Twenty six underwent post-operative radiotherapy. All patients were followed up, and the average follow-up period was 54 months (range: 24 to 72 months).Results: All 26 patients who received external radiotherapy showed no recurrence at post-operative follow-up; The Lysholm knee joint function score increased from 54.3\u00b19.0 at pre-operation to 71.2\u00b16.7 at post-operation (paired t-test, t = \u221213.35, P&lt;0.01).Conclusions: Arthroscopic synovectomy is an ideal treatment for PVNS of the knee. Adjuvant post-operative external radiotherapy prevents the recurrence of diffuse PVNS.doi: http:\/\/dx.doi.org\/10.12669\/pjms.314.7383How to cite this:Li W, Sun X, Lin J, Ji W, Ruan D.
