Surgical treatment outcome of painful traumatic neuroma of the infrapatellar branch of the saphenous nerve during total knee arthroplasty

Figure 1 Postoperative neuroma in a 76 years-old patient after total knee arthroplasty (Case 4). Medial side knee incision following the course of infrapatellar branch of the saphenous nerve.

Figure 2 Surgical exploration revealed neuroma of the infrapatellar branch of the saphenous nerve. ISPN: Infrapatellar branch of the saphenous nerve.

Figure 3 Development of painful saphenous neuroma in a 79 years-old patient after primary total knee arthroplasty (Case 12). The damaged and degenerated nerve was surrounded by scar tissue.

Figure 4 The fibrous nodule containing the neuroma was removed and the nerve was sharply transected approximately 1-2 cm proximal to the neuroma. Its proximal stump was buried to adjacent sift tissues to prevent recurrence.
