Abstract

Objective: To highlight the incidence of grade III PCL injuries with simultaneous PCL & popliteus injury.

Methods: Inclusion criteria: patients who underwent PCL reconstruction for grade III PCL tear & minimum of 1-year follow-up. Exclusion criteria: associated ACL injury & insufficient follow up. Patients seen postoperatively at 2 weeks, 6-8 weeks, 4-6 months, 6-9 months, 1 year, and 1 + years.

Results: 89.5% of patients in this study had an associated popliteus injury.

Conclusions: Isolated grade III PCL injury may not frequently exist, rather undiagnosed & untreated concurrent popliteus injury can have less successful outcomes after isolated PCL reconstruction.

Keywords: Popliteus; Posterior cruciate ligament (PCL); Posterolateral corner (PLC).

Fluid extending along the popliteus bursa. Sagittal T2-weighted images show fluid in the popliteus bursa (arrow), which may be mistaken for a popliteus muscle or tendon tear. Note the presence of joint effusion and lack of edema in the popliteus muscle.

Fig. 2
Pseudotear of the lateral meniscus. Sagittal PD-weighted images show a linear hyperintense interface (arrow) between the popliteus and the posterior horn of the lateral meniscus. This may be mistaken for a lateral meniscal tear.
