if there is still some swelling around the joint, it can give the sensation of it feeling stiff when you move it.as with any joint, there are a lot of structures with not a lot of free space, so when there is swelling taking up space where there isnt any, it can feel stiff. im a firm believer of the benefits of ice, even this far down the line you may still have some intrarticular inflammation or swelling so keep icing it.


you may have some muscle tension/stiffness too, so make sure you complete hamstring stretches, static and dynamic as part of your routine, the stretches are just as important as strengthening ex's.

this far post surgery, id recommend doing single leg work, so like your doing single leg squats, single leg balance on/off wobble cushion,quad extensions (double leg),
, single leg dips on affected leg and reaching forward back side to side with the unaffected leg (clockwise circle), if you can do impact, then single leg hops forward/back/side to side, lunges with and without resistance.
if you are running with no adverse affect start doing agility drills such as light jogging forward,backwards,sideways, high knee jumps into a light jog. things like that.


dont forget to strengthen your hip too, so some gluteal strengthening and condition, hip abduction, walking sidewyas with theraband, clam exercises, bridging.
