Fifteen cases with ruptures of musculotendinous juncture of the medial head of the gastrocnemius muscle which occurred during sports activities were studied. Of these cases, 7 were males and 8 were females. The mean age was 36 years and 6 months with ages ranging from 15 to 56.Six of these cases were involved in track-and-field events, three in volleyball, two in softball, two in badminton, one in judo and one in recreational game. Prodromic symptoms such as dull aching of the affected leg were seen in 8 cases. All cases were injured in a position of the ankle joint in dorsiflexion with the knee joint in extension.Conservative treatments resulted in a satisfactory recovery of their activities of daily living in all cases.The results indicated that prophylactic stretching is of value for preventing this injury, especially in middle-aged players.
