I slipped mopping the floor and my left leg got strained.  I didnt fall or break anything.  I might have heard a pop at the top of the leg.  The back of my L leg from top to knee hurts.  Hard to bend, hard to go up stairs, and really difficult getting up from sitting.  Most comfortable to walk without putting left leg toward the lead; have to catch it up with the right leg. Muscle strain? How to treat?
Hello, I have studied your case. As per your history there is possibility of soft tissue injury in knee. Most commonly meniscus injury occurs may be associated collateral ligament injury. You may need to do MRI knee to see for any functional defect. As per your symptoms you need to do physiotherapy and knee exercises to improve range of motion. Rest and ice fomentation along with supportive brace will help to reduce locking episode and pain. Small meniscus tear can be managed conservatively with physiotherapy with USG and TENS. Large meniscus injury can be managed by arthroscopic repair. Another possibility of patellar ligament tightness which can be evaluated clinically. Hope this answers your query.
