A series of patients whose patella has been resurfaced by a prosthesis has been compared with a similar group whose patella has been resected. Patellectomy has been an acceptable procedure in the treatment of severe injuries and degenerative changes of the patella, but the indications for this operation are not well defined in all fields. Satisfactory results following Vitallium patellaplasty have been better than those following patellectomy in osteoarthrosis. Extension is more complete; flexion has been satisfactory; cosmetic appearance is more desirable. Prosthetic resurfacing with a Vitallium prosthesis has been a satisfactory procedure in individuals who develop symptoms from a painful patellofemoral joint when the remainder of the joint has not deteriorated sufficiently to indicate need for total knee replacement. Patellaplasty has provided years of pain-free patellofemoral function and prevented the alteration of normal joint mechanics that occurs with patellectomy.
对一系列接受髌骨假体表面置换的患者与另一组接受髌骨切除术的类似患者进行了比较。髌骨切除术一直是治疗髌骨严重损伤和退行性变的一种可接受的手术方法，但在所有领域中该手术的指征并不明确。在骨关节炎中，维氏合金髌骨成形术后的满意结果优于髌骨切除术后的结果。伸展更完全；屈曲情况令人满意；外观更理想。对于那些髌股关节疼痛但关节其他部分尚未严重恶化到需要进行全膝关节置换的患者，使用维氏合金假体进行假体表面置换是一种令人满意的手术方法。髌骨成形术提供了多年无痛的髌股关节功能，并防止了髌骨切除术后出现的正常关节力学改变。
