The hip joint is a ball and socket joint where the femoral head (top of the thigh bone) sits within a corresponding socket (the acetabulum) that is part of the pelvis.

As well as conditions that affect the actual ball and socket part of the hip joint, there are a number of other structures around the hip joint that can be injured. These can cause pain, difficulty with walking or discomfort/limitations in performing athletic activities or everyday tasks such as squatting.

Many of these conditions cause a similar pattern of pain symptoms. People often describe pain in the buttock, the groin or over the outer aspect (the “point”) of the hip. Differentiating these varied conditions is key to providing appropriate advice and treatment.

Dr McDarra treats a variety of hip and hip-related conditions including arthritis of the hip as well as hip fractures, muscular tears around the hip, bursitis conditions and sports related hip injuries.


The knee joint is a complex structure involving the articulating surfaces of the three bones that meet at the knee (the femur, the tibia and the patella) as well as multiple ligaments, tendons and soft tissue structures that provide stability, support and motion to the joint.

Injury to the ligaments, tendons or bones at the joint can occur either chronically or acutely – arthritis, meniscus tears and ACL rupture being prime examples. As well as being painful, these injuries or conditions can cause stiffness, deformity or instability of the joint. If left untreated, many acute conditions can progress and eventually lead to full-fledged arthritis.

Many painful or disabling conditions of the knee are amenable to surgical correction and can provide excellent return of function and greatly increase quality of life.

Foot & Ankle

The ankle, or the talocrural region, is the region where the foot and the leg meet. The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint.

Injuries to the ankle are among the most common lower extremity sporting injuries. The ankle joint is a complex joint formed by three bones. It consists of the tibia provides the major weight bearing surface where it joins the talus.

The ankle is one of the most commonly injured joints of the body and is frequently observed with activities that involve jumping or running. An examination of the ankle should also include a thorough evaluation of the foot. This includes an assessment of gait pattern, standing posture, and shoe wear pattern. Any obvious gross deformity, malalignment, or atrophy should also be observed and noted. Acute injuries to the ankle commonly result in swelling and the development of ecchymosis. Accumulation of swelling typically occurs around the lateral and/or medial malleoli, and may move distally into the foot.
