82 products · sorted by price (high to low)


Knee arthroscopy listings include ACL drill guides along with graft and meniscus instruments. Total knee listings include Stryker Triathlon guides and other Triathlon instruments. Femoral and tibial instruments appear as well. You will also see impactors, trials, patella instruments and knee instrument sets. Knee retractors and Smillie pattern instruments are listed too. Titles name makers such as Stryker, Acufex and Arthrex, plus Smith & Nephew and Linvatec. Clear Choice Medical sells these as an independent dealer without manufacturer ties.
Check the title and photos of each guide for any side marking. Knee trials are sized within a single system family, so match both the system name and the size marking. Arthroscopic knee instruments differ in working length and tip angle, which you can compare in the title and photos. Availability changes as items sell, so confirm exact model and size details in the current listing rather than the category name. Browse the knee listings, or reach out to Clear Choice Medical if a marking is unclear.
Common questions about Knee
What is an ACL guide?
An ACL guide is a drill guide that sets the position and angle of a drill. That is how the GMDN device vocabulary classes the tibial guides in ACL systems. The name covers several parts within one system. ConMed's Infinity system lists separate tibial tip, elbow and footprint guides. Smith & Nephew lists Acufex Director ACL aimers in tip and elbow versions. It also lists femoral offset aimers in sizes such as 6.5 mm and 9.5 mm. Match the system name and part number of each piece to the set you already use.
What do CR and PS mean on knee trials?
CR means cruciate retaining and PS means posterior stabilized, two design types in total knee systems. A Cochrane review describes a PS design as one whose insert has a central post that can engage a cam on the femoral part. Trials are made for each type. Triathlon device records, for example, list separate solid tibial insert trials marked CR and PS. So a CR insert trial is a different item from a PS insert trial in the same system. Match the letters, the system name and the size marking to the set you are completing.
What is a patella clamp?
A patella clamp is a knee instrument that grips the patella, and the name covers several designs. Device records list patella cement clamps and patella clamps that also serve as drill guides. Some systems split the clamp into separate parts. Triathlon records list a patella clamp and a patella clamp jaw under their own catalog numbers. Another maker lists drill guide heads for its clamp under size codes such as PCD12 and PCD16. So check whether a listing is a complete clamp or a single jaw or head. Then match the catalog numbers to your system.
