Hi Brickey. I would suggest you get the paperback book Pain Free by Pete Egoscue. You can visit his site at www.egoscue.com and even write them about your problem and ask if their stretches will help, but I'll tell you now, that they will.
I have seen some amazing things happen in situations like yours. Even though it's bone on bone and doctors will tell you there's nothing you can do except replace the knee, this isn't true. I'm enclosing a couple messages I sent to some other people. I have even more remarkable Egoscue stories, but these pertain to your situation. There's a wonderful, cheap paperback book out called Pain Free by Pete Egoscue. I usually find them in the used book stores, too. The 'exercises' are actually nothing more that specific stretches. When a person first starts doing them it can take up to 40 minutes before relief is felt, but if you continue to do these stretches every day, this time should shorten down to about 10 minutes. They should be done first thing in the morning so that the effect lasts all day. Eventually (usually no more than a few weeks) the body will relearn to use the correct muscles and the back problems disappear. The book is listed for various parts of the body, so that a person can start with stretches specific to that area--such as shoulders, back, knees, etc--and once the correct muscles are being used again, then you go on a maintenance program for support of the whole body. You can also go to www.egoscue.com and read about it there. They do have a way where you can take photos of your husband, upload the photos, pay the consultation fee and they will determine exactly which exercises he needs. But I've found that the book pretty much covers all the common problems without having to go through a consultation. AND For your knees--please get the book Pain Free by Pete Egoscue. It's a cheap paperback and has been out a long time, so if you have a used book store in your area you can probably find it there. I've seen some of the most remarkable 'healings' take place due to simply following the stretches in that little book. Egoscue has a web site you can visit www.egoscue.com and you can even write and ask them if they think the stretches will help you. But I know they will. They would prefer you to visit a trained therapist, but unless you live in California where the main clinic is located, it's hard to find a therapist that knows egoscue. But--here's the story of the first time I saw Egoscue stretches in action. I was in a group of people listening to a lecture by Pete Egoscue's right hand man, talking about how the wrong muscles are being used to do the job of holding our bodies together and doing its jobs, because of some trauma, or illness, or just because we stand and walk incorrectly. He looked through the audience and asked if anyone had any pain right then. About 3/4s of the hands shot up. :-) He picked one lady and she stood up and said that she had knee pain in one knee every time she stepped. He asked if she had it now and she said--not unless she walked, and then it was excruciating. She said the doctors already planned to replace the knee. He told her to come up front, then had her put her hands, fingers interlocked, behind her head. He said 'pull your shoulders back' and 'walk around the room'. She did. He went on lecturing, the audience watching him I watched her. You could see her eyes getting bigger and bigger. When she got up front again she stopped. He said "I didn't tell you to stop Keep walking" so she walked around the room a second time. When she got to the front again he said "stop". He asked her if her knee hurt. She had the most surprised look on her face and said NO. He said any pain at all and she said not even once! He said--"you are carrying yourself wrong. You are using the wrong muscles to hold the knee in place. Now, you can't walk around all day with your hands behind your head, but if you do the stretches I'll show you later, you will teach the correct muscles to do their job. You don't need knee surgery You just need to use the right muscles". So--get the book and go right to the knee section. It's set up for each body section that can hurt. Once you are out of pain for 24 hours (doesn't take very long to get like that) then you can start doing full body stretches. The book explains everything. As I' said, I have some incredible stories about how these simple stretches have preformed "miracles". Best thing is to do them first thing in the morning, because then it sets up for all day without pain. When you first start it can take up to 45 minutes to do the stretches (simple things, you just basically lay there mostly, till things relax) but after you get out of pain and get your body working right, it usually only takes about 10 minutes to keep things working right.
