"In our opinion, arthroscopic and limited open techniques (4,20,28) provide inadequate exposure of the knee joint, particularly postero-laterally and in the region of the popliteus tendon. Furthermore, most reports of treatment of DPVNS have small numbers of patients, often collected over a number of years with more than one joint included. (1,2,8,8,12,16,18,22) To the best of our knowledge, no reports in the literature contain large numbers of patients with DPVNS of the knee, with adequate preoperative staging, and long-term clinical or MRI evaluation. (15,17,21)"
The article concludes: "The results of our study suggest that complete synovectomy is the procedure of choice to decrease the risk of recurrence of DPVNS of the knee. Arthroscopic or limited open techniques or radiotherapy may reduce the amount of DPVNS tissue and associated symptoms in the short term, but will not eradicate the disease. In contrast, an extensile open surgical approach allows excellent visualization for removal of intra-and extra-articular DPVNS tissue with an acceptably low complication rate. We continue to use arthroscopy for pre- or post-operative diagnostic biopsies or treatment of early primary or residual disease following open synovectomy. Our current practice is to assess patients with MRI pre-operatively, three months post-operatively, and annually thereafter."

Note: I can't locate a date on this article, but the most recent citation at the end of the article is dated 1999, so this Harvard article is more recent than 1999.
