FAQs: Knee Surgery

Will I need a brace or crutches after surgery?

This depends on the type of surgery. After procedures like ACL reconstruction or meniscal repair, a knee brace may be used to protect the repair and control movement during healing. Crutches are commonly used in the early stages to offload the knee. For simpler procedures like a meniscectomy, they may not be necessary beyond the first few days.

Can cartilage damage heal without surgery?

In most cases, cartilage has very limited ability to heal on its own due to its poor blood supply. However, symptoms from smaller injuries can sometimes settle with physiotherapy, offloading the joint, and injections. Surgery may be recommended if symptoms persist or the defect is larger or interfering with knee function.

Is robotic-assisted knee replacement safe?

Yes, robotic-assisted surgery is a well-established and safe technique. It enhances the accuracy of implant positioning, but your surgeon remains fully in control at all times. The robotic system is used to assist, not replace, the surgical decision-making process.

Will I be able to kneel after a knee replacement?

Some patients are able to kneel after surgery, but others may find it uncomfortable due to sensitivity around the scar or the front of the knee. While it is generally safe to kneel once fully healed, it may feel awkward initially, and patients are encouraged to ease into it gradually.

How long will my knee replacement last?

Modern knee implants typically last 15 to 20 years or more, depending on activity levels, weight, and overall joint health. Robotic-assisted techniques and precise alignment may help improve the longevity of the implant.

When can I return to sport or the gym after surgery?

Low-impact activities like walking, cycling, and swimming are usually encouraged after recovery. Higher-impact sports may be limited depending on the type of surgery and your surgeon’s guidance. Patients undergoing ACL reconstruction or cartilage procedures often return to sport between 6 and 12 months, while those with joint replacements are advised to avoid high-impact activities like running or jumping long term.

Is physiotherapy important after knee surgery?

Yes, physiotherapy is a key part of recovery. Whether you’ve had a minor procedure or major surgery, a tailored rehabilitation plan helps restore strength, movement, and confidence in your knee. Compliance with your physiotherapy programme often has a direct impact on the success of your outcome.

Can I avoid surgery if I have a knee injury or arthritis?

In many cases, early intervention with physiotherapy, weight management, activity modification, and injections can help manage symptoms and delay the need for surgery. However, if pain and dysfunction persist despite these measures, surgery may be the most effective long-term solution

Is knee arthroscopy painful?

Arthroscopy is generally well tolerated. Patients may experience mild pain, swelling, or stiffness for a few days after the procedure, which is usually managed with ice, simple painkillers, and early movement exercises. Most people recover faster than with open surgery.

How long does knee arthroscopy take?

The procedure typically takes between 20 to 45 minutes, depending on what needs to be done. It is usually performed as a day case, meaning you can go home the same day.

What is the recovery time after knee arthroscopy?

Most patients are able to walk the same day or the following day. Return to work and normal activities varies, office-based workers may return within a few days, while more physical jobs may require a few weeks. Full recovery, especially after more involved procedures like a meniscal repair, may take several weeks to months with physiotherapy.

Will I need physiotherapy after the procedure?

Yes, physiotherapy is often recommended after arthroscopy to help restore strength, flexibility, and control of the knee. The extent and duration of physiotherapy will depend on what was treated during surgery.

Are there risks with knee arthroscopy?

As with any surgery, there are some risks. These include infection, bleeding, blood clots, stiffness, or ongoing discomfort. However, complications are uncommon, and the procedure is considered very safe when performed by an experienced surgeon.

Is knee arthroscopy a cure for arthritis?

Arthroscopy is not a cure for advanced arthritis. However, in selected cases of early arthritis or mechanical symptoms (such as catching from loose cartilage or meniscal tears), it can help reduce discomfort and improve function. For more advanced arthritis, other treatments may be more appropriate.

FAQs: Hip Surgery

What is the difference between a standard and a robotic-assisted hip replacement?

In a standard hip replacement, your surgeon uses traditional instruments and experience to position the implant. In robotic-assisted hip replacement, advanced technology is used to create a 3D model of your hip and guide implant placement with exceptional precision. The surgeon is still in full control, but the robotic system helps enhance accuracy and consistency.

Is robotic-assisted surgery better than standard surgery?

Both types of surgery can provide excellent results when performed by an experienced surgeon. Robotic-assisted surgery offers potential benefits such as even more accurate implant positioning, and possibly quicker recovery. However, not all patients require robotic assistance—it depends on your anatomy, level of joint damage, and overall goals. Mr Sisodia’s team can offer guidance on this.

Will I have a quicker recovery with robotic-assisted surgery?

Some patients may experience a faster return to mobility and less discomfort in the early weeks following robotic-assisted surgery. This can be due to more precise implant alignment and less soft tissue disruption. However, recovery time still varies between individuals and depends on factors like overall health, physiotherapy, and adherence to post-operative advice. 

Is robotic surgery done by a robot?

No. The robot does not perform the surgery. Mr Sisodia is fully in control of the surgery at all times. The robotic system is a highly advanced tool that assists in pre-operative planning and intra-operative precision, helping Mr Sisodia make well-informed, real-time decisions.

Am I a candidate for robotic-assisted hip replacement?

Many patients are suitable, especially those with complex hip anatomy or specific alignment concerns. After a full clinical assessment and review of your imaging, I will advise you on whether robotic-assisted surgery is the most appropriate option for your case.

How long does a hip replacement last?

Modern hip replacements are designed to last well over 15 years. Longevity depends on several factors, including implant type, surgical technique, patient activity level, and bone quality. Robotic-assisted surgery may improve long-term outcomes through more precise positioning of components.

Is robotic-assisted surgery better than standard surgery?

Both types of surgery can provide excellent results when performed by an experienced surgeon. Robotic-assisted surgery offers potential benefits such as even more accurate implant positioning, and possibly quicker recovery. However, not all patients require robotic assistance—it depends on your anatomy, level of joint damage, and overall goals. Mr Sisodia’s team can offer guidance on this.
