Woods added: “My season had ended a little bit earlier than I had expected. I had the procedure a little bit early and got ahead of it.”
Prior to the ZOZO Championship, which begins on Thursday, Woods competed alongside Rory McIlroy, Jason Day and Hideki Matsuyama at The Challenge: Japan Skins.
The exhibition match – where players compete for holes for between $10,000-$100,000 (£7,700-£77,000) – was staged at the Accordia Golf Narashino Country Club in Chiba, which is the same venue as the ZOZO Championship later in the week.
Woods intends to round off his year by playing in the Hero World Challenge from 4-7 December before being USA captain at the Presidents Cup.
He may use one of his four captains picks for the match against Ernie Els’ international team at Royal Melbourne from 13 December.
“I thought that I had enough time to rehab it correctly and be ready for this event, be ready for Hero, and I’m going to Australia either way, whether I’m playing or not,” said Woods.
“It [his recovery] made me more hopeful that I could play this week, play Hero and play Australia. The way I was feeling towards the middle part of the year, it was going to be a tall order to be able to do it all.”
Former Ryder Cup player Nicolas Colsaerts has won his first title since 2012 at the Open de France.
Despite carding a one-over-par 72 in the final round at Le Golf National, the Belgian finished one shot ahead of Denmark’s Joachim B. Hansen.
Colsaerts began the week 114th on the European Tour’s Race to Dubai and in danger of losing his card.
“I’ve been coming here for I don’t know how many years, it’s been a long road, ” he told Sky Sports.
“So many people have supported me over the years, that’s why I get so emotional. I went through ups and downs for so many years now.”
Recent years for Colsaerts had been a far cry from 2012 when he was selected as a wildcard by captain Jose Maria Olazabal to be part of the European team that pulled off the ‘Miracle of Medinah’ when they came from 10-4 down to defeat the USA 14.5-13.5.
Now ranked 424th in the world, rounds of 67, 66, and 67 had given him a three-stroke lead heading into the final round, but there was plenty of drama ahead.
His advantage had gone before he chipped in for an eagle three at the 14th to go back in front of Hansen.
But he shot into the water at the 15th to run up a double-bogey six as the Dane was handed the lead.
Yet Hansen faltered with a double bogey of his own at the 17th, allowing Colsaerts to hang on for his third European Tour title and first since May 2012.
In terms of majors, Woods is the second most successful male golfer of all time with only Jack Nicklaus having won more with 18.
The top 15 players in the world rankings qualify for the Olympics, with a limit of four players from each country.
Beyond the top 15, the 60-strong field will be filled by a maximum of two players from each country who do not already have two or more players in the top 15.
Woods is currently ninth in the world but is the sixth highest-ranked American.
“I went to my first Olympic Games when it was in Los Angeles (in 1984) so now to have the opportunity to be a part of the Olympics, because golf in my lifetime wasn’t a part of the Olympics, is an important aspect for us and the growth of the game,” Woods told Reuters.
“The game has become so global, and so reaching, that I think the Olympic Games is a great extension of that and I’d like to be a part of it.”
Justin Rose won men’s gold for Great Britain in Rio when golf appeared at a Games for just the third time and first since 1904.
McIlroy’s last major triumph came at the same venue in 2014 although he did win the PGA Tour’s Fedex Cup title this year and was also named player of the year by his fellow PGA Tour professionals.
“Look I love Rory he’s a great player and he’s fun to watch, but it’s just hard to believe there’s a rivalry in golf. I just don’t see it,” continued Koepka.
McIlroy, 30, claimed that he used a rivalry mentality to see off the American at the season-ending Tour Championship in August.
Four weeks earlier, Koepka had comprehensively outplayed McIlroy to win the World Golf Championship event in Memphis and the Northern Irishman said that he had been determined to avenge that defeat in the PGA Tour finale.
“He Koepka talked about trying to be the dominant player in the game … and I thought: ‘He’s going to have to go through me first’,” said McIlroy after his East Lake triumph.
“If that’s both of our mentalities going forward, I think that’s good for the game.”
In addition to successfully defending the US PGA title, Koepka was also runner-up at the Masters and US Open and shared fourth place at the Open Championship, with McIlroy’s best major finish in 2019 an eighth place at the US PGA.
The Ladies European Tour will continue to be a “feeder school” for the LPGA Tour despite plans to close the financial gap between them, according to LET chairman Marta Figueras-Dotti.
This year’s American LPGA has a prize fund of approximately £55m, compared with around £12m on the LET.
Figueras-Dotti told BBC Sport: “We are moving forwards slowly and the Solheim Cup win has helped.
“The LPGA needs a strong LET; we can help each other and make both strong.”
Spaniard Figueras-Dotti won the Women’s British Open as an amateur in 1982 and then spent one year as a professional on the LET before joining the LPGA Tour for 16 years until her retirement from playing in 2000.
The 61-year-old, speaking to the BBC as part of a special report on the health of the women’s game at last month’s Mediterranean Ladies Open, added: “The LET has never pretended to be like the LPGA, we are like a feeder school. It’s like the European Tour and the PGA Tour.
“But they need women’s golf. A lot of young women go to the US for college and they stay there. They play on the Symetra Tour [the development tour of the LPGA] – 17% of the players on that tour are European.
Figueras-Dotti is ambitious for the LET though. “We have great plans for next year,” she said.
“I dream big and I would like to see 40 events. If we reach 25-27 next year that would be wonderful.
“We want to create a better environment for the European based players, for them to make a living.”
The LET, which had dropped from staging 28 events a decade ago to 15 last year, is back to 20 this year, half of which were majors or co-sanctioned with other tours. The LPGA has 32 events for 2019.
But while the minimum prize money per tournament for LPGA events is $1.3m (£1m); the highest for an LET event was $500,000 (£395,000)
The current disparity in prize money means the leader of the LPGA money list, South Korea’s Ko Jin-young, has earned £2.1m in 2019, around 10 times more than her LET counterpart Carlota Ciganda, who has won £222,414.
The 100th top-earner on the LET is Trish Johnson with £7,840. In comparison, Mariah Stackhouse, who is 100th on the LPGA Tour list, has won £103,677.
“It’s really hard to play well if you don’t have many tournaments. The LPGA is so strong, so it’s hard to play here.”
‘We need to build on Solheim Cup win’
Scotland’s Catriona Matthew, who captained the victorious Solheim Cup team at Gleneagles in September, has played on both tours since 1995 and believes “the LET is healthy and will go from strength to strength” but needs to build on the “spectacle of the Solheim Cup and how it finished” like the women’s World Cups in football, cricket and netball.
She added: “It was a huge boost for women’s golf and hopefully a stepping stone for more sponsors and more events next year.”
It is a view echoed by England’s Meghan MacLaren, although she understands why sponsors are perhaps reluctant to get involved.
“People are talking about the Solheim Cup, the media are more interested. Look at women’s football. Big companies are involved and it’s opened up the market,” said the 25-year-old, who has won two LET events.
“The biggest disparity is what you can get personally. I understand sponsors have that value [in the men’s game] because it’s seen on television every week and we can’t offer that. But if we did, our value would go up.
“It’s difficult for the younger players to break through and make a career.
“There used to be more events. Look at the US, that is thriving, but we are starting to move in the right direction. Things are moving – it could be different this time next year.”
MacLaren finished joint 32nd in Spain, winning £2,333. But the vast majority of the money will have been spent on travel, accommodation and food, with many of the players choosing to share houses for the week and cook for each other to help keep costs down.
“We can see career earnings on a website, but that’s a far higher number than has gone in my bank account.
“You’ll spend on food and accommodation and flights, and then there’s money for personal development.
“A lot of girls will be pulling their own trolley, it would be nice to have a caddie.”

Men and women will compete against each other for one trophy at a new event to be hosted by Swedish golfers Henrik Stenson and Annika Sorenstam next year.
The Scandinavian Mixed is co-sanctioned by the European Tour and Ladies European Tour and will feature 78 men and 78 women in its field.
The event, with a total prize fund of 1.5 million euros (£1.3m), will count towards world rankings.
It will take place from 11-14 June at Bro Hof Slott in Stockholm.
As well as counting towards world rankings, Race to Dubai points and Ryder Cup points will be available to the men, and Order of Merit points will be on offer for the women.
“I’m delighted to host the Scandinavian Mixed alongside Henrik in Sweden for the next three years,” said Sorenstam, who retired from competitive golf in 2008 after winning 10 majors.
“Bringing women and men together in a combined tournament is exciting for fans in Sweden and for the global game as we continue to showcase golf is a game for everyone.”
Women compete against men at the GolfSixes team event, while women’s tournaments run concurrently with men’s events at the Trophee Hassan in Morocco and the Vic Open in Australia, but this will be the first time they have competed against each other in a full-field format.
Stenson, 42, the 2016 Open champion and five-time Ryder Cup player, has committed to play the event for the first three years, while Sorenstam, 49, will play in the tournament pro-ams.

Austrian Bernd Wiesberger moved to the top of the Race to Dubai list after winning the Italian Open by one shot.
The 34-year-old rises to a career-best 22 in the world rankings after a bogey-free six-under 65 for a 16-under total.
England’s Matthew Fitzpatrick led since the second round but had a double bogey at the ninth and was second after a 69, with Scot Robert MacIntyre tied fourth.
Justin Rose took 14 fewer shots than in third round, his 64 leaving him seven under for a share of 15th.
Wiesberger began the final round three shots back but was at the top of the leaderboard into the back nine after four birdies in five holes, with Fitzpatrick taking seven at the ninth, having sent his tee shot out of bounds.
The Austrian holed from the back of the 12th green to save par, while Fitzpatrick missed a birdie chance from inside five feet at the 11th.
Fitzpatrick, putting with the flagstick in, saw his eagle chance from 10 feet at the 17th out spin out of the cup and he could only par the final hole as Wiesberger celebrated his sixth European title, his third of the year after taking the Made in Denmark crown by a shot ahead of MacIntyre in May and winning the Scottish Open in a play-off in July.
“It’s been a great summer for me,” said Wiesberger, who missed the last seven months of the 2018 season with a wrist injury. “I’ve had a lot of good golf and shown a lot of progress after coming back from the last year.”
It was a fourth second-place finish of the season for Yorkshireman Fitzpatrick, who remains without a victory in 2019, having won a tournament each year since his maiden European triumph in 2015.
