Locking symptoms in the knee joint generally occur due to meniscal tears and loose bodies. The purpose of this report is to describe a case of nodular synovitis, an intra-articular tenosynovial giant-cell tumor, as a rare differential diagnosis for locking of the knees. Arthroscopic removal ensured prompt symptomatic relief without any recurrence at 1-year follow-up. Nodular synovitis has a better prognosis with limited risk of local recurrence. There is no role for complete synovectomy or postoperative radiotherapy. Knee arthroscopy is the procedure of choice, and prompt symptomatic relief is the usual outcome expected; however, a close follow-up is still warranted to look for recurrence.
