Abstract Background Knee dislocation is a serious injury, representing less than 0.2% of all orthopedic injuries, and 16% to 40% of these patients suffer an associated injury to the common peroneal nerve (CPN). However, it is still unclear which structures are most intently associated with CPN injury. This study attempts to analyze the potential risk factors for CPN injury and provide clues for a comprehensive diagnosis of knee dislocation. Methods We retrospectively reviewed 153 cases of knee dislocation related to lateral and/or posterior ligament injury between 2015 and 2018. All 153 patients were divided into the CPN injury group or the no-CPN injury group. The baseline characteristics included age, gender, cause of injury, posterior cruciate ligament (PCL) disruption, anterior cruciate ligament (ACL) disruption, popliteofibular ligament and/or tendon of popliteus injury, biceps femoris tendon injury and fibular head fracture. We identified potential variables for a multivariable logistic regression model to identify the major risk factors for CPN injury. Results Multivariate regression analysis revealed the biceps femoris tendon injury and fibular head fracture to be predictive of CPN injury in knee dislocation. Gender, age, cause of injury, ligamentous classification, popliteofibular ligament and/or tendon of popliteus injury, PCL disruption or ACL disruption do not predict CPN injury. Conclusions Biceps femoris tendon injury and fibular head fracture are risk factors of CPN injury in knee dislocation. A better understanding of the risk factors for CPN injury allows surgeons to achieve more accurate diagnoses.

Biceps Femoris Tendon

Chronic menstrual dysfunction and low female sex hormones adversely affect muscular performance in women but studies in college athletes are scarce. A cohort of 18 Japanese, female college athletes at the University of Tsukuba, Japan, were recruited and studied over 3 weeks under 2 conditions. One group had normal menstrual cycling (CYC, 9 athletes) while the other had irregular cycles (DYS, 9 athletes). Hormones and creatine kinase (CK) were measured from blood under both rest (RE) and exercise (EX) conditions. Biceps femoris tendon stiffness was measured by myometry. No differences in age, height, weight, menarche age, or one-repetition maximum weight existed between the groups. The DYS group had persistently low levels of estrogen and progesterone. In the CYC group, the CK level significantly increased at each point immediately post-exercise and 24 h post-exercise compared to pre-exercise in Weeks 1 and 2, and significantly increased at 24 h post-exercise compared to pre-exercise status in Week 3. The DYS group was significantly different only between pre-exercise and 24 h post-exercise over all 3 weeks. The DYS group also suffered from higher biceps femoris tendon stiffness at 24 h post-exercise. Chronic menstrual irregularities in Japanese college athletes increase muscle damage markers in the bloodstream and muscle stiffness after acute strength training.

Context:Proprioceptive neuromuscular facilitation (PNF) is commonly used before competition to increase range of motion. It is not known how it changes muscle response to rapid length changes.Objective:To determine whether PNF alters hamstring muscle activity during response to rapid elongation.Design:2 X 2 factorial.Setting:Laboratory.Participants:Twenty-four women; means: 167.27 cm, 58.92 kg, 21.42 y, 18.41% body fat, 21.06 kg/m2BMI.intervention:Measurements before and after either rest or PNF were compared.Main Outcome Measures:Average muscle activity immediately after a rapid and unexpected stretch, 3 times pretreatment and posttreatment, averaged into 2 pre-and post- measures.Results:PNF caused decreased activity in the biceps femoris during response to a sudden stretch (P= .04). No differences were found in semitendinosus activity (P= .35).Conclusions:Decreased muscle activity likely results from acute desensitization of the muscle spindle, which might increase risk of muscle and tendon injury.
