What to expect during and after Knee Surgery

Dr. Lehman performs a detailed evaluation, including a physical exam and imaging, to determine the best surgical option for your needs. If surgery can be avoided, Dr. Lehman may recommend suitable regenerative medicine therapies.

You’ll receive guidance on preparing for surgery, including medication instructions, lab work, and pre-op physical therapy if recommended or required.

Most surgeries are performed outpatient using arthroscopic techniques. Complex surgeries like knee replacement may require a short hospital stay.

You’ll begin walking (with assistance) shortly after surgery. A custom rehab plan supports your healing with milestones over weeks to months. Most patients regain significant function within 6–12 weeks, depending on the procedure.

Frequently asked questions

There are several types of knee surgery, each designed to address specific conditions or injuries. Common procedures include:

  • Arthroscopic Knee Surgery: A minimally invasive technique used to repair cartilage, remove loose bodies, or smooth damaged tissue.
  • Meniscus Repair or Removal: Treats torn cartilage in the knee that can cause pain or locking.
  • ACL Reconstruction: Replaces a torn anterior cruciate ligament using a graft, often needed after sports injuries.
  • Cartilage Restoration: Techniques like microfracture or autologous chondrocyte implantation to regrow cartilage.
  • Patellar Realignment: Corrects kneecap tracking issues or instability.
  • Tendon Repair: Reattaches torn quadriceps or patellar tendons to restore knee extension.

Dr. Lehman will recommend the best procedure based on your diagnosis, activity level, and long-term goals.

You may be a good candidate for knee surgery if you experience chronic knee pain, swelling, or instability that hasn’t improved with non-surgical treatments like physical therapy, bracing, or injections. Ideal candidates include:

  • Individuals with significant cartilage damage or meniscus tears
  • Athletes with ligament injuries such as ACL tears
  • Athletes with ligament injuries such as MCL tears
  • Patients with advanced osteoarthritis affecting mobility
  • Those whose pain interferes with work, exercise, or daily life

Dr. Lehman will perform a detailed evaluation to determine if surgery is the best solution based on your symptoms, lifestyle, and long-term goals.

Preparing for knee surgery involves several key steps to ensure a safe procedure and smooth recovery. First, you’ll undergo a full medical evaluation, including blood work, imaging, and possibly an EKG, to confirm you’re cleared for surgery. Dr. Lehman will review your current medications and advise on any that should be paused, such as blood thinners. In some cases, pre-surgical physical therapy may be recommended to strengthen the muscles around your knee and improve post-operative recovery. It’s also important to prepare your home by creating clear walking paths, securing handrails, and planning meals in advance. Make sure to arrange for someone to drive you home and assist you during the first few days post-op. Finally, follow all pre-operative instructions closely, including fasting guidelines and what to bring on surgery day. Dr. Lehman’s team will walk you through every step to ensure you’re ready and confident heading into your procedure.

While some discomfort is expected after knee surgery, pain is typically well-managed with modern anesthesia and post-operative medications. During the procedure, you’ll be under regional or general anesthesia, so you won’t feel any pain. After surgery, you may experience soreness, stiffness, or swelling, especially in the first few days. Dr. Lehman’s team will provide a personalized pain management plan, including medications, icing, and activity guidance, to keep you comfortable throughout recovery. Most patients find that any temporary discomfort is well worth the long-term relief and improved mobility knee surgery provides..

Recovery time from knee surgery varies depending on the type of procedure and your overall health. For minimally invasive surgeries like arthroscopy or meniscus repair, many patients resume light activities within 2–4 weeks. More complex procedures, such as ACL reconstruction or total knee replacement, may require 8–12 weeks or longer for full recovery. Rehabilitation is a critical part of the process, helping you rebuild strength, improve mobility, and return to normal function safely. Dr. Lehman will provide a customized rehabilitation plan and timeline tailored to your specific surgery and goals.

In some cases, yes. Dr. Lehman may recommend PRP injections for knee injuries or physical therapy for patients who are not ready for surgery.
