The First Week at Home After Surgery: A Guide to Knee Replacement and Fracture Rehabilitation

The first postoperative week does not single-handedly determine the entire outcome of recovery, but it can significantly shape the quality of the weeks that follow. In this period, the goal is not to "do a lot of exercise." The real priorities are to begin safe movement while controlling pain and edema, recognize complications early, and plan the transition toward function without placing unnecessary stress on the joint or fracture site.

After total knee arthroplasty, fracture fixation, plate-and-screw surgery, or similar orthopedic procedures, the questions family caregivers ask are remarkably similar: How should we move the patient? Why will the knee not bend? Is swelling normal? Which exercises are appropriate? In which situations should we contact the physician immediately? This guide has been prepared to help patients and caregivers manage the first week at home in a calm, safe, and efficient way.

For many patients, the first week at home is dominated by the dilemma: "Should I move, or should I rest?" In reality, the correct approach is to establish a balance between immobility and overload. Too little movement may increase edema, joint stiffness, loss of muscle activation, and delay the return of function. Excessive effort, by contrast, may aggravate pain, trigger protective muscle guarding, and lead the patient to avoid exercise altogether in the days that follow. For this reason, the aim of the first week is controlled activation, safe transfers, circulatory support, early joint motion, and load management that respects the surgical or fracture site.

What should take priority in the first 72 hours?

In the first few days, the patient's main objective is not to "work like a marathoner," but to focus on pain control, circulatory support, swelling management, and safe positioning. After knee replacement, pain, bruising, and edema related to surgical trauma in the soft tissues are expected to some degree. Sources such as the NHS and AAOS emphasize the importance of regular but tolerable exercise, frequent position changes, and gradual walking in the early phase. The key distinction is this: the presence of pain does not necessarily mean that something is going wrong. However, pain that continues for hours after each movement, progressively worsens, or cannot be controlled with medication requires the program to be reassessed.

In fracture surgery, the approach during the first 72 hours varies somewhat depending on the diagnosis and fixation method. The stability of the operated bone, the surgeon's weight-bearing restrictions, the implant used, the wound condition, and any accompanying soft-tissue injury all shape the plan. For that reason, the idea that "everyone performs the same exercises after a fracture" is incorrect. Even so, the basic principles remain similar: support circulation, initiate safe transfers, prevent unnecessary stiffness in adjacent joints, and adhere to the protective rules set by the surgeon. Aggressive manual techniques or forceful joint movements should not be used until fracture stability has been confirmed.

Is it risky to get a postoperative patient into a car?

Getting a postoperative patient into a car is not automatically "risky," but if it is done without planning and with poor technique, it may increase pain, dizziness, movement anxiety, wound-site strain, and the risk of falling. The main point is not simply whether the patient enters the car, but whether the transfer is clinically appropriate, whether the patient can tolerate sitting, and whether the trip is truly necessary. In the first postoperative week, every transfer places an additional load on the patient. Therefore, if the planned outing is not medically essential, it is often better to avoid unnecessary car travel.

If transportation is necessary, preparation becomes critical. The height of the seat, the angle of entry and exit, the amount of knee flexion required, whether the patient can pivot safely, and the presence of a walking aid should all be reviewed in advance. After knee replacement in particular, a low car seat can increase pain and make standing up more difficult. For some patients, entering the car backward, sitting first, and then bringing the legs inside in a controlled way is safer than trying to step directly into the vehicle. However, this is not a universal rule. The surgeon's instructions, the patient's dizziness risk, weight-bearing status, and general endurance must all be taken into account.

A family caregiver should especially avoid pulling the patient abruptly under the arms or twisting the operated leg while "trying to help." Such attempts may provoke pain and loss of confidence. A physiotherapist can teach practical, patient-specific techniques for car transfers and other daily functional movements within the home.

Why does the knee not bend after surgery?

One of the most common complaints after knee surgery is: "The knee just won't bend." In many cases, this does not mean that the joint is "locked." Rather, it is usually the result of swelling, pain, tissue tension, reflex muscle guarding, fear, and insufficient quadriceps activation. The body becomes highly protective after surgery; when pain and edema rise, the patient may unconsciously resist bending. This creates a cycle: the patient avoids bending because it hurts, and the knee becomes stiffer because it is not moved.

Early limited knee flexion is not uncommon in the first postoperative week. The crucial issue is not to force the knee aggressively, but to create the right conditions for motion. Elevation, edema control, properly dosed active-assisted movement, short and frequent exercise sessions, and safe pain management together support improvement in range of motion. Very forceful stretching, repeated pushing "until it hurts," or comparing the patient to others may be counterproductive. Motion is not achieved through violence; it is restored through tissue tolerance, rhythm, and consistent loading.

However, if the knee remains nearly immobile, the swelling is increasing rapidly, the calf is markedly tense, there is sudden loss of movement, the wound is becoming more problematic, or severe pain is present, medical reassessment should not be delayed.

Is postoperative leg swelling normal?

A certain degree of swelling after surgery is often expected. Especially after knee replacement and lower-extremity fracture surgery, tissue trauma, reduced muscle-pump activity, immobility, and changes in local circulation can all increase edema. Therefore, mild to moderate swelling in the first days does not automatically mean that something is wrong. Nevertheless, swelling must be monitored rather than ignored.

Physiological postoperative edema tends to be distributed relatively diffusely, may lessen somewhat with elevation, and is generally accompanied by activity-related discomfort. By contrast, rapidly increasing, markedly asymmetrical, hot, tense, shiny, or intensely painful swelling requires caution. If swelling is accompanied by calf pain, tenderness, shortness of breath, sudden weakness, or a general deterioration in condition, urgent medical assessment is necessary because thromboembolic and other postoperative complications must be ruled out.

For edema management, medication alone is not enough. The rehabilitation program should also support venous return. Ankle pumps, short walking intervals within prescribed limits, appropriate limb elevation, breathing support, and avoiding long periods in the same position all help. Yet even seemingly useful measures should be tailored to the patient's specific procedure and surgical instructions.

How should exercise be planned in the first week?

In the first postoperative week, exercise should not be designed as a "performance test." The aim is to maintain circulation, reduce stiffness, re-establish muscle activation, and improve safe function. For this reason, short and repeated exercise bouts are often more effective than one long, exhausting session. A patient may tolerate three to six brief, low-intensity practice periods distributed across the day better than a single prolonged session.

Typical early exercises may include ankle pumps, quadriceps setting, gentle heel slides within tolerance, assisted knee flexion/extension as indicated, bed mobility practice, sit-to-stand training, and short bouts of walking. In fracture cases, however, which exercises are appropriate depends directly on weight-bearing status and surgical restrictions. The phrase "manual therapy after fracture" should also be interpreted carefully. In early fracture rehabilitation, direct and forceful intervention over the healing site is generally inappropriate; only carefully selected applications aimed at adjacent tissue mobility, pain modulation, edema control, and functional movement—when clinically justified—should be considered.

The patient's response after exercise is as important as the exercise itself. A mild increase in pain during or immediately after activity may be acceptable, but pain that persists for hours, increased swelling, a sense of instability, extreme fatigue, or complete avoidance of movement the next day usually signals that the intensity was excessive.

What should be considered when helping a postoperative patient walk?

Walking is one of the most reassuring yet most misunderstood milestones in the early period. Family members often ask, "How many days will it take before they can walk?" The more clinically relevant question is: How safe is the patient while walking, how much assistance is required, and what quality of walking is being achieved? Walking "a little" and walking "safely and usefully" are not the same thing.

Before beginning gait practice, the patient's blood pressure tolerance, dizziness risk, pain level, weight-bearing status, and use of assistive devices should be reviewed. Especially after a period of bed rest, the first attempt at standing may be accompanied by dizziness. If a caregiver panics in that moment and pulls the patient abruptly, the risk of falling rises. For this reason, the first walking sessions should be highly controlled, with the walking aid adjusted properly and the environment simplified. Rugs, cables, slippery surfaces, and poor lighting should be corrected before gait practice begins.

Another common mistake is to encourage the patient by saying, "Take bigger steps," "Bend more," or "Walk faster," even when the basic mechanics are not yet established. In the first week, quality should take priority over distance. Equal weight transfer, proper use of the walking aid, controlled turning, and safe sitting down are often more meaningful goals than simply walking farther.

What are common caregiver mistakes in the first week?

Family involvement is highly valuable in the early phase, but well-intentioned mistakes are also common. One of the most frequent errors is assuming that pain should be eliminated entirely and therefore limiting movement too much. Another is the opposite: pushing the patient to do more than they can tolerate because "if it hurts, it must be opening up." Both extremes are problematic.

Some caregivers attempt to bend the knee forcefully, massage the calf without indication, have the patient walk more than prescribed, or alter wound care based on advice from friends or social media. Others, frightened by pain, may discourage even appropriate movement and keep the patient almost completely immobile. Neither approach is safe. The correct model is guided, measured activity that respects the medical plan and is adjusted according to the patient's response.

Another common error is evaluating recovery day by day with excessive emotional intensity. One day the patient may feel better, and the next day pain may be higher. Early postoperative recovery is rarely perfectly linear. The key is not to interpret every temporary fluctuation as "failure," but to monitor the overall direction, functional gains, wound status, swelling pattern, and safety indicators together.

When should a physician be contacted immediately?

In the first week at home after surgery, some findings fall outside the expected course and should not be dismissed with "let's wait and see." Immediate medical consultation is warranted if there is shortness of breath, chest pain, fever, confusion, fainting, sudden wound drainage, foul odor, progressive redness, severe calf pain, marked asymmetrical swelling, new loss of movement, or pain that has suddenly become unmanageable.

Likewise, if the patient cannot stand at all despite previously being able to do so, develops increasing numbness, the foot becomes pale or cold, or there is a significant decline in general condition, the surgeon or relevant medical team should be informed promptly. Rehabilitation can only proceed safely when the medical picture remains stable.

What is the value of home physical therapy in the first postoperative week?

The first week is one of the periods in which home-based rehabilitation can be especially valuable, because treatment is shaped directly around the patient's actual daily environment. Bed height, bathroom access, chair transfers, walking pathways, car transfer strategies, caregiver education, edema control, walking aid use, and home exercise timing can all be planned in context. This often provides a more functional framework than a generic list of exercises.

In addition, the physical and emotional burden of transport in the first week can be considerable. For some patients, the effort required simply to leave the house may be almost as exhausting as the treatment itself. When rehabilitation is delivered at home, the patient's limited energy can be directed toward functional recovery rather than transportation logistics. Particularly in older adults, those with fracture surgery, patients after arthroplasty, and individuals with substantial pain during transfers, this may improve continuity and treatment tolerance.

However, home physical therapy is not automatically appropriate for every case. If wound monitoring is complex, medical instability is present, rapid physician reassessment is needed, or the patient requires services that are only available in a center, a hospital- or clinic-based plan may be safer.

If there is sudden worsening of pain, respiratory symptoms, wound-related problems, severe swelling, fever, or loss of function, professional medical evaluation should not be delayed.

FAQ

Is it normal to have swelling in the leg during the first week after surgery?

Some swelling may be expected after surgery, particularly after knee replacement or lower-extremity fracture surgery. However, rapidly increasing, markedly asymmetrical, very painful, hot, or shiny swelling requires medical evaluation.

Why will the knee not bend after surgery?

In many patients, limited knee flexion in the early phase is related to pain, edema, tissue tension, muscle guarding, and fear of movement. Aggressive forcing is not recommended. A structured and individually dosed rehabilitation program is safer and generally more effective.

Is it dangerous to get a postoperative patient into a car?

Not necessarily. The actual issue is whether the transfer is necessary and whether it can be performed safely. If the patient has not yet tolerated standing and sitting well, or if the trip is unnecessary, transport may be postponed.

Which exercises are safe during the first week after surgery?

This depends on the type of surgery and the physician's restrictions. Common early exercises may include ankle pumps, quadriceps setting, gentle assisted knee motion, bed mobility, sit-to-stand practice, and short bouts of walking. The program must be individualized.

Is manual therapy appropriate after fracture surgery?

Forceful intervention over the healing fracture site is not appropriate in the early phase. Only carefully selected techniques aimed at adjacent tissue mobility, edema control, pain management, and functional support should be considered, and only when clinically indicated.

When should we contact the doctor urgently in the first week?

Shortness of breath, chest pain, fever, fainting, foul-smelling wound drainage, progressive redness, severe calf pain, new loss of movement, or sudden deterioration in the general condition require prompt medical review.
