โฌ๏ธ For years, the management of degenerative meniscal tears has been a source of debate within the orthopaedic community.
โฌ๏ธ While evidence generally discourages arthroscopic meniscal surgery for degenerative tears, clinical guidelines have remained ambiguous regarding patients who present with mechanical symptomsโsuch as locking, catching, clicking, or popping of the knee.
โฌ๏ธ A new systematic review and meta-analysis published in the Journal of Orthopaedic Reports 2025 by Zilani et al. challenges the notion that mechanical symptoms justify surgical intervention, offering pivotal insights into the long-term outcomes of surgery versus non-operative management.

๐ Degenerative meniscal tears are common in older populations and are often associated with knee osteoarthritis.
๐ Current guidelines, such as those from the AAOS American Academy of Orthopaedic Surgeons, often provide unclear recommendations for tears accompanied by mechanical symptoms, leading many surgeons to view these symptoms as a valid indication for surgery.
๐ However, the efficacy of this approach has been questioned.
๐ This new review aimed to fill a critical gap in the literature by specifically analyzing 5-year outcomes in patients with degenerative tears and mechanical symptoms, comparing those who received surgery against those managed non-operatively such as physical therapy.

โฌ๏ธ The review analyzed six randomized controlled trials involving 1157 participants.
โฌ๏ธ The results highlight a distinct trade-off between subjective health perception and objective joint preservation.

โฌ๏ธ Contrary to the belief that surgery resolves mechanical dysfunction, the study found no significant difference between arthroscopic surgery and non-operative management regarding knee function, activity levels, or meniscal evaluation at the 5-year mark.
โฌ Scores for the Lysholm Knee Scoring Scale measuring limp, locking, and instability showed no statistically significant difference between the groups p = 0.07.
โฌ๏ธ Activity levels, measured by the Tegner Activity Scale, were identical between surgical and non-surgical patients p = 1.00.
โฌ๏ธ Pain scores VAS for activity and rest also showed no significant statistical difference.

โฌ๏ธ Perhaps the most critical finding of this review is the long-term impact of surgery on joint health.
โฌ๏ธ Patients who underwent arthroscopic surgery demonstrated a significantly higher rate of osteoarthritis progression compared to those treated non-operatively.
โฌ๏ธ The odds ratio for radiographic osteoarthritis progression was 2.09 in the surgical group.
โฌ๏ธ This suggests that while removing torn tissue might intuitively seem helpful, the surgical intervention itselfโor the resulting loss of meniscal tissueโmay accelerate the degenerative process within the knee joint.

โฌ๏ธ Interestingly, while specific knee function scores did not differ, patients in the surgical group reported significantly better general health scores on the EQ-VAS European Quality of Life Visual Analog Scale compared to the non-operative group p < 0.00001.
โฌ๏ธ This suggests that surgery may offer a psychological benefit or a perceived improvement in overall well-being that is not captured by specific knee function metrics.

โฌ๏ธThis study provides high-quality evidence suggesting that mechanical symptoms should not automatically trigger a decision to operate.
๐ค For Patients
โฌ๏ธ If you have a degenerative tear with clicking or catching, physical therapy is likely to yield similar functional results to surgery over five years, without the increased risk of accelerating osteoarthritis.
๐จโโ๏ธ For Clinicians
โฌ๏ธ The presence of mechanical symptoms does not necessarily predict a better response to surgery.
โฌ๏ธ The "quick fix" of removing the mechanical obstruction must be weighed heavily against the doubled risk of long-term osteoarthritic changes.
๐ ๐พ๐ค๐ฃ๐๐ก๐ช๐จ๐๐ค๐ฃ
๐ The findings of Zilani et al. suggest that non-operative management should be the primary treatment pathway for degenerative meniscal tears, even when mechanical symptoms are present.
๐ While surgery may improve a patient's general perception of health, it fails to provide superior knee function and actively contributes to the worsening of osteoarthritis over time.
