Your Guide to ACL Reconstruction Surgery in Singapore

TL;DR (for long-form articles):

ACL reconstruction restores knee stability after ligament tears, using grafts like hamstring, patellar, quadriceps, or donor tissue.

• Recovery includes physiotherapy over six to twelve months to regain strength, stability, and coordination.
• Consult an orthopaedic specialist in Singapore to choose the right graft and safely return to activities such as HYROX, Pilates, or pickleball.

The anterior cruciate ligament (ACL) is one of the key stabilisers of your knee, connecting your thigh bone (femur) to your shin bone (tibia) and preventing it from moving too far forward or twisting unnaturally. It’s what keeps your knees from giving way during bursts of movement during your HYROX, pilates or pickleball sessions.

When the ACL is injured, though, you may feel more unstable during sports and even walking, as your joints give way and become prone to further injury.

ACL reconstruction surgery allows you to get back to your favourite activities while reducing the risk of long-term problems like meniscus tears or arthritis. Read on to know more about the surgery options and ACL reconstruction graft types available in Singapore.

What Is ACL Reconstruction Surgery and When Do You Need It?

ACL reconstruction is a surgical procedure that replaces a torn ACL with a graft — tissue taken from your own body or a donor — to recreate a strong and functional ligament. The graft acts as a scaffold for new tissue to grow, gradually restoring strength and stability to your knee. These are some of the factors your doctor will consider:

• Severity of the Injury:
  • A complete ACL tear often leads to significant knee instability, making reconstruction necessary.
  • Partial tears may sometimes be managed with conservative treatment, but if instability persists, surgery may be required.
• Symptoms of Instability:
  • Patients experiencing recurrent episodes of the knee “giving way” during sports or daily activities may need surgery to regain stability.
  • Persistent pain and swelling can also indicate the need for surgical intervention.
• Activity Level:
  • Athletes or individuals engaged in high-demand sports may require reconstruction to return to their previous level of activity.
  • Those with a more sedentary lifestyle may manage with physical therapy and rehabilitation.
• Combined Injuries:
  • If there are additional injuries to other ligaments (e.g., MCL, PCL) or the meniscus, surgery may be necessary to address the overall knee stability.
• Response to Conservative Treatment:
  • If physiotherapy and rehabilitation do not improve knee stability or function, ACL reconstruction may be the next step.
  • A lack of improvement in symptoms after a period of conservative management can indicate the need for surgery.

Types of ACL Reconstruction Grafts and Surgery in Singapore

Orthopaedic specialists in Singapore offer several ACL reconstruction options, each with its own considerations: 

Hamstring Tendon Graft

A portion of the hamstring tendon is harvested from the same leg. This graft is strong and flexible, making it a common choice for athletes who need agility, endurance, and a quicker recovery from front-of-knee discomfort. Some patients may notice temporary hamstring weakness, but this usually improves with physiotherapy.

Patellar Tendon Graft

This technique uses the middle third of the patellar tendon with small bone plugs from the kneecap and shin. It provides excellent stability and fixation, which is why it is often recommended for athletes in pivot-heavy or high-impact sports. Some patients, however, experience front-of-knee pain or difficulty kneeling during recovery.

Quadriceps Tendon Graft

Taken from the tendon above the kneecap, sometimes with a bone plug, this graft provides a thick and durable tissue option. It is useful for revision surgeries or patients who prefer not to use hamstring or patellar tendons. Recovery is similar to other autografts, though the incision is slightly larger.

Allograft (Donor Tissue)

Allografts use donor tissue, avoiding the need for tendon harvest from the patient’s own leg. This shortens surgery time and prevents donor-site pain. While modern testing makes transmission risks extremely low, younger athletes may face a slightly higher chance of graft failure.

Recovery and Rehabilitation after ACL Reconstruction

Recovery after ACL reconstruction is gradual. Patients usually take six to 12 months before returning to full activity. It is essential to also follow your rehabilitation plan, doing physiotherapy exercises to restore your knee’s strength and stability. Here’s a typical recovery and rehabilitation timeline after ACL reconstruction: 

Zero to two weeks (Early recovery):

• Control swelling and manage pain
  
• Gentle range-of-motion exercises
  
• Walk with support as advised
  

Two to six weeks (Initial strengthening):

• Gradually increase weight-bearing
  
• Begin physiotherapy for mobility and basic strength
  
• Light balance and coordination exercises
  

Six to twelve weeks (strength and stability):

• Target quadriceps, hamstrings, and hip muscles
  
• Proprioception and stability drills
  
• Gradual increase in functional movements
  

Three to six months (Final rehab):

• Sports-specific exercises and agility drills
  
• Controlled pivoting and directional changes
  
• Prepare for gradual return to activity
  

Six to twelve months (Full recovery):

• Full return to competitive sports or high-demand activities
  
• Continue strength and conditioning program
  
• Monitor and correct any movement or muscle imbalances
