The incidence of meniscal tear associated with ACL injury is higher in chronic cases; the number of medial meniscal tears is particularly high, many of which require meniscectomy. Early ACL reconstruction is recommended also for the prevention of secondary meniscal tear.

BackgroundLittle is known about risk factors that may prevent hip fracture patients from being discharged to home. The present study was developed to investigate possible prognostic factors.Materials and methodsWe studied 345 patients with hip fracture treated at our hospital since 1997, who were living at home before the injury. There were 84 males and 261 females. Mean age at injury was 81.6 years. Fracture type was femoral neck fracture in 152 patients and trochanteric fracture in 193. Patients were divided into those who were discharged to home (home discharge group) and those who were discharged to rehabilitation facilities or died in hospital (non-home discharge group). Gender, age at admission, fracture type, and other factors were investigated. Multivariate analysis was conducted on these variables for the home discharge and non-home discharge groups.ResultsThere were 202 patients (58.6%) in the home discharge group and 143 patients (41.4%) in the non-home discharge group. The factors significantly associated with not achieving the goal of discharge to home were age 85 years or above [odds ratio (OR) = 1.79, P = 0.0204], chronic systemic diseases (OR = 1.77, p = 0.0225), dementia (OR = 3.17, P < 0.0001), and walking disability before injury (OR = 5.70, P = 0.0328).ConclusionsIn elderly patients with hip fracture, the risk factors that predict difficulties with discharge to home include age at admission, concomitant chronic systemic diseases and dementia, and walking disability before injury.

Background We have reported that the functional outcome in elderly with hip fracture is related to age at admission, dementia, and anemia. In this study, we examined the relationship between hemoglobin level at admission and walking ability, as well as survival outcome at discharge. Materials and methods We studied 394 patients aged 60 years or older treated at our hospital for hip fracture since 1997. Anemia was defined as an admission hemoglobin level\13.0 g/dl for men and\12.0 g/dl for women. The relationships between anemia status with age at admission, gender, fracture type, residence before injury, walking ability at discharge, length of hospital stay, and survival outcome were analyzed. Results Anemia was observed in 266 of 394 patients. Univariate analysis identified no relationship between the status of anemia and age, gender, walking ability before injury, treatment modality, or length of hospital stay. On the other hand, 106 of 266 patients in the anemic group were residing in institutions, and as many as 72.9% of patients in the anemic group had trochanteric fracture. For walking ability at discharge, 92 of 128 patients without anemia were ambulatory compared with only 130 of 266 patients with anemia, with a significant difference between the two groups. Furthermore, there were 15 in-hospital deaths in the anemic group compared with one death in the nonanemic group. Multivariate analysis identified three independent items: age, fracture type, and walking ability at discharge, as related to the status of anemia. Conclusions Hemoglobin level at admission is related to outcome in patients with hip fracture.

Arthroscopic knee surgeries are considered to be minimally invasive, and are conducted relatively safe with low complication rates. In this series, however, seven cases of complications occurred, including two cases (0.08 %) of septic arthritis. Furthermore, symptomatic thromboembolism has been reported to occur also in arthroscopic surgery. The risk of severe complications has to be acknowledged.
