Arthrex Medium Reverse Punch – 15° Up Tip for Arthroscopic Meniscal Resection

Arthrex Medium Reverse Punch, Peak Surgicals SKU PS-000027, is a reusable arthroscopic tissue punch configured with a straight 3.4 mm shaft and medium reverse cutting jaw angled 15° upward for controlled intra-articular soft-tissue resection. Peak Surgicals lists this instrument in used condition at $84.70. The reverse-jaw orientation allows tissue to be engaged and cut while the working tip approaches the target from a retrograde direction, and the 15° upward profile improves access where a straight reverse punch may not align effectively with the intended tissue plane. Arthrex specifically identifies 15° up medium punch geometry as useful for increased access to the posterior meniscus. The 3.4 mm shaft provides the established working diameter used across Arthrex medium arthroscopy punches, while the corresponding medium punch family uses a 2.5 mm bite classification. This configuration is suited to arthroscopic meniscal resection, contouring of unstable meniscal tissue, and related knee arthroscopy procedures requiring controlled mechanical tissue removal through a portal-based approach.

15° Up Reverse Jaw and Arthroscopic Punch Mechanism

The Arthrex Medium Reverse Punch combines a straight 3.4 mm shaft with an upward-directed reverse cutting jaw. During use, the distal jaw is positioned around the selected arthroscopic tissue margin and handle compression activates the mechanical cutting surfaces at the tip. The reverse configuration changes the direction in which tissue is captured relative to a conventional forward-biting punch, allowing the surgeon to address tissue that is more effectively approached in retrograde orientation. The 15° upward tip further modifies the distal working angle without requiring a curved main shaft. This is particularly useful when portal orientation and joint anatomy make a completely straight reverse tip difficult to align with the posterior meniscal surface. Arthrex documents medium reverse punches with a 3.4 mm shaft and 2.5 mm medium bite classification. The surgeon controls each resection mechanically through jaw placement, handle closure, and repeated visualization rather than through powered cutting. Only the tissue intended for removal should be positioned within the jaw before closure, with cartilage and other protected intra-articular structures kept outside the cutting path.

Posterior Meniscus and Arthroscopic Resection Workflow

During knee arthroscopy, the Arthrex Medium Reverse Punch can be introduced through an appropriately selected working portal after diagnostic evaluation has identified unstable or nonviable meniscal tissue requiring mechanical resection. Arthrex specifically notes that a medium punch with a 15° up tip provides increased access to the posterior meniscus, where the relationship between the femoral condyle, tibial plateau, and portal trajectory can restrict a conventional straight cutting approach. The surgeon advances the 3.4 mm shaft under arthroscopic visualization, positions the reverse jaw around the selected tissue margin, and closes the handles to remove a controlled bite. Sequential small resections can then be used to contour the residual meniscus while preserving stable functional tissue. The punch should be withdrawn or repositioned between cuts whenever the required bite direction changes. Mechanical cutting should remain under continuous visualization so articular cartilage, cruciate structures, capsule, and other protected anatomy remain outside the jaw. The instrument is particularly useful where retrograde jaw orientation creates a more favorable cutting relationship than forward-biting arthroscopic punches.

PS-000027 Configuration and Arthrex Family Identification

Peak Surgicals SKU PS-000027 is publicly described as an Arthrex medium reverse punch with a straight shaft, 3.4 mm shaft diameter, and 15° upward tip. Arthrex's current handheld arthroscopy catalog documents two medium reverse instrument families with this exact functional geometry: the Series I AR-12570 and the WishBone AR-12570W. Both use a 3.4 mm shaft and are specified as straight-shaft, medium, 15° up, reverse punches, with the medium bite category measuring 2.5 mm. The Peak product page, however, does not publish the original Arthrex item number, so PS-000027 should not be relabeled definitively as AR-12570 or AR-12570W until the engraved identifier has been physically confirmed. The displayed product image uses a traditional finger-ring style handle rather than the distinctive WishBone configuration, which is consistent with Series I-style geometry but is not sufficient by itself for definitive catalog assignment. Procurement records should therefore retain Peak SKU PS-000027, used-condition status, 3.4 mm shaft, medium reverse jaw, and 15° up-tip specifications while separately recording the original manufacturer number once verified.

Reusable Instrument Reprocessing and Used-Device Procurement

Peak Surgicals lists this Arthrex Medium Reverse Punch as reusable medical-grade steel and specifically identifies the product condition as used. That status should remain clearly visible in the product description because institutional buyers need to distinguish a pre-owned reusable instrument from new inventory. Before clinical service, a used arthroscopic punch should undergo complete inspection, cleaning, functional assessment, and validated sterilization in accordance with the original manufacturer's reprocessing instructions and the purchasing facility's protocols. Particular attention should be given to the reverse cutting jaws, pivot mechanism, shaft, handle movement, and cutting-edge approximation. The jaws should open and close smoothly, meet correctly, and remain free from deformation, corrosion, retained debris, or cutting-edge damage. The 3.4 mm shaft should also be inspected for bending or structural damage that could affect portal passage or distal alignment. Peak displays CE, FDA, and ISO certification badges on the storefront; hospitals should nevertheless qualify the exact Arthrex device identity and original regulatory documentation independently rather than interpreting retailer badges as proof of individual device approval.

How does the Arthrex Medium Reverse Punch differ from a standard forward-biting arthroscopy punch?
The Arthrex Medium Reverse Punch cuts tissue through a reverse-jaw orientation rather than the conventional forward-biting relationship. This allows the surgeon to engage a tissue margin from a retrograde direction when portal geometry makes forward cutting less effective. The 15° upward tip adds additional distal access while retaining a straight main shaft. A standard forward punch may be more convenient when the target tissue lies directly in line with the portal and shaft. Both instruments provide mechanical tissue resection through manual handle closure. Selection should depend on meniscal location, tear morphology, portal position, desired cutting direction, and surrounding intra-articular anatomy.

Why is the 15° up tip useful for posterior meniscal access?
Arthrex specifically describes the medium 15° up-tip configuration as providing increased access to the posterior meniscus. The slight upward angle changes the relationship between the distal cutting jaw and the straight 3.4 mm shaft. This allows the working end to reach tissue that may sit beyond the ideal cutting line of a completely straight reverse punch. The angle can reduce the amount of shaft manipulation needed to orient the jaws toward the selected posterior meniscal margin. Arthrex Medium Reverse Punch geometry should still be selected according to portal placement and individual joint anatomy. The surgeon must maintain arthroscopic visualization throughout positioning and cutting so articular cartilage and other protected structures remain clear.

What do CE, ISO 13485 and FDA references mean when purchasing this used Arthrex instrument?
Peak Surgicals displays CE, FDA, and ISO certification badges on the Arthrex Medium Reverse Punch listing. ISO 13485 relates to medical-device quality-management systems and does not independently establish the regulatory status of this specific used instrument. Original Arthrex catalog and regulatory documentation should be matched to the engraved manufacturer item number when institutional traceability is required. The Peak listing does not currently publish that original Arthrex catalog identifier. The geometry corresponds to the AR-12570 or AR-12570W medium 15° up reverse family, but this should not be substituted for physical model verification. Hospitals should retain seller records, original device identification, condition documentation, and applicable manufacturer regulatory records within their procurement files.

How does the reverse punch mechanism control meniscal tissue resection?
The Arthrex Medium Reverse Punch uses manually actuated opposed cutting surfaces at the distal working end. The surgeon positions the reverse jaw around the selected meniscal tissue while viewing the working end arthroscopically. Closing the finger handles transmits mechanical force along the instrument and closes the cutting jaw to remove a controlled bite. Releasing the handles allows the working end to reopen for repositioning. The medium Arthrex reverse family uses a 3.4 mm shaft and a documented 2.5 mm bite category. Controlled meniscal contouring is achieved through repeated small bites rather than attempting to remove an excessive tissue segment during one closure.

How should hospitals inspect and reprocess this used Arthrex Medium Reverse Punch?
Because Peak Surgicals explicitly lists PS-000027 in used condition, incoming inspection should be completed before the instrument enters a clinical arthroscopy tray. Staff should inspect the 15° reverse jaw for cutting-edge damage, misalignment, deformation, corrosion, or retained debris. The handle and internal pivot action should operate smoothly and the jaws should fully open and approximate correctly. The 3.4 mm straight shaft should remain free from bending or visible structural damage. Cleaning and sterilization should follow the original Arthrex reusable-instrument instructions and the healthcare facility's validated processing protocol. The instrument should return to service only after functional integrity, cleanliness, traceability, and suitability for reuse have been confirmed.
