The 'half knee' op is as successful as the total replacement. What you have to consider though is that if you continue to have arthritic changes on the remaining joint surfaces you will require a revision to a total replacement in the future.

Make sure the chest strap is adjusted to take the weight off your shoulders. You can get some good padding products 'off the shelf' that might be worth using until the bruising has resolved. Look for thick padding squares that are typically sold to protect sore heels and bony prominences.
Just a sort of side-thought... if one shoulder is worse than the other, is your gait in general asymmetrical? Might be worth working on.
