Knee Injury at Work in Pennsylvania: Meniscus, ACL and Kneeling Trades

The two patterns

Acute. A twist on a ladder, a fall from a step, a knee taking the weight during an awkward lift. These produce meniscus tears, ligament injuries and sometimes fractures, and they have a date and often a witness.

Cumulative. Flooring, plumbing, roofing, warehouse work on concrete, anything involving years of kneeling, squatting and stair climbing. These build up, and because there is no incident the notice question becomes the battleground.

Meniscus tears and the degeneration argument

Meniscal tears appear on imaging in people with no symptoms, and insurers use that the same way they use degenerative disc findings. The answer is the same: Pennsylvania compensates aggravation, and the question is when the knee stopped working rather than when the tissue first changed.

Knee replacement

Where a work injury accelerates arthritis to the point of replacement, the claim can include it, and it materially changes valuation. A replacement carries permanent restrictions, a finite prosthesis lifespan and the realistic prospect of revision surgery later in life.

Settling a knee claim before understanding whether a replacement is coming is one of the more expensive mistakes available.

Specific loss

Permanent loss of use of a leg carries a specific loss award separate from wage loss and payable whether or not you returned to work. Worth asking about explicitly in any knee case with lasting limitation.
