Coach Steve Hansen has gone out on a limb to be fully fit for Wales' World Cup campaign next month.
The New Zealander went under the knife on Monday as an old rugby injury flared up during the team's pre-Cup warmup in Lanzarote.
"It's an old knee injury which has been playing up for about six months," team manager Alan Phillips said. "It's a cartilage thing - they just went in there and cleaned it up. He was in and out on the same day."
Phillips said there were no serious injuries among the 30-man squad, although there was "plenty of fatigue and the odd ankle strain".
"They really put the work in over there, fair play to them," the former Wales hooker said.
"There are a lot of tired bodies in the team."
Phillips said it was too early to say if all 30 players would take part in a training match at the Millennium Stadium on Wednesday.
The annual Women's club launch was held at the Wales Centre of Excellence where National Women's Head Coach and Programme Lead Rhys Edwards, Competition Secretary Adrian Howell and Cardiff Met player Ffion Jones express eagerness for the new campaign to get under way.
