I am 22 years old. I had a very athletic lifestyle. Four months ago, I went down a steep hill on a skateboard at around 15+ MPH. I lost my balance and landed hard on left knee. I went to a health clinic right away and took an x ray as well. The doctor and nurse told me that there was no meniscus damage nor any bone fractures. I went home and was bed ridden for the next few days. I took the next 2 weeks off from work and dedicated my time to RICE. After those two weeks, I was able to walk again, only with my left leg fully erect. As the weeks went by, my knee started to gain strength and flexibility. However, I was no where near being able to compete in sports like I once was. I decided to get an MRI and the orthopedic specialist told me that I had a partially torn PCL / Grade I PCL "Strain". Yes, strain. Not sprain. That made me really suspicious because strains aren't usaully referred to ligament damages, right? Anyways, he recommended physical therapy and non surgical methods. Ever since then, I have been running and doing physical therapy exercises regularly. However, it has been four months and the idea of running sprints and making sharp cuts and turns still remain very unlikely. When ever I attempt to do so, a shock of pain radiates from the back of my knee and lingers around my upper calf/lower hamstrings. Plus, there is some knee laxity. Is it normal for a Grade I PCL sprain to last this long? How long is too long? Is there a possiblity that knee laxity could be tightened? The idea of giving up sports at 22 years of age is very hard to accept. Should I opt for surgery if this lasts any longer despite what the doctor said?
