When facing the prospect of hip, knee or shoulder surgery, it’s natural to have plenty of questions. Whether it’s a hip replacement, knee arthroscopy, rotator cuff repair or shoulder replacement, patients often share similar concerns about timing, recovery, and getting back to daily life.
Dr. Oliver Khoo, Orthopaedic Surgeon in Sydney, often hears the same five questions in his consultations. Below, he answers them in detail, helping you better understand what to expect before and after surgery.
Many patients wonder whether they should “wait it out” or move forward with surgery.
In general, surgery is usually considered when:
Dr. Khoo often reassures patients that surgery isn’t always the first option. For example, some knee problems respond well to physiotherapy and strengthening programs. Similarly, certain shoulder injuries may improve with rest and injections. However, if pain is severe, quality of life is affected, or mobility is significantly limited, surgery may provide the most reliable long-term improvement.
Tip: The “right time” varies for every patient. Discuss your symptoms openly with your surgeon so they can recommend whether surgery is appropriate now or if conservative measures should continue.
Recovery is one of the biggest concerns patients have. While every individual heals differently, there are some general timeframes:
It’s important to understand that recovery doesn’t mean “doing nothing.” Gentle movement, physiotherapy, and adherence to post-operative instructions all help speed up progress.
Driving is a practical concern, especially for those who rely on their car for work or family commitments.
Insurance companies generally expect that a patient has medical clearance before returning to driving. Dr. Khoo advises his patients not to rush this step, as safe reflexes and mobility are crucial behind the wheel.
The answer depends heavily on the type of surgery and the nature of your job.
A gradual return—sometimes part-time at first—helps ease the transition back to full duties. Dr. Khoo works with patients and employers to create realistic return-to-work plans.
Patients often want to know how they can actively contribute to a smoother recovery.
Key strategies include:
Dr. Khoo often reminds patients that recovery is a partnership: the surgeon’s work inside the operating theatre, combined with the patient’s commitment afterwards, leads to the best results.
Aside from the “top five,” here are a few additional questions patients frequently ask:
Will I need a walking aid?
After hip and knee replacement, many patients use a walking frame or crutches initially, usually transitioning to a cane before walking independently.
What about pain after surgery?
Modern pain management techniques—including nerve blocks, medications, and physiotherapy—make recovery far more comfortable than in the past.
Are there risks?
As with any operation, risks exist. These may include infection, stiffness, or blood clots. Your surgeon will discuss these with you in detail before your procedure.
1. Can I travel after surgery?
Short car trips are usually possible within a few weeks, but long flights should be delayed until your surgeon advises. Blood clot prevention is especially important for air travel.
2. Will I set off airport security alarms with a joint replacement?
Joint implants may trigger metal detectors. Patients are usually advised to carry a medical note confirming the presence of an implant.
3. Can I kneel after knee replacement?
Some patients can kneel after recovery, but others find it uncomfortable. It does not usually damage the implant, but comfort levels vary.
4. Will my joint replacement last forever?
Modern implants are designed to last 15–20 years or longer, but factors like activity levels, weight, and overall health can influence longevity.
5. Can I return to sport after surgery?
Low-impact activities such as swimming, cycling, and golf are usually encouraged. High-impact sports, such as running or competitive contact sports, are generally discouraged to protect the joint.
