Background: Knee osteoarthritis is a common etiology of disability in older age group. There are evidences suggesting that varus or valgus deformity can be from distal of femur, proximal of tibia or because of ligamentous laxity. Osteotomy in incorrect location may create zigzag deformity and may contribute to increase risk of osteoarthritis. The objective of this study was to find the correct location of deformity in genuevarum or genuevalgum.Methods: We studied 40 patients with knee deformity at a mean age of 27.4 years (19-38), prospectively. Standing 3-point view radiographs were obtained on each patient, and the limb axis was determined. The data on limb malalignment was analyzed statistically.Results: In 94.5% of cases the location of varus deformity was proximal of tibia and in 5.5% in distal of femur, the best location of osteotomy. Our study also revealed multiple factors contributing to varus deformity, i.e. distal femur in 67.5%of cases, proximal tibia deformity in 92.5% of cases and ligamentous laxity in 77.5%.Conclusions: Varus knee deformity can be from proximal tibia, distal femur or knee laxity. Before any corrective surgery one must clarify location of deformity

Background: Rotator cuff tear is one of the major causes of shoulder pain and disability especially in over 60 year old age people. The problems with arthroscopic repair and also failure to repair with strong and valuable sutures in massive tears have increased the trend towards open surgery. This study was done to assess repair of rotator cuff tear by open surgery.Methods: In this cross-sectional study, 14 candidates (8 female, 6 male) for rotator cuff surgery, were assessed for shoulder function by the use of ASES and SST scoring systems, before and after surgery, by the same observing orthopaedic surgeon.Results: Mean age of patients was 57.94±14.04 years old. The mean SST score before surgery and 6 and 9 months after surgery were 10.17, 10.67 and 10.81, respetively with a significant post-operative improvement (p < /em>=.026). The mean ASES score before surgery, 6 and 9 months post surgery were 42.82, 47.95 and 57.43, respectively showing significant improvement after surgery (p < /em>=.025).Conclusions: The open surgical repair of rotator cuff tear is effective and shoulder function improves and pain decreases significantly. This is with the technique of constructing a surface, rather than making a trough, and also using of interoseous suture rather than anchor suture.
