“…In our study, it was interesting that the FF cases with fibrous band were accompanied by the thicker fabella. This finding supports the previous observations of Seebacher et al [12] and Minowa et al [8] As a landmark ILG…”

“…Regarding the PT's early developmental fibular insertion, [1] the fibrous tissues attached directly to the inferior aspect of PT and were subsequently defined as PF. Similarly, Minova et al [8] claimed the relation of AL and PF with PT as follows: "AL forms a retinaculum for PT but PF is the branch of PT". Although their statements contain both ALs and ALd, each of these parts was not specified by Minova et al [8] Similar to this study, Ishigooka et al [10] identified PF in all cases.…”

Injuries of posterolateral knee structures are uncommon, however they are functionally important as these structures play a major role in dynamic and static stabilization of the knee against varus and external rotation stresses. [1][2][3][4][5][6] The posterolateral corner of the knee (PLC) has been defined as the "dark side" by orthopedists because of its complex structure. [1,4,7,8] In addition, there are discrepancies between descriptions of the various ligamentous structures such as the fabellofibular (FF), arcuate popliteal (AL) and popliteofibular (PF) ligaments in the literature. [9][10][11][12][13][14][15] One of the discrepancies is variety of descriptions of AL and FL. In some publications FF has been defined as "the strong vertical part of AL", while in others it has

Influence of a fabella in the gastrocnemius muscle on the common fibular nerve in Japanese subjects

et al. 2012

View full text Add to dashboard Cite

The fabella is a sesamoid bone located in the proximal tendon of the gastrocnemius muscle. In rare cases, its presence may lead to a variety of clinical problems, including fabella syndrome and common fibular (CF) nerve palsy. The purpose of this study was to analyze the morphology of the fabella and CF nerve and discuss the influence of any existing fabellae on the size of the CF nerve. The morphology of the fabella and CF nerve in the popliteal region of the lateral head of the gastrocnemius muscle was investigated in 102 knees of 51 Japanese cadavers. The maximum circumference of the thigh, knee, and calf and the frequency, position, and size of the fabella were measured. In addition, the CF nerve width and thickness were measured proximal to the fabellar region and again as the CF nerve passed posterior, lateral, or medial to the region. A fabella was observed in 70 knees (68.6%). The CF nerve adjacent to the fabella was significantly wider and thinner than in the region proximal to the fabella (P < 0.001). In cases in which a bony fabella was present, there was a significant relationship between the thickness of the CF nerve and the circumference of the thigh and knee. The following factors were observed to contribute to the presence of a fabella causing alterations in the size of the CF nerve: a bony fabella, a CF nerve path posterior or lateral to the fabella, and subjects with a thin physique and bony fabella.

The gastrocnemiofibular ligament: A new, more anatomically accurate name for the fabellofibular ligament—An original magnetic resonance imaging study and meta‐analysis

Introduction The fabellofibular ligament (FFL) is a component of the posterolateral corner (PLC) of the knee and is an anatomically variable static stabilizer. Several investigations have reported prevalence rates for the FFL among their subjects, but no overall prevalence rate has been reported. Materials and Methods We conducted a meta‐analysis of all relevant studies reporting prevalence rates of the FFL according to PRISMA and AQUA guidelines and pooled prevalence data using MetaXL 5.3. We also conducted a retroactive magnetic resonance imaging (MRI) study of 100 knees to assess FFL and fabella prevalence. Results Twenty‐one studies (from 18 articles) and our MRI data were used in this meta‐analysis (n = 1,176 knees). The pooled prevalence estimate (PPE) for FFL absence was 37.4% (95% confidence interval [CI], 24.5–51.3%). When divided by continent, PPEs of FFL absence were 31.5% (95% CI, 1.4–72.7%), 58.2% (95% CI, 44.1–71.6%), and 29.0% (95% CI, 14.7–45.7%) for North American, European, and Asian subjects, respectively. Cadaveric and MRI studies showed PPEs of FFL absence of 31.5% and 49.7%, respectively. Our MRI results showed PPEs of FFL and fabella absences of 42.0 and 80.0%, respectively. Conclusions Understanding prevalence rates and anatomical geometry of the FFL will assist surgeons in repairing PLC injuries. Our MRI data and previous studies suggest the FFL is frequently present in knees lacking a fabella. Based on the observations of this study, we propose the ligament be renamed the gastrocnemiofibular ligament.
