Arthroscopic suture pull-through fixation offers stable transosseous fixation while avoiding complications associated with screw fixation.\n\nAim:\nThe aim of this study was to evaluate the functional and radiological outcomes of arthroscopic PCL tibial avulsion fixation using a suture pull-through single-tunnel technique.\n\nMaterials and Methods:\nA prospective, single-center observational study without a control group was conducted in the Department of Orthopedics, N.D. Desai Medical College, from May 2026 to July 2026. Twenty-four patients with displaced isolated PCL tibial avulsion fractures underwent arthroscopic single-tunnel suture pull-through fixation. Lysholm scores and radiological union were assessed at 6 weeks, 3 months, and 6 months; no instrumented posterior laxity testing or additional validated patient-reported outcome measure was available.\n\nResults:\nThe cohort included 24 patients with a mean age of 28 years (range 18\u201360 years). The mean Lysholm score improved from 41.6 \u00b1 3.2 preoperatively to 81.2 \u00b1 5.6 at 6 weeks, 90.7 \u00b1 3.5 at 3 months, and 94.9 \u00b1 2.3 at 6 months (Friedman P &lt; 0.001). All fractures were recorded as united by 3 months on follow-up radiographs, and 22 patients (approximately 92%) reported return to their pre-injury activity level within 4\u20136 months. One patient developed a mild extension lag that improved with physiotherapy. No non-union, fixation failure, or revision surgery was observed during the 6-month follow-up; however, objective posterior translation was not measured.\n\nConclusion:\nIn this small single-center observational cohort, arthroscopic single-tunnel suture pull-through fixation was feasible and was associated with radiographic union and favorable short-term Lysholm score improvement. Because there was no comparator group, objective posterior stability testing, or long-term follow-up, these findings should not be interpreted as evidence of superiority or equivalence to other fixation techniques.\n\nKeywords:\nPosterior cruciate ligament , posterior cruciate ligament tibial avulsion fracture , arthroscopy , suture pull-through technique , single-tunnel fixation , Lysholm score , knee instability<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i10.8302","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T17:21:37Z","timestamp":1791393697000},"page":"408-414","source":"Crossref","is-referenced-by-count":0,"title":["Arthroscopic Posterior Cruciate Ligament Tibial Spine Avulsion Fixation Using a Suture Pull-Through Single-Tunnel Technique"],"prefix":"10.13107","volume":"16","author":[{"given":"Parth Jayeshkumar","family":"Patel","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Dr. N.
