Minimally Invasive Arthroscopic Approach to Popliteal Tendon Impingement in a Degenerative Knee: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Posterolateral knee pain can occur due to various causes, including meniscal tears, intra-articular loose bodies, ligament injuries, and tendinitis. Popliteal tendon impingement (PTI) due to osteophytes is a less common but significant cause of posterolateral knee pain, and treatment options for PTI are not well established. This report aimed to explore a minimally invasive approach to treating PTI in a degenerative knee using arthroscopic osteophyte resection. A 62-year-old man presented to our hospital with posterolateral knee pain and restricted range of motion (ROM) in the right knee. Imaging revealed significant osteophyte formation causing PTI. Conservative treatment failed. Thus, arthroscopic osteophyte resection was performed. Postoperatively, the patient significantly improved. The ROM improved from 90° of flexion with an extension lag of 5° preoperatively to 130° of flexion and full extension at three months postoperatively. The Knee Injury and Osteoarthritis Outcome Score (KOOS) improved from 52% to 74%, with complete resolution of pain. Comprehensive management, including precise diagnosis, judicious patient selection, and targeted arthroscopic intervention, is critical regardless of whether PTI is encountered in degenerative knees or following total knee arthroplasty (TKA). Arthroscopic osteophyte resection is a promising option for alleviating pain and improving function while preserving stability. Further studies are needed to strengthen the evidence base.
