30 Arthroplasty Thesis Topics
Academic session 2026-2027 · 30 topics
This page lists 30 arthroplasty thesis topics for FNB, DrNB and PDCC candidates in India for the 2026-2027 academic session. Arthroplasty research has a built-in measurement structure: pre and post-operative functional scores are part of standard care, radiological implant assessment is done at defined follow-up intervals, and complications are recorded in the operative log.
The arthroplasty thesis topics below are built on those records. They cover total knee and hip arthroplasty outcomes, implant position and alignment, complications including infection and instability, revision surgery, unicompartmental arthroplasty, and patient-reported outcomes.

Choosing a Arthroplasty thesis topic
Which outcome measures are standard in arthroplasty research?
The Oxford Knee Score and Knee Society Score for knee arthroplasty, the Oxford Hip Score and Harris Hip Score for hip arthroplasty, and the Western Ontario and McMaster index for symptom severity. Functional scores before and after surgery at three and twelve months produce the primary results. State the exact instrument and version, since several scoring systems exist and are not interchangeable.
What radiological assessments are done in arthroplasty research?
Component position measured on standardised plain radiographs, implant alignment on long leg films, and lucent lines or osteolysis on sequential films. Correlation between radiological and clinical outcome is a well-regarded design that requires nothing beyond images already taken for clinical purposes.
What sample size is realistic?
A busy arthroplasty unit performing five or more procedures a day supports one to two hundred cases over twelve months for knee or hip replacement studies. Revision arthroplasty and unicompartmental replacement accumulate more slowly and should be planned as series.
Thesis and protocol questions
How is a thesis topic different from a thesis protocol?
The topic is the title — the question a study sets out to answer, together with the population and the design. The protocol is the full document built around it: background, review of literature, aims and objectives, inclusion and exclusion criteria, sample size calculation, methodology, statistical plan, ethics considerations, consent documents and references. A topic is agreed with a guide first; the protocol is written afterwards and submitted to the institutional ethics committee.
When does a postgraduate thesis have to be submitted?
For most Indian postgraduate programmes the protocol is submitted within the first six months of joining, and the completed thesis is submitted at least six months before the final examination. Exact deadlines are set by the university, so the departmental circular for the current session takes precedence over any general timeline.
How is sample size decided for a postgraduate thesis?
Sample size follows from the primary objective, not the other way round. A prevalence study is powered from an expected proportion and an acceptable margin of error; a comparative study is powered from the expected difference between groups, the standard deviation, alpha and desired power. The figure should then be checked against the institution's actual case load for the study period, because a statistically ideal sample that cannot be recruited in the time available is not a workable plan.
Does a thesis topic need ethics committee approval?
Yes. Every postgraduate thesis involving human participants, human data or human samples requires clearance from the institutional ethics committee before data collection begins. Approval is granted on the protocol rather than on the title, and the submission usually includes the protocol, the participant information sheet and the consent form in English and in the local language.
What makes a topic realistic for a three-year postgraduate programme?
A workable topic can be completed at a single centre, with equipment and investigations that are already available in routine practice, within roughly eighteen months of data collection. Topics that depend on external funding, specialised assays, multicentre coordination or long follow-up tend to stall. Choosing a condition the department already sees in volume matters more than choosing a novel one.
Can a thesis be published as a research paper afterwards?
Yes, and it is generally expected. A thesis is usually condensed into a paper of around three to four thousand words, restructured into the standard introduction, methods, results and discussion format, with the review of literature shortened considerably. Journals differ in their requirements, and the ethics approval number from the original thesis is normally cited in the methods section.
