When an older person has just had hip fracture surgery, what the family cares about most is when the patient can put the foot down and walk. A deep-rooted worry often follows: that doing too much will make the screws in the body move, and that it would be safer to stay in bed a few days longer.
To answer this directly: in most cases, the earlier the patient bears weight within what can be tolerated (WBAT), the better the rehabilitation result. A systematic review shows that the group allowed free weight-bearing had lower long-term mortality than the restricted weight-bearing group (RR 0.67, low certainty of evidence), with no significant difference in complications, repeat surgery or length of hospital stay (J Clin Med, 2026). In other words, the instinct that more rest is safer is the wrong way round in hip fracture rehabilitation. The sections below go through what WBAT means, how the timing of putting the foot down differs between extracapsular and intracapsular fractures, how far the current medical evidence goes, and why patients so often limit their own activity too much.
What “weight-bearing as tolerated” (WBAT) means
The WBAT that a doctor writes in the notes stands for weight-bearing as tolerated. In the plainest terms: as long as the pain is acceptable and both feet stand steadily, the patient can stand and step, and pain and balance are the natural limiters, with no need to wait until the wound has completely healed before daring to put the foot down. This is also why many patients with extracapsular fractures are allowed to bear weight straight away after internal fixation or joint replacement.
As for when to start putting the foot down, the position of international guidelines is quite consistent: get moving as early as possible after surgery. The UK NICE guideline states that older people with hip fracture should have physiotherapy the day after surgery and be out of bed every day after that (NICE CG124). The putting down of the foot here does not mean the older person walks alone. It means starting with standing up with support and stepping on the spot, in a safe setting with the physiotherapist steadying the patient and a walking frame to lean on. Real safety comes from getting moving early with a professional keeping watch, and not from waiting until the patient feels steady before moving.
Remember a basic principle: the level of weight-bearing is decided by the orthopaedic doctor according to the fracture and the type of surgery, but how to progress within the same level (for example from standing with support to walking with a frame) is adjusted gradually by the physiotherapist according to the older person’s actual response each day. Once this division of roles is clear, the patient will not lie in bed for fear of the bone moving.
Timing of weight-bearing in extracapsular and intracapsular fractures
Although both are called hip fractures, the timing of putting the foot down after surgery can differ greatly. The key lies in the site of the fracture and the way it was fixed, which is also what families often find most confusing.
- The site is outside the joint capsule, with a better blood supply and better conditions for healing
- Mostly fixed with an intramedullary nail or a dynamic hip screw, which is mechanically more stable
- Clinically, immediate full weight-bearing (WBAT) after surgery is often allowed
- Getting the foot down early suits this type of fracture especially well
- The site is inside the joint capsule, the blood supply is more fragile, and there is a risk of non-union or displacement
- If fixed with screws or a sliding screw (rather than replacement), the fracture surface is more sensitive
- The orthopaedic team sometimes prescribes a period of protected or partial weight-bearing to give the bone longer to heal
- The exact limit and its length must follow the surgeon’s instructions
One point is worth noting. If a femoral neck fracture is treated with joint replacement (hemiarthroplasty or total hip replacement) instead of internal fixation, clinical consensus generally allows immediate full weight-bearing after surgery. Because an artificial joint has been put in, there is no risk of the fracture surface moving. The idea that every intracapsular fracture needs protected weight-bearing is therefore not accurate. The real dividing line is whether there is a piece of the original bone that needs time to heal. Which operation the older person actually had, and how much weight the leg can take, are stated clearly in the operation report at discharge and in the surgeon’s weight-bearing instructions, and it is most practical to give these documents to the physiotherapist.
Rehabilitation after an extracapsular fracture
- This type of fracture has a good blood supply and secure fixation, so the conditions for healing are fairly good
- Most patients can bear weight as tolerated (WBAT) at once, and early weight-bearing helps to reduce the complications of bed rest
- The focus of rehabilitation is to stand early, improve walking ability and keep training the leg muscles
Rehabilitation after an intracapsular fracture (internal fixation)
- The site of this type of fracture is more sensitive, and a period of protected weight-bearing may be needed
- The patient must strictly follow the level and length of weight-bearing set by the doctor
- Even when weight-bearing on the leg is limited, the arms, the good leg and breathing exercises must still go on as usual
The medical research on early weight-bearing and its limits
How solid is the medical basis for the claim that early weight-bearing is better than late weight-bearing? The data in support of this direction come first, followed by the limits of this evidence.
The three sets of data above all come from the same systematic review and pooled analysis published in 2026 (J Clin Med, 2026). The direction of the results is quite clear: the group allowed to bear weight freely had lower long-term mortality, and the families’ greatest worry, whether early weight-bearing raises the risk of repeat surgery or complications, did not show up in the data. This agrees with clinical observation: getting out of bed early effectively reduces the complications of bed rest such as pneumonia, blood clots, pressure sores and loss of muscle. In the Hong Kong healthcare setting this matters even more. The one-year mortality of Chinese older people in Hong Kong after hip fracture is about 16.8%, and the earlier the operation, the better the outcome (Liu et al. 2017). Rather than worrying about doing too much, it is better to follow the safer recovery path of early surgery and early weight-bearing.
Another point that is often overlooked is that walking early does not mean the rehabilitation course is over. A randomised controlled trial extended the rehabilitation period to about six months and added progressive resistance training, and the older people in it showed more significant gains in physical function and strength than those in the group that did only low-intensity home exercises (Binder et al. 2004). In other words, safe weight-bearing is only the first step, and the follow-on training of leg strength decides how far the older person can finally walk. In Hong Kong, rehabilitation beds in public hospitals have always been tight, and after discharge older people often live in tenement buildings without a lift or in small flats, so going out for follow-up is very inconvenient. This gap after discharge is exactly when a home rehabilitation service is most needed to take over.
We must also point out the limits of this body of evidence. The overall GRADE certainty of the research is low, and most of it is observational in design, so it may not fully rule out selection bias (patients who are healthier and more mobile to begin with are more likely to be allowed unrestricted weight-bearing). The correct reading is therefore not that everyone should bear weight without limit. It is that, provided the fixation is secure and the orthopaedic doctor allows it, early weight-bearing is a reasonable and safer default. The current evidence supports this approach, but it still has to be assessed case by case. For how much walking ability can be regained in the long run after hip fracture, and how to assess the outlook, see outlook and expected recovery.
How to tell whether to carry on moving or stop and seek medical help
Clinically, one phenomenon is very common. The doctor has clearly written WBAT (weight-bearing as tolerated is allowed) on the discharge papers, but the older person and the family, from fear that the screws will move, fear of pain and fear of falling again, cut activity right down. Even holding a walking frame, the patient does not dare to take a step and sits on the edge of the bed all day. At home assessments, the most common problem is not too much activity but the patient being able to move yet limiting himself or herself too much out of fear, so that muscle strength and walking confidence both fall away quickly.
The decline in physical function (deconditioning) caused by not daring to move for fear of pain and falls is much the same as the decline brought by long bed rest, and the direction for rebuilding is covered in rehabilitation after a long hospital stay. After either internal fixation or joint replacement, patients also often face the same problem of weak hip abductors. A hip-swaying, limping gait does not necessarily mean the bone is not yet secure, and often it is just that the strength of gluteus medius has not recovered. To break out of this over-cautious position, the key is to tell which situations really need the patient to stop and which come only from fear.
| Should carry on progressing | If the doctor has stated that weight-bearing as tolerated (WBAT) or full weight-bearing is allowed, there is only mild acceptable soreness on standing, and people and the walking frame are giving firm support, then still not daring to step does more harm to health. |
| Should stop at once and seek professional advice | Sharp severe pain at the site of the wound, a sudden inability to bear any weight, unusual noises from the joint, an operated leg that is clearly shorter or turned outwards, or fever, redness and swelling can be warning signs of displaced internal fixation or wound infection, and the patient must seek medical help at once. |
When is a physiotherapist needed? When the older person’s legs hurt so much on putting the foot down that the patient cannot stand steadily, when mobility has clearly gone backwards, when the patient is so afraid of bearing weight that he or she refuses to move, or when the family does not even know the level of weight-bearing the orthopaedic doctor has instructed, they should stop guessing. Nova Health’s registered physiotherapists, through physiotherapy at home, can visit to check the weight-bearing arrangement the doctor instructed, demonstrate safe standing and walking-frame techniques, and adjust the training intensity gradually according to the older person’s body response each day, so that early weight-bearing follows the doctor’s instructions strictly without being too cautious. Because older people with hip fracture are very likely to fall again, preventing falls while raising the amount of activity is a topic of its own.
