Predators goaltender Pekka Rinne recently underwent arthroscopic surgery on his left hip, general manager David Poile said Thursday.

The recovery time is four months, Poile said.

The star netminder saw his numbers drop this season after consecutive years of being named a finalist for the Vezina Trophy, given annually to the NHL’s top goaltender.

Rinne had a 2.43 goals against average and .910 save percentage, his lowest numbers since the 2009-10 season.

He also played 22 games in the Kontinental Hockey League with Dinamo Minsk during the NHL lockout.

Other notable NHL goaltenders have undergone hip surgery and recovered with strong seasons.

Former Bruins netminder Tim Thomas, who underwent surgery for a torn labrum in his left hip in the summer of 2010, won the Vezina for the 2010-11 season with a 2.00 goals against average and .938 save percentage. According to a Boston Globe story, Thomas’ recovery was 3-4 months.

He was also awarded the Conn Smythe Trophy as the NHL’s playoff MVP in the Bruins’ run to the 2011 Stanley Cup.
