But his joy was short-lived and he admits he has had a tough time on the sidelines, missing Wales' summer tour to South Africa and the recent autumn series.
"One week I was beating France and winning the Grand Slam and the following week was the injury," said Phillips, who has won 33 caps.
"Going from such a high to a low was very hard to take on board and it's been a very slow process.
"It's been a tough road but I'm at the end now and I'm really looking forward to being back playing."
Phillips came through his run-out against the Dragons largely unscathed, despite taking a minor knock.
"Personally for me, I'm delighted to be back on the field," he told BBC Sport Wales.
"It's all about having time on the field and it's going to be a bit of a process and I'm not putting too much pressure on myself.
"I took a bit of contact [on Friday], but the knee felt fine afterwards and I was initially pleased to come through it."
