I had Knee trouble following a knee cap fracture as a teen. It was on going for about 30 years. The other knee started to give trouble, probably because of the extra load put on it. Since about 1995 I have taken glucosamine & have not had any knee problems. Prior, I used to have at least 1 dislocation each year.
It has worked for me!!
This week, I have been in hospital having a shoulder operation; rotator cuff repair and other work following an injury about 18 months ago. The surgeon had me stop taking it 3 months ago in prep for the shoulder work. My knees have been some what 'wonky' during this time. I am due back on the glucosamine in a couple of months.
If its only a placebo, its a good one !!
