How Long Does Ankle Surgery Take?

Most ankle surgeries take between one and two hours of actual operating time, though the specific procedure matters enormously. A straightforward fracture repair averages around 75 minutes, while more complex reconstructions or fusions can push past two hours. What often surprises people is that the time spent on the operating table is only a fraction of the total time commitment on surgery day, and an even smaller fraction of the recovery timeline that follows.

Typical Operating Times by Procedure

Ankle surgery is not one operation. It is a family of procedures ranging from soft-tissue ligament repairs to bone fusions, and each carries its own time profile. The most common ankle surgery is open reduction and internal fixation, or ORIF, which is used to realign and stabilize broken bones with plates and screws. A large study of ankle ORIF procedures found an average operating time of about 76 minutes, though with wide variation depending on the complexity of the break.¹ A simple single-bone fracture might be done in under an hour, while a trimalleolar fracture involving all three parts of the ankle joint could take well over 90 minutes.

When surgeons use arthroscopic techniques for fracture repair, operating times tend to run longer. One comparative study found that arthroscopic-assisted fracture fixation averaged about 105 minutes, compared to roughly 94 minutes for traditional open surgery.² The extra time comes from the additional setup and the need to navigate the joint through a camera and small instruments rather than through a direct incision. The trade-off is usually smaller scars and potentially less tissue disruption.

Lateral ankle ligament reconstruction, the surgery done for chronic ankle instability after repeated sprains, is generally quicker. One study comparing arthroscopic and open approaches to ligament reconstruction found that the arthroscopic group averaged about 50 minutes of surgical time, while the open group averaged about 60 minutes.³ These are among the shorter ankle procedures because the work involves soft tissue rather than bone realignment.

Ankle fusion, which permanently joins the bones of the ankle joint to eliminate painful arthritis, sits at the longer end of the spectrum. A systematic review comparing open and arthroscopic fusion found that open procedures had longer tourniquet times by roughly 16 minutes, though the total operation time was not significantly different between the two approaches.⁴ Most ankle fusions run somewhere between 90 minutes and two hours. Total ankle replacement, where the joint is replaced with an artificial one, also tends to fall in that range or slightly longer, depending on the implant system used and the surgeon’s experience with it.

What Pushes the Clock Up or Down

The variation in ankle surgery duration is driven by a handful of factors. The fracture pattern is the biggest one. A single break on one side of the ankle is a fundamentally different operation from a complex injury involving both sides of the joint plus the back of the tibia. Each additional fracture fragment adds steps: more hardware, more reduction maneuvers, more X-ray checks during the procedure.

Your surgeon’s experience with the specific procedure also matters. Surgeons who perform a high volume of a particular operation tend to be faster, not because they rush but because their movements are more efficient and they encounter fewer surprises. This is particularly true for arthroscopic and minimally invasive techniques, which have a steeper learning curve. The arthroscopic fracture repair study that found longer operating times for the minimally invasive approach noted that the technique demands more technical skill in exchange for its cosmetic and soft-tissue benefits.²

Where the surgery takes place can affect the overall time as well. Research has found that ambulatory surgery centers tend to have shorter total operating room times and total facility times compared to hospital operating rooms for comparable procedures.⁵ This is partly because standalone surgery centers have more streamlined scheduling and shorter gaps between cases. The actual cutting-and-fixing time does not change, but the preoperative and room-turnover intervals are often shorter.⁶

Patient factors play a role too. Obesity makes surgical access harder and can add time. Pre-existing conditions like diabetes or peripheral vascular disease don’t necessarily lengthen the procedure itself, but they can complicate wound closure and may lead the surgeon to work more carefully around compromised tissue. In the ORIF study that found a 76-minute average, the standard deviation was nearly 37 minutes, reflecting the wide range of patient complexity and fracture severity the surgeons encountered.¹

Why Longer Operations Carry More Risk

Operating time is not just a scheduling concern. Longer procedures are independently linked to higher rates of surgical site infection and wound complications after ankle fracture fixation.¹ Every additional minute means more time the wound is open and exposed, more tissue drying, more retraction of soft tissues, and a longer period under tourniquet pressure.

Tourniquets, which surgeons inflate around the upper calf or thigh to create a bloodless field, are standard in ankle surgery. The concern has always been that prolonged tourniquet use might impair wound healing. One study specifically examined this question in complex hindfoot surgery and found that tourniquet times between two and three hours, at pressures up to 300 mmHg, were not associated with significant wound healing problems compared to shorter tourniquet durations. That provides some reassurance for the longer procedures, though surgeons still aim to keep tourniquet time as short as reasonably possible.

The relationship between time and complications is one reason why surgeons weigh the benefits of minimally invasive techniques carefully. Arthroscopic approaches may produce smaller incisions and less soft-tissue stripping, but if they substantially increase operating time, the net benefit for wound healing is less clear-cut. For experienced arthroscopic surgeons, the extra time is modest enough that the trade-off typically favors the minimally invasive approach. For less experienced hands, the calculus may differ.

The Full Surgery Day From Check-In to Going Home

When your surgeon tells you the operation will take about an hour and a half, that refers to the time from incision to closure. Your actual day at the surgical facility will be considerably longer. You will typically arrive one to two hours before the scheduled surgery start time. That window covers check-in paperwork, changing into a gown, placing an IV line, meeting the anesthesiologist, and receiving a nerve block if one is planned.

Peripheral nerve blocks have become a standard part of ankle surgery. A well-placed block can numb the foot and ankle for 12 to 24 hours, which means far less pain when you wake up and often a reduced need for opioid medications in the first day. The block itself takes 10 to 20 minutes to administer and another 15 to 30 minutes to take full effect, which is why it happens well before you are wheeled into the operating room.

After the operation, you will spend 30 minutes to two hours in the recovery room as the general anesthesia or sedation wears off. Nurses will monitor your vital signs, check on pain levels, and confirm that the nerve block is still providing adequate coverage. If you are being discharged the same day, you will need to demonstrate that your pain is under control, that you are not nauseated, and that you can safely use crutches or a knee scooter before you leave.

All told, most people should plan for a four-to-six-hour commitment on surgery day for an outpatient procedure. For inpatient cases, the surgical-day experience is similar, but instead of going home you will be moved to a hospital room afterward.

Outpatient Versus Overnight Stay

Whether you go home the same day or stay in the hospital depends on the procedure, your overall health, and increasingly on the trend toward outpatient surgery. A meta-analysis of surgically managed ankle fractures found that roughly 46% of patients were treated as outpatients and 54% as inpatients, though the outpatient share has been growing.⁷

The difference in facility time is dramatic. One study found that outpatients spent an average of about 7.5 hours at the facility, while inpatients averaged around 54 hours, or just over two days.⁸ The inpatient group in that study included more complex fractures and patients with medical conditions that warranted monitoring, which partly explains the longer stay. For a straightforward single-fracture fixation in a healthy person, same-day discharge is now common at many centers.

Ligament repairs and reconstructions for ankle instability are almost always outpatient procedures. You go home in a splint or walking boot the same day, and the surgical center typically calls you the next morning to check on your pain and any concerns. Ankle fusions and total ankle replacements are more likely to involve at least one overnight stay, though enhanced-recovery protocols are pushing some of these toward same-day or next-morning discharge as well.

Weight-Bearing After Ankle Surgery

The question people often care about more than the surgery itself is how long they will be off their feet. The answer depends heavily on the procedure and the surgeon’s protocol, and there is real disagreement among surgeons about the right approach.

For ankle fracture fixation, a survey of orthopaedic trauma and foot-and-ankle specialists found that the prescribed non-weight-bearing period ranged from about five weeks for a young, healthy patient with a simpler fracture to nearly eight weeks for older patients with comorbidities and complex trimalleolar fractures.⁹ The responses showed a high degree of variation from surgeon to surgeon, even for the same injury type. Medical status was actually a stronger predictor of how long surgeons kept patients non-weight-bearing than the fracture pattern itself.

There is growing evidence supporting earlier weight-bearing. A systematic review of 12 studies covering more than 1,800 patients compared early weight-bearing protocols, where patients started putting weight on the ankle within two weeks of surgery, to delayed protocols.¹⁰ The trend in the literature has been toward allowing earlier activity, though the specifics depend on fracture stability and fixation quality.

For lateral ligament repair, some surgeons now allow full weight-bearing in a walking boot from the first day after surgery.¹¹ This is a notable shift from earlier protocols that kept ligament-repair patients non-weight-bearing for weeks. The modified Broström repair, which is the most common procedure for chronic ankle instability, has proven sturdy enough in many patients to tolerate immediate loading in a protective boot.

For reconstructions that use tendon grafts rather than simply tightening the existing ligament, the timeline is more conservative. Rehabilitation protocols for ligament reconstruction commonly prescribe 12 to 20 weeks before returning to full activity, with substantial variation between surgeons.¹²

Returning to Sports and Full Activity

For active people, the real recovery benchmark is not when you can walk again but when you can run, cut, and jump without restriction. The timeline here varies dramatically based on what was injured and what was done to fix it.

After surgical ankle fracture repair in athletes, a systematic review found an average return-to-sport time of about 135 days, or roughly four and a half months. But the range was enormous: athletes with simple fractures came back much sooner, while those with bimalleolar or trimalleolar fractures sometimes took up to 720 days, or nearly two years.¹³ That upper end is the outlier, but it highlights how much fracture severity drives the recovery trajectory.

For professional athletes who undergo acute lateral ligament repair rather than fracture fixation, the timeline is shorter. One study of professional athletes found a median return to competitive sport of 77 days for isolated ligament injuries but 105 days when there was a concomitant injury, such as a bone bruise or cartilage lesion alongside the ligament tear.¹⁴ The difference was statistically significant, underscoring how much additional damage inside the joint can slow things down even when the primary surgery goes smoothly.

Syndesmotic injuries, the so-called “high ankle sprains” that disrupt the ligament connecting the tibia and fibula, tell an interesting story about competition level. A study of athletes who had suture-button fixation for syndesmotic injuries found that the overall average return to play was about 139 days. But college athletes came back in roughly 39 days on average, while NFL players took about 190 days.¹⁵ That difference likely reflects the higher physical demands and greater scrutiny in professional leagues, where team medical staffs may be more conservative about returning a valuable player before full recovery.

For ligament reconstruction patients who are recreational athletes rather than professionals, accelerated rehabilitation programs have shown promise. One study compared traditional post-operative cast immobilization for four weeks against an accelerated protocol that skipped the cast entirely after anterior talofibular ligament reconstruction with a tendon graft. Both groups ultimately did well, suggesting that motivated patients with good surgical fixation can safely move through recovery faster.¹⁶

When Timing Before Surgery Matters

One question people rarely think to ask is whether the time between injury and surgery affects outcomes. For ankle fractures that are displaced, the answer appears to be yes, at least in one important way. A study of displaced ankle fractures found that each hour of delay before the fracture was reduced, meaning the bones were pushed back into rough alignment, was associated with about 60% higher odds of soft tissue problems developing before surgery could happen.¹⁷ Blistering, swelling, and skin breakdown over the fracture site can force surgeons to delay the definitive operation until the soft tissues calm down, which paradoxically means even more waiting.

The reassuring finding from the same study was that the delay in reduction was not independently associated with higher rates of post-operative complications, re-operation, or longer hospital stays once the surgery did happen. The damage from delay is mostly to the soft tissue envelope, not to the surgical outcome itself. Still, if you sustain a visibly displaced ankle fracture, getting to an emergency department quickly for a reduction matters, even if the actual surgical repair is scheduled for days later.

For non-displaced fractures and elective procedures like ligament reconstruction, timing is less urgent. Chronic ankle instability surgery is almost always scheduled weeks or months after the decision to operate, giving you time to optimize your health, strengthen surrounding muscles, and arrange the logistical support you will need during recovery. There is no evidence that waiting a reasonable period for an elective ankle procedure worsens outcomes, and in many cases the pre-operative conditioning actually improves them.

Arthroscopic Versus Open Approaches

The choice between arthroscopic and open surgery affects not only the time in the operating room but also the recovery experience afterward. For ankle fusion, the meta-analysis comparing the two approaches found that while operating time was essentially the same, open fusion led to longer hospital stays by about a day and a half and had a lower rate of successful bone union.⁴ Infection rates and overall complication rates did not differ significantly between the two, which suggests the advantage of arthroscopic fusion lies mainly in faster discharge and more reliable fusion rather than in fewer complications per se.

For ligament reconstruction, the arthroscopic approach not only shaved about 10 minutes off the surgical time but also produced better functional scores and a faster return to sports, with the arthroscopic group getting back to athletic activity about three weeks sooner.³ The proposed reason is that the arthroscope allows the surgeon to place bone tunnels more precisely, leading to a reconstruction with better biomechanics from day one.

Not every patient or every ankle is suited to arthroscopic surgery. Severe deformity, significant bone loss, or very complex fracture patterns may require the broader visualization that an open approach provides. If your surgeon recommends an open procedure, it does not mean you are getting inferior care. It often means the anatomy demands it. The best outcomes come from matching the surgical approach to the specific problem, not from defaulting to whichever technique sounds more advanced.
