There has been a recent resurgence in interest in combined partial knee arthroplasty (PKA) as an alternative to total knee arthroplasty (TKA). The varied terminology used to describe these procedures leads to confusion and ambiguity in communication between surgeons, allied health professionals, and patients. A standardized classification system is required for patient safety, accurate clinical record-keeping, clear communication, correct coding for appropriate remuneration, and joint registry data collection.
An advanced PubMed search was conducted, using medical subject headings (MeSH) to identify terms and abbreviations used to describe knee arthroplasty procedures. The search related to TKA, unicompartmental (UKA), patellofemoral (PFA), and combined PKA procedures. Surveys were conducted of orthopaedic surgeons, trainees, and biomechanical engineers, who were asked which of the descriptive terms and abbreviations identified from the literature search they found most intuitive and appropriate to describe each procedure. The results were used to determine a popular consensus.
Survey participants preferred "bi-unicondylar arthroplasty" (Bi-UKA) to describe ipsilateral medial and lateral unicompartmental arthroplasty; "medial bi-compartmental arthroplasty" (BCA-M) to describe ipsilateral medial unicompartmental arthroplasty with patellofemoral arthroplasty; "lateral bi-compartmental arthroplasty" (BCA-L) to describe ipsilateral lateral unicompartmental arthroplasty with patellofemoral arthroplasty; and tri-compartmental arthroplasty (TCA) to describe ipsilateral patellofemoral and medial and lateral unicompartmental arthroplasties. "Combined partial knee arthroplasty" (CPKA) was the favoured umbrella term.
We recommend bi-unicondylar arthroplasty (Bi-UKA), medial bicompartmental arthroplasty (BCA-M), lateral bicompartmental arthroplasty (BCA-L), and tricompartmental arthroplasty (TCA) as the preferred terms to classify CPKA procedures. Cite this article: 2019;101-B:922-928.
全膝关节置换术（TKA）的替代方法——复合膝关节部分置换术（CPKA）近来重新受到关注。用于描述这些手术的不同术语导致外科医生、相关健康专业人员和患者之间的沟通混淆不清。为了患者安全、准确的临床记录、清晰的沟通、适当报酬的正确编码以及关节登记数据收集，需要一个标准化的分类系统。
使用医学主题词（MeSH）进行高级 PubMed 搜索，以确定用于描述膝关节置换手术的术语和缩写。搜索与 TKA、单髁（UKA）、髌股关节（PFA）和复合 PKA 手术相关。对骨科医生、受训者和生物力学工程师进行了调查，询问他们从文献检索中发现哪些描述性术语和缩写最直观、最适合描述每个手术。结果用于确定一个普遍共识。
调查参与者更喜欢使用“双髁关节成形术”（Bi-UKA）来描述同侧内侧和外侧单髁关节炎；“内侧双间室关节成形术”（BCA-M）来描述同侧内侧单髁关节炎伴髌股关节炎；“外侧双间室关节成形术”（BCA-L）来描述同侧外侧单髁关节炎伴髌股关节炎；以及三间室关节成形术（TCA）来描述同侧髌股关节炎和内侧和外侧单髁关节炎。“复合膝关节部分置换术”（CPKA）是首选的伞式术语。
我们建议使用双髁关节成形术（Bi-UKA）、内侧双间室关节成形术（BCA-M）、外侧双间室关节成形术（BCA-L）和三间室关节成形术（TCA）作为分类 CPKA 手术的首选术语。
