The crutches and the boot make the recovery easier because it relieves the weight and pressure from the injured body part. I'm not sure what it means for TP to have 1 ligament. It almost makes it sound like he's a bit like DeJuan, who has no ACL's but the way that I interpret that is that TP injured the #1 most common ligament for ankles. The ATFL or anterior talofibular ligament.
I don't think TP only has 1 of 7 ligaments for his Ankle:
Primary ligaments of ankle include (see below for details)
Deltoid ligament
Calcaneonavicular ligament (Spring Ligament)
Syndesmosis (includes AITFL, PITFL, TTFL, IOL, ITL)
Anterior talofibular ligament (ATFL)-This is the one that is most commonly sprained.
Posterior talofibular ligament (PTFL)
Calcaneal fibular ligament (CFL)
Lateral talocalcaneal ligament (LTCL)
But hey...Like I say, I expect Parker to play against the Clippers and the Heat at the end of March.
