery with liquid nitrogen and finally filling the space with PMMA cementing. The mean follow-up was 34 months (7 to 61 ).
Results: During follow-up, we observed one recurrence of GCT of proximal tibia. Secondary Aneurysmal bone cyst was reported at the site of one primary distal femoral lesion, without any finding in favor of a recurrence. Neurapraxia of the proneal nerve was occurred in one patient with proximal tibia tumor improved after 8 months.
Conclusion: Cryosurgery combined with power burr and PMMA cementing in the treatment of GCT could be an effective approach in tumor eradication. This method obviates the need for extensive resections and reconstructive procedure.

Abstract
Background: Pin loosening and infection in skeletal traction are important problems in orthopedic surgery and methods which are usually used to manage these problems, are costly and sometimes complicated. In this study, the efficacy of using cast support in infection and loosening of proximal tibial pin was investigated.
Methods: In a randomized clinical trial, 60 patients referring to Rasul-e- Akram hospital from 1383 to 1384, who needed to have proximal tibial pin for at least one month, were studied. All patients were treated with oral antibiotic until 24 hours after pin insertion. Depending on using cast support or not, they were randomly categorized into two groups (30, 30). The rate of pin loosening and infection between these two groups were compared.
Results: In the group without cast support infection rate was about %26.7 while this rate was %13.3 in the group with cast support, which means no significant difference (.33). In addition, although the rate of loosening in the group without cast support was more than the other group, it had no statistical meaning. (%20 compared with %10, p= 0.47)
Conclusions: Cast support doesn't affect the rate of pin loosening and pin site infection. However, considering correct technique for pin insertion including prevention of thermal injury and local hematoma is very important. Therefore, the use of cast support is an optional choice up to surgeons' preference.

Abstract
Background: Pain is one of the greatest concerns of patients undergoing total knee arthroplasty (TKA) which is severe and intolerable within 72 hours post-surgery. Appropriate pain management is a key factor in patient's early mobilization, launching physiotherapy, less hospital length of stay and more importantly, patient's satisfaction. New studies with the infiltration of combined analgesic agents peri and intra-articularly has shown encouraging results in pain reduction, good clinical outcome and patient's satisfaction. The purpose of this study was to compare the analgesic effect of locally infiltrated analgesia (I) compared with single injection femoral nerve block (F) and its impact on pain relief, patient's satisfaction, morphine consumption and clinical outcome.
Methods: This research was a double-blind randomized clinical trial on 36 consecutive patients undergone TKA divided into group (F) in which the ipsilateral femoral nerve in the inguinal area was blocked by a single injection of 20 ml ropivacaine (10 mg/ml) and group (I) which a combination of ketorolac, ropivacaine and epinephrine was injected peri and intra-articularly on the knee during TKA. Pain intensity measured by visual analog scale (VAS), clinical outcome (based on range of motion), morphine consumption and patient's satisfaction of pain management after TKA were compared between the two groups.
Results: Pain intensity score (VAS) and Morphine consumption were statistically less in group I than group F during the first 6 hours and 24 hours post surgery respectively (P< 0.05) however, group F had 12-hour VAS score of 5 which was less than group (I) by 1 grade in pain scale (VAS) (P< 0.05). Other parameters were not statistically different in the two groups and patients' response to our pain management protocols proved to be satisfactory in both groups.
Conclusion: Lower level of pain and morphine consumption in group (I) during the first 24 hours post-surgery in contrast to group (F) and its ease of use by a surgeon intra-operatively, introduce local infiltration analgesia as an effective method to decrease the patient's pain and improve patient's satisfaction in early post-surgery period after total knee arthroplasty.

Abstract
Background: The goal of this study was to evaluate, functional capacity of the knee in flexion and internal rotation after hamstring ligament harvest for Anterior Cruciate Ligament (ACL) reconstruction.
Methods: Fifty patients (male and 18-45 years old) with isolated ACL injury, randomly allocated in two equal groups (in one group, ACL reconstruction was performed with Tibialis Posterior allograft and in another group with quadruple hamstring ligament auto graft) and before and 6 months after surgery in both groups isokinetic flexion strength and isometric internal rotation strength of knee evaluated with Biodex System 4 dynamometer and rotational torque recorder, in order. Isokinetic flexion strength evaluated in sitting and prone position the later position was performed for deep flexion strength evaluation. Also subjective and objective assessment of all patients pre operatively and 6 months post operatively was documented with International Knee Documentation Committee (IKDC) questionnaire. In this study for first time, rotational torque strength of knee was recorded with new design measure, from isometric aspect and not isokinetic.
Results: Although significant improvements in IKDC scores, flexion and internal rotation capacity of the knee were observed in both groups, post operatively in respect to pre operatively there was no significant difference between 2 groups. (P<0.05 or more than 95% confidence Interval of the difference)
Conclusion: This study demonstrates that ACL reconstruction surgery, improves knee performance in flexion and internal rotation, regardless of hamstring tendon harvesting. Considering potential complications of allograft (for example: transfer of harmful diseases from donor to recipient), it is logical to use hamstring auto graft ligament for ACL reconstruction surgery. Because result of this study is not longstanding follow up and limited to male sex, for more worthfull conclusion, we suggest future study in both sex and with long duration of follow up.
