All the guys with knee replacements I've talked to, say their doctors advise against running and singles tennis.
Correct, play on clay or grass and life expectancy of knee replacement will be much better, hard courts tale a toll. 6 months however is ridiclous and an anomaly. I'd say 5-10 years is a likely life expectancy for someone who plays frequently - there are a ton of variables however.
