Shoulder Arthroscopy
Arthroscopy has been one of the major advancements in Orthopaedic Surgery and advanced the knowledge and skills of shoulder surgery over the past decade.
Now the vast majority of elective shoulder surgery can be performed arthroscopically, with significant advantages to the patient and surgeon.
However the skills and equipment are completely different to traditional open surgery.
In this section I have tried to include information that has been difficult to find in the standard literature and some tools and aides to assist with the understanding, training and skills development for arthroscopic surgery. -
Acute Shoulder Dislocations
The reported rate of redislocation is 17% to 96% with a mean of 67%
Increased rate of recurrence in younger age groups

Total Knee Replacement
You will most likely be admitted to the hospital on the day of your surgery. After admission, you will be evaluated by your anesthetist. The most common types of anesthesia are general anesthesia, in which you are asleep throughout the procedure, and spinal or epidural anesthesia, in which you are awake but your legs are anesthetized.

Shoulder Rotator Cuff Tendon Repair
Within the active population, no matter the patients age, an active sporting individual with a traumatic rotator cuff tear is an indication for arthroscopic rotator cuff repair. The reason for this is both pain and the functional demand of the patient. A sporting individual would require optimum strength of all their shoulder muscles for sports and overhead activities. Thus, a fully functional cuff is a necessity. Secondly, it has been proven that rotator cuff tears increase in size over time. Partial thickness tears progress to full thickness tears, and small full thickness tears progress to large to massive full thickness tears.

Arthroscopic Knee Surgery
The word arthroscopy is devised from two words: arthro – meaning joint, and scopy – meaning the visualisation of. Therefore arthroscopy is an operative technique to allow the visualisation and ideally treatment of structures within the knee joint.

Posterior Cruciate Ligament
The Posterior Cruciate Ligament (PLC) originates from the posterior part of the lateral surface of the medial femoral condyle in the intercondylar notch. The PCL has an average length of 38mm and an average width of 13mm. It is narrowest in its mid portion and fans out to a greater extent superiorly and inferiorly. The fibres are attached to the tibial insertion which occurs in a depression posterior to the intra-articular upper surface of the tibia. This is therefore outside the knee joint per se. The attachment extends for up to 1cm distally onto the adjoining posterior surface of the tibia. Immediately proximal to the tibial attachment the PCL has slips that blend with the posterior horn of the lateral meniscus. These slips variably pass anterior to the PCL (ligament of Humphrey) and/or posterior to the PCL (ligament of Riesburg).

Frozen Shoulder
Frozen shoulder is an extremely disabling condition, presenting with and remitting shoulder pain and stiffness. This was well defined by Codman in 1934, who described the first and best classical diagnostic criteria still used to this day.

Anterior Cruciate Ligament
Anterior cruciate ligament reconstruction (ACL reconstruction) is carried out after an injury to the anterior cruciate ligament. The ACL is essential for normal knee function and stability: it attaches from the bottom of the thigh bone (lateral femoral condyle of the femur) to the top of the shin bone (medial tibial plateau) and prevents excessive forward (anterior) movement of the shin bone, excessive inward (internal) rotation of the shin bone, excessive bending the knee sideways toward the body, and knee hyperextension.
