Introduction and importance: Calcific tendinitis occurring in the popliteal tendon is extremely rare and has rarely been reported in the past. This case describes a patient who underwent arthroscopic surgery to remove the calcification of the popliteal tendon and achieved satisfactory results after surgery, providing valuable evidence for the feasibility of arthroscopic treatment of calcific tendinitis of the popliteal tendon.
Case presentation: The patient was a 55-year-old female who was admitted to the hospital due to right knee pain and limited mobility. Physical examination revealed right knee swelling with increased skin temperature and flexion and extension disorders. Imaging, arthroscopy and pathological examinations confirmed "calcific tendinitis of the popliteal tendon". After the operation, the patient's right knee pain disappeared and her movements were normal.
Clinical discussion: Calcific tendinitis of the popliteal tendon is extremely rare. The pathogenesis of this disease is relatively complex. Conservative treatment is usually chosen. If it is ineffective, arthroscopic removal of the lesion is chosen. The patient's symptoms can be relieved immediately after the operation, and after reasonable rehabilitation exercises, the patient can quickly resume daily work and life.
Conclusion: Calcification foci at the popliteal tendon are the main factors causing knee pain and dysfunction. Arthroscopic surgery to completely remove calcification foci at the popliteal tendon can achieve satisfactory clinical results. It has the advantages of less trauma, immediate pain relief, and rapid functional recovery. It is especially suitable for patients after conservative treatment has failed.
