Pain control after arthroplasty has been a key concern for orthopedic surgeons. After total knee arthroplasty (TKA), a small group of patients developed a painful joint with suboptimal range of motion. Manipulation under anesthesia increases flexion and extension while decreasing pain in most cases. ⋯ Group A had an incidence of manipulation of 4.75% (37/778). Of 357 patients, 8 required manipulation in group B, which is an incidence of 2.24%. We recommend that orthopedic surgeons consider using a multimodal pain management protocol for TKA.

Injury of the infrapatellar branch of the saphenous nerve (ISN) may be caused by a surgical laceration or trauma about the knee and can result in formation of a painful neuroma. There has been no report of knee stiffness after a total knee arthroplasty secondary to a painful neuroma of the ISN. ⋯ A neuroma of the ISN was resected, and the pain as well as the stiffness of the knee resolved. A source of pain such as a neuroma should be considered as a cause of reversible knee stiffness or "pseudoarthrofibrosis" after a total knee arthroplasty.
