Medial Cruciate Ligament (MCL) Repair/Reconstruction

Your post-operative recovery will be based on what other injuries are being treated (meniscus, ACL, PCL, etc) in addition to the MCL repair/reconstruction.  The typical rehabilitation for an isolated MCL repair/reconstruction is as follows:

• Hospital Stay: You will typically only require an overnight stay in hospital.  There are situations where discharge home the same day of surgery can occur. 

• Weight bearing: You will be weight bearing as tolerated right after with the use of crutches.

• Brace: You typically placed in an unlocked hinged knee brace, for 6 weeks.  

• Range of motion: Early motion starts right away.    

• Ice and elevation: Used frequently to control pain and swelling.  Youn should ice for 20 minutes 3-4 times a day right after surgery.  An ice/compression machine can be hired from a 3rd party. 

• Physiotherapy: Starts a few days after surgery, focusing on gentle range-of-motion and quadriceps/hamstring activation. 

• It is normal for the top dressing to become moist with arthroscopic fluid in the first 1–2 days.

• After 1-2 days, remove the outer dressing and leave the smaller waterproof dressings in place.

• Dressings may be removed completely after 7 days.

• Incisions typically heal within two weeks.

• Showers are permitted while the wounds are covered with waterproof dressings during the first 2 weeks.

• Do not submerge incisions in water (baths, pools, ocean) for 4 weeks.

• A wound check with your GP at the two-week mark is recommended.

• Absorbable sutures are typically used and do not require removal, though occasionally small remnants may naturally surface during healing.

Blood clots (deep vein thrombosis or pulmonary embolism) are uncommon but can occur after surgery.
You can reduce the risk by:

• Moving your foot and ankle regularly while resting.

• Walking early with assistance.

• You will likely be instructed to take aspirin for 2-4 weeks to prevent DVT/PE.

• Avoiding long periods of sitting or immobility.

Seek immediate medical attention if you develop calf pain, swelling, chest pain, or shortness of breath.

• Use ice regularly (20 minutes at a time, several times per day).  You may hire an ice machine from a 3rd party.

• Take prescribed pain relief medications as directed.  Opioid medication can be used, but there are known side effects such as nausea, vomiting, constipation, and dependence; thus, non-opioid medications should be prioritized when medically tolerated. 

• Use a compressive dressing on the knee for 6-12 weeks to help with swelling

• Begin gentle range-of-motion and muscle activation exercises as soon as recommended.

• Use walking aids to help with gait

You should contact your surgeon or clinic immediately if you notice:

• Increasing redness, swelling, or foul-smelling drainage from the wound.

• Persistent or worsening pain not controlled by medication.

• Fever, chills, or night sweats.

• Calf pain or swelling (possible blood clot).

• Acute injury to your operative extremity.

Prompt review allows early management of potential complications.

Recovery depends on injury severity and whether other ligaments were repaired. Return to activities depends on the nature and intensity of the recreation.

This is a general guideline:

• Running: once knee swelling, pain has resolved, and adequate strength has been retained- typically 3-4 months

• Non-cutting activities/sport (golf, cricket, surfing, etc), typically 5-6 months

• Training for sport, typically 6-9 months

• Cutting sports (football, rugby, basketball, netball, etc), typically 6-12 months

There are no strict guidelines on when to return to sport after MCL repair/reconstruction, but it typically takes 6-12 months.

• You can usually drive when you can safely control the vehicle and perform an emergency stop comfortably.

• This is typically around 4–6 weeks after surgery for right knee surgery, and 2-3 weeks for the left knee.

You must not drive while taking strong pain medication (e.g., opioids).

Return to work depends on your occupation:

• Office or sedentary work: 1–2 weeks (once you can safely commute).

• Light manual work: 4–6 weeks.

• Heavy manual labour: 3–4 months or longer, depending on recovery.

Yes. Physiotherapy is essential for optimal recovery and long-term success after MCL repair/reconstruction. 

Your physiotherapist will:

• Guide you through a structured rehabilitation program.

• Focus on restoring range of motion, strength, balance, and neuromuscular control.

• Progress exercises gradually from early mobility to return-to-sport conditioning.

Most patients continue physiotherapy for 6–9 months to achieve full recovery, including returning to sport.

Although MCL surgery is safe, complications can include:

• Infection

• Blood clots (DVT/PE)

• Knee stiffness or limited range of motion

• Persistent medial laxity or instability

• Graft stretching or failure

• Hardware irritation (may require removal)

• Donor site soreness (if autograft used)

• Numbness around the incision area

• Residual pain or swelling

• Fracture

• Pain and weakness from graft harvest
