That was indeed good news. My sister in law had her knew replaced earlier this year and hasn't complained any at all... plus my older sister had her second knee done about April... she still uses the cane, but lives alone and seems to be getting along well with them... she did say she can't mow her lawn anymore.... but she is 81 years old.
My wife had her right hip done in 2008, the second hip last year.... she gets around okay, she also has to use a cane, but she's also got other issues with her back that requires that.... she had a septic infection in 2013 that put her in hospital and nursing center for about 5 months and left her with a couple of fused vertebrae that gives her lots of back pain.... she's 76.
