Transient posterior knee pain with the meniscal arrow
1Department of Orthopaedic Surgery, The University of Virginia, Charlottesville 22908, USA.
Summary
Transient posterior knee pain occurred in 31% of patients after all-inside meniscal repair with the absorbable Meniscal Arrow system. This pain resolved within six months for all patients, aiding surgeon counseling.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomaterials Science
Background:
- All-inside meniscal repair techniques aim to improve meniscal healing and patient outcomes.
- The absorbable Meniscal Arrow system is utilized for all-inside meniscal repair.
- Posterior knee pain is a potential post-operative complication following knee surgery.
Observation:
- A 31% incidence of focal posterior knee pain was observed in the initial patient cohort undergoing meniscal repair.
- The reported posterior knee pain was transient in nature.
- Pain resolution occurred in all affected patients within a 6-month follow-up period.
Findings:
- Posterior knee pain following meniscal repair with the Meniscal Arrow system is a common, albeit temporary, issue.
- The duration of the implant did not correlate with the occurrence or severity of posterior knee pain.
- Patient counseling regarding this transient post-operative symptom is warranted.
Implications:
- Surgeons should be aware of the high incidence of transient posterior knee pain after Meniscal Arrow repair.
- Informed consent and patient education should include discussion of this potential post-operative symptom.
- Further research may explore the etiology of this transient pain to potentially mitigate its occurrence.
