Should the semimembranosus become attached to the pes via cross

attachment to the semitendinosus tendon, then the huge semimembranosus becomes a ‘high speed’ muscle whode spindles become ‘screamers’. When open lengthening surgery uses a common incision toboth tendons, and thus removes the fat barrier between them then this possibility becomes very real. We would EXPECT, given a huge conversion to high speed spindles from the slower ones, that spasticity would become worse. It does. The sartorious path is different in that flexion makes it looser. Interestingly, sports surgeons have noticed seemingly less control at high speed in athletes who have

had the semitendinosus harvested to rebuild their knee ligaments. This is a musing not proven but it does [now] make sense. So is the ST muscle an evolutionary muscle we don’t need. Maybe. But it may have found another employment after time as a super speed component of the spindle control system.
