OSI Joint Preservation Products

OSI's largest product category — arthroscopic visualization, portal access, debridement, ablation, and microfracture instrumentation supporting joint preservation procedures of the shoulder, hip, and knee.

Arthroscopic Visualization

The Q Arthroscopy System

Available in Q3mm, Q4mm, and Q5mm configurations (30°/0°). The Q3/Q4 are housed within a single inflow arthroscopic sheath designed for superior maneuverability and visibility; the sheathless Q5 acquires illuminated anatomic structures and non-digital 3D images. Designed for use with the OSI Clear Cannula in shoulder, hip, and knee arthroscopy, including intraosseous endoscopy during core decompression.

Portal Placement

Targeting Guide

A detachable guide for precise needle localization within the joint to establish a second arthroscopic portal.

Second-Portal Visualization

The Clear Cannula

A smooth-surfaced, directionally-seamed cannula that facilitates precise second-portal placement and increases the luminosity of the Q Arthroscope. The first and only cannula of its kind to provide real-time images in the z-axis, minimizing extravasation and soft-tissue swelling.

Ablation & Cautery

ThElator

A low-pulse tissue ablation and cautery device that concentrates electron emission at the tip of the probe. Inline suction keeps the operative field clear, and the device attaches to a standard generator, eliminating the need for special equipment.

Debridement Curette

The Red Belly (3.5S / 4.5S / 4.5L)

A handheld, serrated curette designed for configurable, aggressive debridement of the posterior knee and other hard-to-reach areas, including the anteromedial humeral head in the shoulder joint. Inline suction removes all debris.

Debridement Curette

The Angler (3.5S / 4.5S / 4.5L)

A handheld, smooth curette designed for configurable, smooth-surface debridement of the tibial plateau and curvilinear femoral condyle.

Outflow Management

The Egret

A patented outflow adaptor that engages the Angler or the Red Belly. Its rotational engagement mechanism allows the configured curette to be positioned precisely in any hard-to-access area.

Microfracturing

The Safety PX (5mm / 10mm / 12mm)

Designed to variably penetrate subchondral bone at areas of cartilage loss. The short version supports articular surface microfracturing of the knee; the extended version supports non-articular intraosseous subchondral microfracturing of AVN and bone marrow edema lesions.

H

Posterior Knee Repair

The Harpy

Comprises a precision 4mm cannula with a targeting guide for the Q 3mm arthroscope and a shortened arthroscopic sheath for non-digital 3D imaging — used for posterior knee visualization during meniscus root repair or debridement.

Burrs of Prey® Unshrouded Debridement System

OSI's patented unshrouded burrs are designed for intraarticular saucerization and micro chondroplasty, each shaped for a specific anatomic access challenge.

180mm

Harrier X / Harrier EX

Smooth-surfaced burr that captures frayed pieces of cartilage, characterizing a true micro chondroplasty. Used for hip arthroscopy and micro chondroplasty at the acetabular rim.

132mm

Harrier S / Harrier SX

Ideal for sub-meniscus micro chondroplasty and meniscus root debridement, and for rapid micro chondroplasty in the patellofemoral sulcus.

180mm

Falcon / Falcon X

Ideal for sub-labral pincer debridement — debrides the chondrolabral junction and central acetabular osteophytes for CAM lesion management without detaching the labrum.

180mm

Talon

A smooth, curvilinear head designed to smooth over areas of chondromalacia.

180mm

Eagle / Eagle X

Round-headed burr ideal for backstroke debridement of the medial margin of the sourcil and traditional CAM lesions.

180mm

Vulture

Long, cylindrical shape ideal for rapid removal of prominent osteophytes along the anterior, medial, and lateral osteochondral junctions of the femoral condyles during intraarticular saucerization of the knee.

Low-pressure, syringe-free delivery systems for autologous bone marrow aspirate and cancellous bone graft.

Graft Delivery

The Biomass Delivery Trephine

A unique product designed for low-pressure delivery of any selected amount of bone marrow aspirate and viscous cancellous bone graft. Auto-concentration technology allows for syringe-free, handheld delivery of any graft composite. Used with the OSI Irrigation Needle, which removes oxLDL, fat, and inflammatory cytokines from the host bed prior to grafting.

Graft Delivery

The Biomass Delivery Curette

Shares the Biomass Delivery Trephine's low-pressure, auto-concentration, syringe-free delivery design. Used for subchondral and greater-tuberosity bone marrow edema lesions and aseptic loosening lesions; irrigation removes oxLDL, fat, and inflammatory cytokines from the host bed.

Host-Bed Preparation

OSI Irrigation Needle (17-g Blunt Tip)

Directs an irrigation stream strategically within the host bed to remove oxidized LDL, fat, and inflammatory cytokines — used alongside the Biomass Delivery products for pre-grafting site preparation.

Cancellous Graft Delivery

The Bone Shuttle

A simple but unique product for open or percutaneous delivery of morselized cancellous bone. The right-angle, side-loadable tray makes graft delivery safe, simple, and efficient, with dimensions configured for neutral-pressure graft delivery to avoid embolization.

Implantable stabilization systems that secure bone graft within the femoral or humeral head following core decompression and debridement for avascular necrosis (AVN).

AVN — Femoral Head

The Hip Tool

Stabilizes bone graft within the femoral head after endoscopically guided core decompression and thorough debridement for AVN. Stabilization allows early postoperative passive range of motion and more extensive debridement consistent with removal of the avascular burden. Implant angles 125°–140°; removable hardware.

AVN — Humeral Head

The Trans-Scapular Y (TSY) Shoulder Plate

Stabilizes bone graft within the humeral head after endoscopically guided core decompression and thorough debridement for AVN, enabling direct joint-surface elevation. Implant angles 130°–140°; removable hardware.
