Dr Kumar is an orthopaedic surgeon specialising in disorders of the knee and shoulder. He was born and raised in Newcastle, NSW, completing undergraduate studies in Science/Law in his hometown before graduating from the University of Sydney Medical Program with Honours. He then completed his general orthopaedic training through the Australian Orthopaedic Association. During his final year, he served as the President of the Australian Orthopaedic Registrars Association (AORA).

After obtaining his fellowship, Jai travelled to Europe for a further year and a half of subspeciality training focusing on knee and shoulder surgery with a special interest in sports arthroscopy. During this time he worked with Dr Ray Moran and Dr Hannan Mullett at the Sports Surgery Clinic in Dublin, Ireland, followed by time with Professor Philippe Hardy at Hôpital Ambroise-Paré in Paris, France. In addition to this, he travelled to England, Scotland, Austria and Belgium to further solidify his knowledge.

The aim for Jai was to return from Europe with a skill set that offers his patients not only the most advanced techniques but also surgery that draws on a wide breadth of experience.

Jai's focus is in the lower limb is on knee surgery including knee arthroscopy, ACL and multiligament knee reconstruction, patellar (kneecap) stabilisation, cartilage and meniscal repair and optimisation, as well as knee replacement.

In the upper limb, Jai deals with all aspects of shoulder and elbow surgery including bursitis and impingement, rotator cuff repair, biceps tendon injuries, shoulder stabilisation surgery (for dislocations), acromioclavicular (AC) joint injuries as well as shoulder replacement.

Jai feels that a multidisciplinary approach to total patient care is imperative to obtain optimum outcomes. The role of physiotherapists, sports physicians, coaches, rehabilitation providers and other allied health personnel make up an integral part of his practice and maintaining strong and free-flowing lines of communication is the key to this.
