Knee Surgery Recovery Time: How To Plan For Your Knee Surgery

Posted on September 2nd, 2026 9/2/26

A doctor has just recommended you have knee surgery. Whether you’ve been managing knee pain for years or are meeting an orthopedic surgeon for the first time, you probably have a lot of questions. “How long is recovery from knee replacement surgery? What do I need to do before surgery? When can I get back to the activities I love?”

You want to know what to expect and how long it will take to resume your regular life. Here’s what you need to know to prepare for a successful procedure, including how to plan for your knee surgery recovery time, when to expect to return to work, and what you can do to help yourself heal faster.

Types of Knee Surgery

When knee pain makes it hard to walk, do daily activities, or enjoy sports, it’s time to seek treatment and medical advice. Most orthopedic specialists will start with conservative treatments before recommending surgery, like physical therapy or ice and heat therapy. If these non-invasive treatments fail to provide relief, surgical options are considered. While there are many medical conditions and injuries that affect the knees, most damage can be addressed through one of the four most common types of knee surgery:

For patients considering partial or total knee replacement, it’s also worth knowing that MOSH offers robotic-assisted surgery, one of the most significant advances in joint replacement care in recent years. Robotic-assisted surgery allows MOSH surgeons to plan and perform your procedure with a level of precision tailored to your unique anatomy, which can mean less post-operative pain and a faster return to the activities you love.

Seeing an Orthopedic Surgeon

If your primary care doctor recommends a surgical procedure on your knee, they will likely refer you to an orthopedic surgeon. Orthopedic surgeons, like those employed at MOSH, are expert doctors specializing in the musculoskeletal system. This first appointment is an important one because it’s a conversation, not just an exam. Come with questions. Your orthopedic surgeon is there to understand you and get a complete picture to help you find the right path forward. Your visit with an orthopedic surgeon may include the following:

A patient medical history
A review of medications
A physical exam that includes checking your knee’s range of motion, how much pain you are having, and how your daily activity changed since the pain began
Imaging of the knee
Routine blood tests
A discussion of surgical options and the recovery process

Planning for a Successful Knee Surgery

Once your knee surgery is scheduled, you will be given a list of things you need to do to prepare for surgery. The most successful surgeries start with a commitment to follow pre-surgery instructions and a well-thought-out knee surgery recovery plan.

Your Knee Surgery Plan: Before Surgery

Before surgery, your orthopedic team will provide you with clear instructions on how to prepare for the procedure. These preparations usually start weeks before the procedure to the day of surgery. They may even include instructions for weeks after surgery. It is very important to follow your doctor’s orders and ask questions if necessary.

Typical pre-operative instructions include:

Medication adjustments: your doctor may prescribe pre-surgery medications such as antibiotics or blood thinners, or may ask you to pause certain daily medications for a period of time.
Physical therapy: a pre-op PT appointment will allow a physical therapist to get a baseline reading on the function and impairment of the injured knee joint or to give you pre-op, low-impact exercises to strengthen the leg.
Lifestyle changes: doctors commonly recommend cessation of tobacco, caffeine, and alcohol.
Education: you will likely receive written instructions, including ‘day of’ surgical requirements from your orthopedic surgeon. At MOSH, patients are given a booklet with information on the surgery and a before and after knee surgery care plan. MOSH offers a “Joint Effort” class. These classes provide all the surgical information you will need and allow you to meet your surgical team, ask questions, and see where your surgery will take place.
Find a support person: you will need help before and after the procedure with walking, driving, and daily tasks. A support person (also known as a coach) can help you prepare and keep you safe during recovery.
Prepare your home: your living space needs to be prepped for your post-surgical recovery. You and your support person need to remove loose rugs, clear walkways of clutter and obstructions, add nightlights, and rearrange furniture, so there is enough room for you to move around with your assistive devices. You will want to ensure the items you use the most are nearby. You and your coach will also need to prepare your bathroom and establish procedures for showering and bathroom use. Preparing and freezing meals ahead of time is also recommended.

Knee Surgery Recovery Times

The pre-operative planning process also includes understanding your recovery timeline. Each person’s recovery depends on their surgery, the type of damage repaired, and their physical and mental condition at the time of the procedure. However, each surgery does have general guidelines you can use to plan your post-surgical time.

Knee Osteotomy

A knee osteotomy helps with the pain and damage from osteoarthritis. The procedure can help shift weight off the damaged part of the joint by realigning leg and knee bones. A knee osteotomy may delay the need for a total knee replacement.

You can plan on two to four days in the hospital after surgery. You will likely use a continuous passive motion machine under your knee to help keep the joint flexible. You will need crutches and a knee brace to stabilize the joint for several weeks. You will also need physical therapy and joint rehabilitation to regain strength and function. You can expect to return to a sedentary job four to six weeks after surgery and fully recover in three to six months.

Knee Arthroscopy

Arthroscopic knee surgery is minimally invasive, using small incisions and a tiny camera to look inside the body. Arthroscopy is advised for various knee problems, especially for injuries to the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and meniscus.

Knee arthroscopy is usually an outpatient procedure, which means you will be going home the same day. Because this procedure is less invasive, the knee surgery recovery period is much shorter than other surgeries. You might get a referral to a PT or an exercise program to keep the knee flexible in your discharge instructions. You will likely need crutches for a few weeks to help keep weight off the joint and to assist with walking. A knee brace may be necessary for several weeks.

Most people can return to a desk job a week or two after surgery but will need accommodations to get to work because you likely won’t be able to drive or use stairs. In one to two months, you can return to normal activities, and full recovery takes several months to a year, depending on the complexity of the procedure.

Partial or Total Knee Replacement

Partial and total knee replacement are among the most common knee procedures performed today and carry the longest recovery times. Patients with severe arthritis or degenerative joint diseases can benefit from these procedures.

After a total knee replacement surgery, you will likely spend one to three days in the hospital to recover, begin physical therapy, and use a continuous passive motion machine. A mobility device like a wheelchair or crutches will be needed for one to three weeks, with the ability to walk by yourself in four to eight weeks. If your job is sedentary, you can resume work in four to six weeks and more active employment in three months. You will likely have a full recovery in six months to a year for a total replacement.

A partial knee replacement surgery takes a couple of hours, and you will likely stay in the hospital for one to three days. You can put weight on your knee immediately, and you will probably use a continuous passive motion machine and start physical therapy while in the hospital. You can expect to walk without using an assistive device like a cane or walker in three to four weeks. You should recover almost full function in six to eight weeks.

For patients undergoing partial or total knee replacement, Mako® robotic-assisted surgery at MOSH offers the additional benefit of implant placement precision built around your specific anatomy, which supports better alignment, less post-operative discomfort, and a more confident recovery.

Your Knee Surgery Plan: After Surgery

Post-operative instructions will be provided either as part of your pre-operative planning or in your discharge paperwork. Following these instructions carefully is essential to avoiding complications and ensuring your knee heals correctly.

After your procedure, you may need to:

Watch for signs of infection or blood clots
Ice the area to manage swelling
Wait three to seven days to shower if your surgeon did not use waterproof dressings
Follow all exercise and physical therapy instructions
Keep your knee straight (don’t use a pillow underneath the knee)
Adjust medications as directed
Avoid high-impact activities, stairs, and driving during the early recovery period

How to Decrease Knee Surgery Recovery Time

While recovery times vary from person to person, there are additional things you can do to speed up your recovery and keep yourself healthy. Losing weight, eating healthy, and keeping a positive attitude have been shown to help patients recover faster. Some more tips for a quicker recovery include:

Adhering to the instructions given to you by your doctor and rehabilitation team. Keep physical therapy and follow-up appointments and wear the knee brace if given one. Walk when you are cleared to do so, and do it frequently to prevent the knee and legs from becoming weaker.
Give yourself time to heal. Rushing back to your normal routine will not speed up your recovery. Rest when you need to. Prioritize restorative sleep.
Recruit help. You already have your support coach, but could you use more help? Lean on family and friends for tasks like grocery shopping, laundry, and household chores.
Eat healthy, well-balanced meals. Your body needs the right fuel to heal, and nutrient-dense foods are the best way to get the minerals and vegetables your body needs to heal. Focus on foods rich in protein, vitamins D and C, calcium, and iron. Try to avoid foods high in Vitamin K.
Avoid fall risks. Stay away from environments or activities that involve rapid changes of direction or uneven surfaces that could stress the knee during healing.
Stay positive. A constructive mindset has been shown to support better recovery outcomes. Patients who approach recovery with patience and optimism consistently do better.
