These account for 1-3 percent of all osteogenic sarcoma. A thirteen-year-old female presented with pain and swelling over her right thigh for a duration of three months with no history of trauma. The diagnosis of osteosarcoma was suspected through radiology which incidentally also showed the other femur to have involvement while getting the MRI scan. A suspicion of either metastatic osteogenic sarcoma or multifocal osteosarcoma was made and CT of the chest was done to look for pulmonary metastasis. The diagnosis was confirmed by biopsy from the right thigh. The diagnosis was confirmed as metastatic osteogenic sarcoma. There is always suspicion whether these tumors represent osseous metastasis or are of multicentric origin. This case is of interest because there was high suspicion that it could be multifocal osteosarcoma which would have been a very rare case.

Laxity can be tested by clinical and arthrometer preoperatively as well as postoperatively. The purpose of this study is to evaluate postoperative laxity in Nepalese population. Materials & methods This retrospective study was carried out in Grande International Hospital, Kathmandu. All cases which had completed six-months follow up and presented in outpatient department were included in the study. Laxity was tested by Karl Storz Arthrometer using anterior force in 20 degrees of knee flexion with maximum manual force by the same doctor. The statistical significance level was set at p=0.05. Statistical analysis was done using SPSS 16. Results 21 cases operated via arthroscopic method were eligible for the study. Mean age was 28.3±10.44. There were 14 (66.7%) male 7 (33.3%) female. A total of eight cases of laxity (36.36%) were identified-six males (75%) and two females (25%). Hamstring grafts accounted for three cases of laxity (37.5%) while Bone Patellar Tendon Bone Graft (BPTB) accounted for five cases (62.5%). The mean follow-up was one and half years. Hamstring and bone patellar tendon bone graft were used in 6 (28.6%) and 15 (71.4%) cases respectively. Conclusion Previous studies have concluded that >3mm of laxity difference is associated with difficulties in vigorous activities. However, our patients were comfortable in their daily activities without significant clinical outcome.
