Knee Treatment

Knee replacement, repair & reconstruction.

Dr. Maclean’s common surgical procedures include robotic assisted and bilateral knee replacements as well as knee ligament and meniscal repairs following sever and ongoing knee injuries.

Robotic Assisted Knee Replacement Surgery is when a surgical plan is developed, combining the patient’s X-Ray derived 3D bone model with intraoperative assessment of natural knee motion.

Robot assistance then ensures precision and accuracy when implementing this plan providing individualised, optimal placement of the prosthesis.

When inflammation and pain occurs in one or both knees, it usually indicates that the cartilage in the joints has worn away. Knee replacement surgery may be done to replace the damaged joints and to relieve symptoms. Surgery may involve any combination of total knee replacement or partial knee replacement.

Simultaneous bilateral knee replacement is when both knees are repaired at the same time, staged bilateral knee replacement refers to one knee at a time.

An ACL injury is a tear or sprain of the anterior cruciate ligament (ACL) — one of the major ligaments in your knee. ACL sprains or tears can be very painful and require surgery to replace the torn ligament followed by rehabilitation to help you regain strength and stability.

The meniscus is a piece of cartilage in your knee that cushions and stabilizes the joint. Symptoms include pain, joint effusion, instability and possible joint locking. Treatment for meniscal tears depends on the size and location as well as age, activity level and related injuries.

Robotic Knee Replacement Surgery

Combining Experience with the Latest Technology in Joint Replacement Surgery

With over 20 years’ experience in joint replacement surgery, Dr Maclean is able to provide the Sunshine Coast and Noosa Community with Robotic Assisted Knee Replacement Surgery.

A surgical plan is developed, combining the patient’s X-Ray derived 3D bone model with intraoperative assessment of natural knee motion. Robot assistance then ensures precision and accuracy when implementing this plan providing individualised, optimal placement of the prosthesis.

During the surgery further information is collected providing feedback on soft tissue balance and knee motion. Use of the robot can then assist in dynamically fine tuning the procedure, if required.

Dr Maclean is delighted to be able to offer this service, having been central to pioneering the introduction of this technology to the Sunshine Coast for the past few years.

Anterior Cruciate Ligament (ACL) Reconstruction


  • Decreased graft donor site morbidity (less pain and inflammation in relation to obtaining the graft).
  • Improved speed of return of hamstring strength.
  • Larger graft size that reduces the chance of reinjury.
  • Less traumatic surgical technique leading to less bony bruising and therefore less pain.
  • Stronger fixation allows for accelerated rehabilitation allowing for an earlier return to work and sports training.

The ACL is an important ligament for knee stability which is commonly injured, particularly in sports which involve sudden acceleration/ deceleration and pivot.

Not all ACL injuries require surgery – it depends on age, desire to return to ‘at risk’ sports, functional demands, or if symptomatic instability is present. It is also important to repair or reconstruct an ACL injury to improve outcome when addressing other injuries, such as a meniscal tear requiring repair, or if the ACL injury is a component of a multiligament injury of the knee.

When surgery is required, Dr Maclean utilises an advanced technique where only one hamstring tendon is typically required to reconstruct this ligament.

This ACL system regularly results in a stronger, larger diameter graft, to reconstruct the ligament.

This larger graft diameter has been shown to reduce the incidence of re-injuring the knee in the future; and superior graft fixation allows for early walking, no need for a knee brace, and an accelerated rehabilitation.

Meniscal Tears

Meniscal tears can occur due to trauma as well as a result of degenerative changes. The main function of the meniscus is to spread force evenly within the knee joint. With a meniscal tear this function can be compromised, causing the knee to become arthritic over time. The tear itself can also cause pain, giving way, swelling, and locking or catching symptoms.

For younger people, the meniscal tear results from a traumatic injury and is suitable for repair. Successful repair restores function, delaying or preventing the development of osteoarthritis (degeneration of the knee joint surfaces).

Time to surgery for this repair is critical with early repair resulting in a higher chance of success and better outcomes.

For degenerative tears the meniscus is often not repairable. It depends on the severity and frequency of symptoms whether or not surgery would be appropriate.

If appropriate it involves a keyhole operation which is performed as a day surgery procedure, with rapid recovery.

Patella Dislocation/Mal-tracking

There are 3 broad categories when dealing with patellofemoral disorders (the joint between the kneecap and the remainder of the knee);

  1. First occasion traumatic, acute patella dislocation

Typically involves a traumatic injury in an otherwise normal knee.

If no bone or cartilage injury or any injury to other structures in the knee, can often be treated non-operatively.

If pre-existing anatomical predisposition to recurrent dislocation may require surgery.

Initial appropriate management is necessary to optimise outcome and decrease the likelihood of ongoing knee concerns.

  1. Recurrent instability/ mal-tracking

Often there is an underlying mechanical, or anatomical reason, for instability. The reason for the instability is often multifactorial. In this situation clinical examination and medical imaging is required to evaluate and develop an individualised plan to address the stability of this joint. Surgery may be required, depending on the degree of instability and symptoms present. An appropriate physiotherapy program is also typically beneficial.

  1. Patellofemoral Arthritis

Often results from chronic patella mal-tracking disorders. Once advanced arthritis is present the most reliable and effective surgery is typically a joint replacement.
