Range of motion should be assessed by extending and flexing the knee as far as possible (normal range of motion: extension, zero degrees; flexion, 135 degrees).oving the patient's knee through a short arc of motion helps identify the joint lines.

Introduction. An interest rate swap is a contractual agreement between two counterparties to exchange cash flows on particular dates in the future. There are two types of legs (or series of cash flows). A fixed rate payer makes a series of fixed payments and at the outset of the swap, these cash flows are known.o value a swap, the present value of cash flows of each leg of the transaction must be determined. In an interest rate swap, the fixed leg is fairly straightforward since the cash flows are specified by the coupon rate set at the time of the agreement.
The exchange of interest rates for the mutual benefit of the exchangers. The exchangers take advantage of interest rates that are only available, for whatever reason, to the other exchanger by swapping them. The two legs of the swap are a fixed interest rate, say 3.5%, and a floating interest rate, say LIBOR + 0.5%. In such a swap, the only things traded are the two interest rates, which are calculated over a notional value. Each party pays the other at set intervals over the life of the swap. For example, one party may agree to pay the other a 3.5% interest rate calculated over a notional value of $1 million, while the second party may agree to pay LIBOR + 0.5% over the same notional value.
